Updated with the free games available in September

If you have PlayStation Plus, you automatically get free games for your Sony consoles. Two are made available to download on the first Tuesday of every month for each Sony system. If you haven't been taking advantage of the opportunity to build up your PSN games library at no additional cost, now's a great time to start.

It can be tough to keep up with all of the gratis on the new hardware and the free PSN games inbound for last-gen's PS3 and Vita. That's why we've put together this list (which we'll continually update) with the Instant Game Collection titles coming each month, and those titles from previous months you've sadly already missed (so don't expect them to join the free rotation again anytime soon). Take a look at this month's free PlayStation games, starting with...

Grow Home (PS4): You're a few thousand vertical meters away from your spaceship, and the only way back up is to grow, grow, grow. Climb the Star Vine one hand at a time, and grow it up one offshoot as a time, as you delight in the procedurally animated ambling of the Botanical Utility Droid (B.U.D.) The further you go, the more power-ups you find, the faster B.U.D. can climb the Vine - but you're always one misstep away from one heck of a fall.

Super Time Force Ultra (PS4): It looks and plays like a retro action game, but Super Time Force Ultra is just as much of a puzzler. Instead of always just charging straight forward, you can pause and rewind time - at which point you'll find you're fighting alongside your old self. It will take ample experimentation to figure out the right combination of characters for each challenge… and plenty of good old running and gunning.

Twisted Metal (PS3): The series that made car combat a staple of video gaming returns. Play through the classic multiplayer mode with up to 16 players at a time, or make your way through Calypso's Tournament alone or with a friend. With seventeen vehicles to outfit and take into the arena, Twisted Metal should keep you busy until the next car combat revival rolls around.

Teslagrad (PS3, PS4): Teslagrad is what would happen if If Nikola Tesla moved on from the AC induction motor to magnetic gloves and teleportation boots instead of Wardenclyffe Tower. Playing as a young boy on the run from a despot, you must climb the Tesla Tower and collect its powerful treasures to make your way past challenging puzzles and boss battles.

La-Mulana Ex (PS Vita): La-Mulana was a tough, Metroid-inspired backtracking sidescroller before tough, Metroid-inspired backtracking sidescrollers were cool. La-Mulana brings all the challenge to a portable home on PlayStation Vita with some new mechanics to make it slightly more welcoming. It's still prone to induce fits of cursing between the "ah-ha!" moments, though, so maybe keep that in mind before you take it on the bus.

Xeodrifter (PS Vita, PS4): The creators of Mutant Mudds move their retro aspirations a few years forward with this Super Metroid/Blaster Master inspired side scroller. The pixels are chunky, the enemies are many, and the bosses are tough. It won't take you too long to clear out Xeodrifter's world, but if there's any love for Metroid in your heart, you'll love every minute.

Lara Croft and the Temple of Osiris (PS4): Old-school Lara returns to top-down action puzzling in this follow-up to Guardian of Light. This time she can partner with up to three other players, taking on the roles of a fellow treasure hunter and two ancient Egyptian deities made flesh. Together they clear dungeon rooms and solve puzzles, naturally.

Limbo (PS4): It's dark, you're alone, and there's a really frickin' huge spider after you. Limbo starts off grim and stays that way, but its moody world full of tricky platforming and physics puzzles will make you want to see it through to the end.

God of War: Ascension (PS3): We all know Kratos' quest for vengeance began when Ares tricked him into killing his wife and daughter, but that was ten years before the original God of War. Ascension follows Kratos immediately after his revolt from Ares, tracking down the Furies that imprisoned him before he can start his quest in earnest. It also has a pretty unique competitive multiplayer mode.

CastleStorm (PS3, PS Vita): Build a castle for your Viking or knight army, then send out legions of troops as you try to knock down your rival's. You'll have to divide your attention between managing troops and sending projectiles sailing into enemy fortifications if you want to be crowned the victor of this two-dimensional skirmish.

Sound Shapes (PS Vita, PS4, PS3): Sound Shapes' levels all move to the beat, so if you want to make your way to the end of Beck's "Cities," you'll have to feel the rhythm. Not to mention you can make your own throbbing platformer levels with the level editor, which works particular well with the Vita touchscreen.

Stealth Inc. 2: A Game of Clones (PS Vita, PS4, PS3): Use a bounty of new equipment to keep your little goggles-wearing clone alive as he explores the great big facility where he was manufactured. And this probably goes without saying, but don't get caught - it won't end well.

Rocket League (PS4): Picture soccer/football, but instead of a bunch of guys in shorts chasing a ball, they're all customizable futuristic automobiles. And instead of rules about going "offsides" and "not ramming full speed into your opponent and blowing them up" the pitch is sprinkled with regenerating turbo fuel. And the cars can drive on walls and do backflips. Add up to four-player local and eight-player online multiplayer and you're starting to get the idea of Rocket League.

Styx: Master of Shadows (PS4): Play as a grizzled goblin assassin as you scale the Tower of Akenash, giving elves, humans, and other freakish monsters the slip and/or a dagger in the back. Upgrade your arcane abilities to detect foes beyond sight and even create arcane clones to scout ahead or create diversions. This is the prequel to Of Orcs and Men, telling Styx's story before he meets up with Arkail, if you happened to play that one.

Rain (PS3): If you think being a little boy alone in the big city during a rain storm sounds bad, just wait until you try it while you're inexplicable invisible. You can only see your character by his outline in a downpour, adding a unique wrinkle to the soggy adventure - but at least all you have to do to hide from the monsters is stand under a canopy.

MouseCraft (PS3, PS4, PS Vita): Filled with enough cheese puns to cause minor indigestion in the lactose intolerant, MouseCraft is a Lemmings-style side-view puzzler. But instead of turning your three little mouse charges into blockers or bridge builders, you must drop a set array of tetrominoes to bridge gaps and other hazards on their way to a plate of delicious cheese. Also there's a mad scientist cat with a bad German accent.

Geometry Wars 3 (PS Vita): Geometry Wars has some of the most compelling, intoxicating gameplay ever created by human hands. So it's particularly impressive that the third title in the franchise manages to evolve the formula without squashing what made it great, adding three-dimensional, curving levels across an escalating adventure mode. If you haven't already played Geometry Wars 3 on PS3 or PS4, get started on Vita.

Entwined (PS Vita, PS3, PS4): Ah, to be a young bird and fish in love. It will take a pair of steady thumbs to guide Entwined's pair of unlikely soulmates through nine distinct lives full of rhythmic challenges, but once you make it, you'll find them united in the form of a beautiful, powerful dragon. Which sounds way cooler than exchanging rings, to be perfectly honest.

Metal Gear Solid V: Ground Zeroes (PS4): Big Boss (aka Snake) is back is his sneaking suit again. To tide you over until the release of (literally), but there are plenty of sneaky scavenger hunts, extra modes, and challenges to overcome in Snake's first open-world environment.

Skulls of the Shogun: Bone-A-Fide Edition (PS4): When ancient warriors die, what do they do in the afterlife? Continue their battles as their skull-faced, post-life selves, apparently. Skulls of the Shogun is a turn-based strategy game that lets you build up your own army of undead samurai warriors, complete with an engaging story of your fallen general uncovering the mystery behind his own murder.

Call of Juarez: Gunslinger (PS3): Call of Juarez: Gunslinger has everything you could ever want out of an FPS set in the Wild West. There are shootouts, duels, stories of revenge, and run-ins with legendary outlaws like Billy the Kid, Butch Cassidy, and Jesse James. The arcade-style gunplay puts an emphasis on trick shots and chained combos, making each engagement a challenging battle for your life (and a top score).

Cloudberry Kingdom (PS3): When you hear the name Cloudberry Kingdom, it probably doesn't convey the nightmarish gauntlet of death traps you'll need to navigate in order to progress in this platformer. The procedurally generated levels are jam packed with thousands of spikes, flamethrowers, lasers, and just about any other deadly object waiting to obliterate you. All you can do is hop, skip, and jump from one seemingly safe platform to the next. Good luck.

Super Exploding Zoo (PS Vita, PS4): Don't let the bizarre title deter you; Super Exploding Zoo is not a game about placing explosives in animal cages. Instead, alien monsters are invading a zoo with the intent of capturing all of the eggs and babies housed within. As a herd of angry, exploding animal defenders, you must protect the youngins by charging through the exhibits and destroying every last extraterrestrial.

Futuridium EP Deluxe (PS VIta, PS4): Futuridium is a endless runner, retro shooter, and puzzle game all crammed into one game. This high-speed, psychedelic experience that will put your twitch reflexes to the test. Destroy enemies and blast cubes to build up a massive score multiplier and rise to the top of the leaderboards all to the tune of some hypnotic techno.

Guacamelee! Super Turbo Championship Edition (PS4): If you ever wanted to wear a Mexican Luchador mask and lay the smack down on some bad guys using super powered wrestling moves, here's your chance. Part side-scrolling beat 'em up, and all Metroid-style adventure, Guacamelee takes you through a wondrous and beautiful world based on Mexican folklore. The game is filled with challenging enemies, quirky characters, and complex environmental puzzles that will push your platforming skills to the limit. You don't want to miss this one.

Ether One (PS4): Ether One is a fresh addition to the PlayStation Network. In it, you explore the minds of the mentally ill as you attempt to piece together the significant events of your patients' lives. You'll need to solve complex puzzles as you explore creepy environments all while trying to make sense of some pretty trippy situations.

The Unfinished Swan (PS4, PS3, PS Vita): May's other first person, exploration puzzle game comes in the form of The Unfinished Swan, in which you must overcome a variety of environmental puzzles using paint as you uncover the details of a whimsical fairytale. Discovering the world hidden in the white nothingness is an fascinating experience, making the unique artstyle and evolving world one you won't soon forget.

Race the Sun (PS4, PS3, PS Vita): In Race the Sun, nighttime is not your friend. In fact, you want to avoid the blackness of night so badly that you hop into a rocket-powered ship and chase the sun. As you can imagine, the sun never takes a break from trying to set on you, so this race goes on forever. Avoid every obstacle, collect power-ups, and enjoy the serene soundtrack as you chase that giant, burning ball of gas.

Hohokum (PS4, PS3, PS Vita): There are a lot of games out there that strive to stress you out, but Hohokum is not one of them. In it, you control a flying, snake-like...something. We're not quite sure what it is, but it's friendly and likes to explore. As you cruise around the colorful world, you'll see the environment change around you and strange creatures will hop on you're back for a free ride, letting you all just enjoy the scenery together. It's a nice change of pace.

Murasaki Baby (PS Vita): And to top things off with something a little weird, here comes Murasaki Baby - 2D puzzle platformer set in a nightmarish world with a creepy, Nightmare Before Christmas vibe. In it, you'll need to guide Baby - an innocent and frightening-looking baby with an upside-down head - through some bizarre landscapes as you try to get her back home. Although the baby may just freak you out, it's endearing to hold her hand and guide her past obstacles and enemies with the Vita touchpad.

Tower of Guns (PS4, PS3): Tower of Guns puts you in a tower and lets you shoot up bad guys with lots of guns. Who'd have thought? As you ascend the tower, you encounter a random array of enemies and blow them to smithereens with your projectile launcher of choice before facing the boss at the top. The game is designed for quick gameplay sessions, giving you a chance to scratch that twitch shooter itch, explode things, then move on with your day. What could be better?

Never Alone (PS4): Never Alone is a 2D platformer that's based on the lore of the Alaskan Native people called the Iñupiat. In it, you play as a young girl and her pet fox as they attempt to find the source of an eternal blizzard that threatens her people. The game challenges you to overcome the harsh, Arctic environments filled with vicious polar bears, unstable glaciers, and aggressive natives with only a bola weapon and the help of friendly spirits.

Dishonored (PS3): As the master assassin Corvo Attano, you must uncover and assassinate (or otherwise get rid of) the group behind the murder of Dunwall's empress. Dishonored's open levels give you complete freedom to approach your missions the way you want. Should you sneak your way past the guards using your blink ability to move through the shadows, or jump into a battle head on and brutally eviscerate your enemies with your rat summoning abilities? The choice is yours.

Aaru's Awakening (PS3, PS4): Looking for a platforming challenge that's on par with Super Meatboy's difficulty? Well, give Aaru's Awakening a shot. This beautiful 2D platformer puts you in control of Aaru - a part bear, part bird creature with the ability to air dash and teleport at will. The levels challenge you with complex puzzles that call for precision jumps and nerves of steel as you avoid the environment's deadly traps and monsters.

Killzone Mercenary (PS Vita): Killzone Mercenary has just about everything you'd expect in a console game, only this PS Vita FPS lets you take it on-the-go. The single-player campaign takes you through the events that happened between Killzone 2 and Killzone 3 as mercenary soldiers that fight on both sides of the war. Plus, if you're looking for multiplayer, Mercenary allows for 8-player multiplayer matches with 8 maps and 25 guns. Not too shabby.

Monsterbag (PS Vita): Monsterbag's innocent looking art style sure does well to hide the dark undertones if its world. A bag-shaped monster named V accidentally gets separated from its friend, Nia, and it's trying to get back to her. Unfortunately, the world V lives in isn't too fond of monsters, and any human who catches V in their sights will beat it to death out of fear. As V, you'll need to sneak through the game's puzzles, using your monster powers to distract potential aggressors and get to Nia safely. Oh, and if you don't reach your friend in time, you might trigger the apocalypse.

Oddworld: Abe's Oddysee - New n' Tasty (PS4): The old alien world platformer has been completely remastered with enhanced visuals, redone voice acting, and brand new cutscenes to bring Abe into the new generation. The side-scrolling platformer once again puts you in the depths of an alien meat processing facility as Abe - the company's once employee of the year.

Valiant Hearts: The Great War (PS4): There aren't many games set during the events of the first World War, but Valiant Hearts breaks new ground with the setting as well as it's emotional storytelling. You play as a variety of participants in the Great War, from a combat engineer to a chef you experience each of the character's personal wartime stories and their relationship with a dog medic named Walt that ties them all together. Adventure style puzzle solving and heartfelt storytelling await.

Papo Yo (PS3): When most game characters encounter terrifying, sharp-toothed monsters, the result is typically a shotgun to the face. Not in Papo Yo. The protagonist, Quico, and his monster must face magically charged puzzles and platforming challenges. Though the in-game environments might be whimsical and bright, there are some dark undertones to the story, resulting in some surprising and touching story telling.

Sherlock Holmes: Crimes and Punishments (PS3): Become the legendary gumshoe as you investigate some of the most criminal violent cases of Holmes' time. you'll need to question witnesses, search crime scenes, and use your power of intuition to see things that no ordinary detective would pick up on. There isn't much hand-holding in Crimes and Punishments. You get the clues, the crime scene, and a lineup of suspects, and you are the one who chooses to pass judgement on the suspected criminal. Be sure to do a thorough investigation. You can just as easily imprison an innocent person as the guilty party.

OlliOlli 2: Welcome to Olliwood (PS4 and PS Vita): If you mashed together an endless runner like Canabalt and Tony Hawk's Pro Skater, you would end up with OlliOilli. The sidescroller challenges you to grind on rails and land long manual tricks between your next stunt to build a high score chain. What appears to be simple quickly becomes an exercise in attaining perfection in each level - which totally becomes the most addicting game, like ever.

Counterspy (PS4, PS3, and PS Vita): Inspired by the Cold War's tactical espionage action, CounterSpy puts you in the role of a secret agent working for a neutral organization against two world powers. You're objective is to prevent a nuclear incident from occurring by taking on missions to sabotage and collect intelligence from both sides. The game functions mostly as a Metroidvania-style side scroller, with some third person cover shooting forcing you to take the stealthy approach to completing your missions.

Transistor (PS4): The creators of Bastion have yet another isometric RPG to tickle your adventure bone. Red, a famous singer, gets her voice stolen and, conveniently enough, comes across a talking greatsword (who ends up doing the talking for her). With a mix of awesome magical abilities, action-oriented gameplay, and fascinating futuristic world, Transistor is a game you don't want to miss.

Apotheon (PS4): The Greek mythology-inspired sidescroller is making it's debut on the PS4 for free. You play as a Greek warrior on his quest to climb Mt. Olympus and fight enemies in a Metroidvania-esque world. The game looks to have a Zelda 2 feel to it as you use your sword and shield to block and slash at enemy soldiers and ancient mythological creatures. And then there's the unique, wall-painting art-style that makes for some fascinating environments.

Yakuza 4: If you're a lover of Japanese mobsters, beating people down with martial arts, or getting lost in a plethora of side missions, you can't go wrong with Yakuza 4. In it, you explore Tokyo's underworld. Outside of roundhouse kicking fools in the streets, there are a bunch of activities to take part in like making a "number 1" cabernet girl, developing friendships with NPCs, and training fighters in your own, personal dojo.

Thief: Garrett the master thief makes his first appearance on the new gen systems, returning to the first-person stealth elements the Thief series is famous for. Don't think that you'll be sneaking around snapping a bunch of guard's necks. Garrett is a thief, not an assassin. You're goal is to hang out in the shadows, grab the goods, and escape before anyone knows you were there.

Rogue Legacy: How can a game that's so brutally difficult be such a pleasure to play? Well, that's a rogue-like for you. That's the way it's meant to be played. Every time you die, you aren't brought back to a checkpoint. You lose your progress and get dropped all the way back to the beginning of the game. Rogue Legacy is one side-scrolling challenge that will dig its hooks into you almost immediately.

Kick Finnick: It a puzzle platformer involving a little boy, his pet robot, and a massive rifle. Yes, the kid can use his big gun to blast enemies to smithereens, but it also plays a huge part in his jumping abilities. The recoil from shooting the gun can blast Kick into the air, he gets grappling attachments, and plenty of other gadgets. With a delightful, cartoon aesthetic, incredibly challenging jump puzzles, and everything from bounce pads to teleporters to mess with, Kick Finnick has all the ingredients for an entertaining, 2D adventure.

Infamous: First Light (PS4): Fetch gets her own standalone spin-off in a campaign that bridges reluctant Seattle superheroics and her imprisonment in the Curdon Cay Conduit detention center. You don't need to own (or even have played) Infamous: Second Son to appreciate First Light, but it will give you some new perspective on the city's totalitarian overseers either way.

The Swapper (PS4/PS3/PS Vita): This mind-bending puzzle platformer explores the mechanical and philosophical implications of creating and destroying a near-endless supply of clones to navigate a seemingly abandoned space station. Make sure you take a break from the mentally taxing challenges to appreciate its awesome atmosphere and kitbashing aesthetic.

Prototype 2 (PS3): Infamous isn't the only superpowered open-world series in January's PS Plus lineup. Prototype 2 takes players back to New York for Sgt. James Heller's mutating quest to consume the original game's protagonist Alex Mercer, and he'll use a bevy of stomach-turning new powers to save/destroy Manhattan on the way there. Did I mention that includes a gaggle of gooey, gorey tendrils?

DuckTales Remastered (PS3): WayForward brings the classic pogo-jumping platformer back to life in this updated take on Scrooge McDuck's globe-trotting adventures. Modern amenities like smooth hand-drawn animation and 3D backdrops are nice, but it's the classic challenge that will keep you coming back for another dip in the money pool.

Duke Nukem 3D: Megaton Edition (PS Vita/PS3): Return to the days when Duke Nukem was a joker instead of just a punchline with this enhanced version of Duke Nukem 3D and three of its expansion packs. Or take a deeper dive into history with the original version with the classic shooter. Just try not to think about Duke Nukem Forever when you do.

Whoa Dave! (PS Vita/PS4 version coming): The developers of the Bit.Trip series return with a retro-arcade inspired… Ok, retro-arcade inspired doesn't cut it when it comes to Whoa Dave!, which is straight up an old-school arcade game minus thirty years of dust and faded cabinet art. Grab pennies, toss bombs at aliens, and go for the high score!

Injustice Gods Among Us (PS4): Ever wonder if Wonder Woman would take down the Flash in a fight? Who would be the victor of an actual battle between Batman and Superman? Well, you can answer these age-old questions by pitting your favorite superheroes and villains against one another in Injustice: Gods Among Us. It has all of the classic Mortal Kombat-style combat (minus the Fatalities) and a pretty cool story mode to boot.

Secret Panchos (PS4): Okay, Secret Panchos is a spaghetti western-themed fighting game, that you play from an isometric perspective. But instead of punching each other into submission, you have to use your quick-twitch reflexes, and character abilities in a gunfight against up to four players. Each character has distinct personalities and skills - there's the Matador that takes the battle up close, the dual pistol-wielding Kid Red, and the skull-faced Phantom Pancho.

Hitman HD Trilogy (PS3): If you haven't yet gotten into the Hitman series, here's your chance. Take on the role of Agent 47 as you find the most clever and gruesome ways to assassinate your targets. Should you lie in wait and silently eliminate your enemy, or dress in a chicken suit, equip a silenced pistol, and skip on the finesse. The HD collection includes Hitman 2, Hitman: Contracts, and Hitman: Blood Money, so you've got plenty of game to perfect your killing tactics.

Deadly Premonition: Director's Cut (PS3): You play Francis York Morgan, a federal investigator who comes to a small town to investigate the murder of a young woman. But the investigation is anything but routine. The dead rise up as husks of their former selves, Morgan periodically visits mysterious, supernatural rooms in his subconscious, he talks to a character in his head named Zach, and he gets clues by looking into a cup of coffee. Yup, this is a weird one, but if you can get past the wonky controls and funky visuals, you're in for a treat.

Final Horizon (PS Vita): If you've been looking for a tower defense game, look no further. Final Horizon is mixes RTS gameplay with tower defense as you attempt to fend off waves of insect-like space aliens from eating you colonists. Toted as a "2 minute tower defense" Final Horizon is perfect for those quick mobile gaming sessions on the Vita.

Titan Attacks! (PS4, PS3, PS Vita): Aliens are attacking earth and you're the only one crazy enough to stop them. Also, you're probably the only one with a massive tank at your disposal. Titan Attacks! is a classic, arcade-style shooter that challenges you to survive wave after wave of alien spaceships. Like the arcade games of yore, this shooter is all about the high scores, so, survive, upgrade your tank, and keep on blasting those space invaders.

The Binding of Isaac: Rebirth (also on Vita): After making Super Meat Boy, a tribute to the great platformers of old, developer Edmund McMillen's next game added a new, creepy twist on the top down gameplay of The Legend of Zelda. The Binding of Isaac already won acclaim on the PC for its gruesome (yet cute) spin on the biblical tale of Isaac. Rebirth is the just-released redefinition of the title in 16-bit style, primed for console owners to fall in love with the sobbing adventurer.

Steamworld Dig (also on Vita): Ever dream of a title that slams together the item collection of Minecraft, the 2D exploration of Metroid, the puzzle-platforming of Mr. Driller, and the persistence of an RPG? That's Steamworld Dig, the robotic Old West title which first came to PS4 and Vita in March. Now that the cross-buy game will be free, you can finally check out this game for yourself and see if you dig it! (Sorry.)

Luftrausers (also on Vita): If you're in the need for a 2D shoot 'em up, but have less than five minutes to spare, Luftrausers will fit snugly into your tight schedule. Made by Vlambeer, the group responsible for the highly addictive Ridiculous Fishing, Luftrausers' German accented take on flight immediately flings your craft into the air, tasking players with the risk/reward of constantly shooting to build up score multipliers or stopping your attacks to give your craft a chance to heal. It has a real "just one more turn" property to it that will pull in many that missed this game prior.

Frozen Synapse Prime (also on Vita): First designed for smartphones, this fast paced strategy game has earned a lot of buzz on PlayStation systems. It's a turn-based tactics game, only it goes much faster because your squads and the enemy's take actions at the same time. You need careful logic and observation to win at this one, which is why each hard fought victory feels earned.

Hungry Horde: Among the many noteworthy indie titles on the handheld, this one hopes to bring a new twist to the zombie trope. The first game from the UK dev team Nosebleed Interactive, Hungry Horde has you leading an ever-expanding undead army in a quest for living flesh, and humanity's forces are hot on your zombie heels. It's a race against the clock to take over as much of the apocalyptic town as you can in each stage of the action-puzzler, a bit like Katamari, only with rotting corpses.

Escape Plan (also on PS4): This title comes from some of the same people as Fat Princess, and was an early hit on the Vita, later making its way to the PS4. The black and white puzzler has you controlling two different characters at the same time as you navigate punishing death traps. Despite the dark subject matter, Escape Plan has a grimly funny tone to keep things light. Our garnered a three out of five, which is good enough to justify getting it for free, if you ask me.

Dust: An Elysian Tail: Dust is an indie game that catches your eye with its beautiful art style, then sucks you in with its engrossing combat. The side-scroller puts you in the role of the anthropomorphic hero, Dust, who holds a sentient, talking sword called the Blade of Ahrah. As you progress through the story, you'll earn new abilities, discovering snow-capped mountains and peaceful glades to explore and leveling up into an even more efficient killing machine. It's like Metroid, except with a fox-like ninja protagonist.

Spelunky: Take the difficulty of the most challenging 2D platformers, cover every single level in all manner of deadly traps and monsters, and make the stages randomize every time you die. Sound crazy? That's Spelunky. Whether you're playing four-player co-op or alone, Spelunky will test your platforming skills. But the good news is: it's a blast to play.

DriveClub PlayStation Plus Edition: As a bonus for October, Sony is offering DriveClub's PlayStation Plus Edition. Think of it as an extended demo of the full title. There are 11 tracks to test your driving skills on and 10 cars to race. Plus, you get access to all of the game modes. Not too shabby.

Batman: Arkham Asylum: Start at the very beginning with the first entry in the can't-get-more-Batman-than-this series with Batman: Arkham Asylum. Looks like the Asylum's security staff wasn't able to contain the ingenious criminals ol' Bats has been cramming in there over the years. Only the Caped Crusader has the gumption to go in there and set them all straight. With some of the best combat, stealth, and puzzle-solving gaming has ever seen, Arkham Asylum is a must-play.

Dungeons Dragons: Chronicles of Mystara: Side-scrolling beat-em ups are some of the best old-school entertainment you can get. With the DD: Chronicles of Mystara collection (which includes Tower of Doom and Shadow of Mystara) you get all of the minion-beating action you could want.

Rainbow Moon (PS3 and PS Vita): If you're looking for a good, old-fashioned tactical RPG, you can't go wrong with Rainbow Moon. All of the classic genre tropes are here: a massive world filled with NPCs to chat with, loot to collect and equip, and enemies to battle in a turn-based, strategy combat system. With a 40-hour story campaign plus end game content, Rainbow Moon is definitely worth the price of free.

Pix the Cat (PS4 and PS Vita): Pix is a kind cat. Most felines would jump at the chance to eat a bunch of helpless duckies, but not Pix. A mix between Pacman and Snake, the game challenges you to build high scores by saving ducklings within a time limit. It's a simple concept, but it'll suck you in before you know it.

PlayStation All Stars Battle Royale (PS3, PS Vita): There's just something that's so enticing about getting a bunch of famous characters together and having them beat the crap out of each other. In PlayStation All Stars: Battle Royale you can pit characters like Kratos, Nathan Drake, Sly, and Fat Princess against one another in a Smash Bros.-style free-for-all. The controls are easy enough for beginners to comprehend, but it also has plenty of depth for those who want to get a real competition going.

Hoard (PS3): In a lot of medieval game settings, you play as the hero who slays dragons, finds massive piles of treasure, and... saves a princess or something. Not so in Hoard. In this adventure, you are the dragon that's running amok across the countryside. You are the one scaring the local townspeople, burning down castles, and collecting mountains of treasure to add to your ever-expanding hoard. It's nice to, you know, roast heroes for a change.

Velocity 2X (PS4, PS Vita): Velocity 2X is a melting pot of game genres. It's like the developers said, "Let's combine the bullet hell gameplay of a top-down space shooter, toss in some puzzle solving, and hey, why not just drop in a Super Metroid side-scroller while we're at it." The sequel has all of the top-down puzzle shooting from the original title, but now you'll be able to hop out of your ship and take the fight to your enemies on foot.

Sportsfriends (PS4, PS3): If you've got a few friends over at your place and you're looking for something to do, here's an easy solution: turn on Sportsfriends. It consists of several, easy-to-play competitive minigames that are an absolute blast in a group setting. There's a pole-vault dueling game, a sports game the combines fighting, a ball, and goal zones for super intense 1v1 matches, and physical game of tag called Johann Sebastian Joust. Need more party games? Sportsfriends has you covered.

Joe Danger (PS Vita): If the old dirt bike racers from the Excite Bike series were to ever quit racing, they'd probably end up like Joe Danger. The job description is basically the same: Ride your bike down a mile-long track, hit the ramps as fast as you can, and pull off quadruple backflips before you land. Joe Danger's gameplay is reminiscient of the racing classic, but this stunt racer mixes things up with fancy ramps, dangerous traps, and tons of collectibles. If you're looking to revisit old-school racing gameplay, Joe Danger is where it's at.

TxK (PS Vita): Remember Tempest? That old, classic game in which you guide a funny U-shaped ship down some tubes and shoot a bunch of equally funnily-shaped objects? The developers behind Tempest released a new version called TxK. The game is basically Tempest in how it controls and places an emphasis on chasing high-scores, but it just looks a whole lot cooler, as the developers took the arcade classic and infused flashy neon explosions (think Geometry Wars). There's nothing like playing a classic, and with TxK the old-school gameplay is just as entertaining as it was back in the day.

Road Not Taken: In Road Not Taken, you play as a ranger who must venture into a vast, enchanted forest to rescue children who apparently thought it was a good idea to wander out into a snowstorm and get lost. The thing is: stay out in the elements to long and you freeze to death. The game challenges you to move from one screen of tile-based, procedurally generated puzzles to the next by defeating enemies and removing obstacles. Every situation you encounter is a balancing act between the energy and resources you expend and the objectives you want to achieve. If you make too many mistakes or are too indecisive the ranger will pass out in the snow and leave the little kids to their (deserved) fates.

Fez: Fez mixes 3D and 2D elements together to make mind-boggling environments for you to explore. The gameplay employs a mechanic that allows you to rotate the perspective of the camera on 3D objects, which in turn manipulates their 2D layout, creating new paths for overcoming blocked routes. The world is full of tons of secrets to find and challenges to overcome--if you haven't played Fez yet, you're really missing out.

Crysis 3: Crysis 3 takes the jungle environment of the first game, the city from the second, and smashes those two locales together to create a literal urban jungle--overgrown buildings and all. As the protagonist Prophet, it is once again up to you to save the world from the invading alien Seph using the environment to your advantage. This time, instead of trying to escape your enemies, you'll be hunting down your prey with the advanced alien technology and an arsenal of weapons at your disposal.

Proteus: This wide-open world filled with color and music is far from the typical adventure title you'll play on your PS3. Proteus is more of an experience than a game. You're dropped onto an island covered in grass, trees, and different types of wildlife. Nothing seems particularly interesting at first, until you start to interact with the world. Playing with butterflies will make them sing, chasing rabbits will kick up a beat, and the sky will put on a light show as you activate parts of the world and unlock the soundtrack of the wilderness. Woah...It just got really New Age in here. Just go check out Proteus and you'll know what I mean.

Metrico: Platformers are platformers. We've all played them before. Jump on the blocks and don't fall into the pits. That's easy enough, right? But what if a game turned those rules on their head and mixed them around a bit? Now forward makes you jump, jumping makes that platform over there move left, and moving left makes that same platform move right. Sound confusing? That's Metrico: a collection of seemingly simple platforming puzzles that each have different rules. All you have to do is move from one side of the screen to the other. Can you figure it out?

Dragon's Crown: If you like the old-school beat-em ups, Dragon's Crown is for you. It's got all of the hacking and slashing you could ever want plus a few RPG influences in the mix. You can choose your character from collection of distinct classes, each with unique abilities and looks. In fact, the visual style is most likely one of the first things that will catch your eye. The incredibly disproportionate anatomy of the heroes and heroines is a tad excessive, but hey, I can't say that the characters don't look really cool.

Towerfall Ascension: Towerfall Ascension is the ultimate test of timing and skill, and probably the most fun you're going to have playing multiplayer on the PS4. Each player controls an archer in a confined, vertical arena, and is tasked with massacring the competition with precise arrow shots or stomping them on the head Mario-style.

Strider: The classic ninja series returns with all of the sword-slashing, side-scrolling action you remember from the original games. Explore the metroidvania-style world as you slash through enemy robots, battle massive bosses, and collect new gadgets and abilities to become an unstoppable assassin.

Dead Space 3: Isaac Clarke once again returns to the horrors of deep space to chop mutated monstrosities to pieces. This time Isaac is looking to uncover the source of the Necromorph outbreak, but he won't be facing the hideous killing machines alone. Joining the adventure is John Carver, a soldier and optional drop-in drop-out partner that a second player can control with the campaign's co-op feature.

Vessel: This side-scrolling adventure is all about controlling the flow of water, lava, and other types of experimental liquid. As the inventor Arkwright, you must stop fluid machines called fluros (of course) from wreaking havoc across the world. To do that you'll have to make use of the game's liquid simulation to solve various physics and liquid-based puzzles. But you won't just be playing with harmless water as you slosh it around in your pressurized backpack--you'll use molten lava and other properties to make the various liquids melt, change forms, explode, and more.

Muramasa Rebirth: Muramasa is a fantastic adventure that makes a great addition to your game collection--just to look at the beautiful art design for the characters and environments! But there's more to it than the hand-painted visuals. You can play as two distinct characters, each with a unique storyline, and there are a ton of intimidating bosses to overcome. You hack and slash your way across feudal Japan, collecting dozens of magical swords with special abilities along the way.

Doki-Doki Universe: The world of Doki-Doki Universe might just be as odd as its title. The game takes on a hand-drawn aesthetic, with a lanky-armed robot as the protagonist and any number of wacky characters to assist in quests. The robot QT3 has the power to materialize objects out of thin air, which you can use to help characters living on the game's many planets. If you're looking for a slow-paced adventure through a quirky and sometimes bizarre world, you can't go wrong with Doki-Doki Universe.

Pixeljunk Shooter Ultimate: Venture into the depths of various hazardous environments as you attempt to rescue scientists and solve puzzles. This is accomplished through your power to manipulate water and lava, as well as blast through rocks and ice. Pixeljunk games always provide a good time, and Shooter Ultimate is no different.

Trine 2: Complete Story: Stop me if you've heard this one: A knight, a wizard, and a thief go on an epic 2D side-scrolling adventure. No? Well then you clearly don't know Trine, which drops you into a beautifully stylized fantasy world full of mind bending physics-based puzzles and dangerous enemies.

NBA 2K14: Digital Lebron has never looked more like the real life LeBron than in . Aside from the expected competitive ballin' gameplay, 2K14 also adds the new LeBron: Path to Greatness mode. This campaign lets you progress through the pro player's career, and gives you access to new signature skills that boost attributes and abilities.

Sly Cooper: Thieves in Time: Want to know where Sly gets his natural sneaking skills and unique thieving abilities? Traveling back in time and meeting the stealthy raccoon's ancestors will clue you in. In , you'll help Sly and his buddies recover the pages of the Thievius Raccoonus by visiting the past and teaming up with Sly's ancien relatives.

Terraria: 2D building games come a dime a dozen these days (and other ), but few of them do the genre justice better than Terraria. You'll explore colorful environments, harvest materials by digging into the ground and chopping down trees, then build whatever the hell you want, whether that be a little hut or a massive stone...erm...obelisk?

Mutant Mudds Deluxe: Mutant Mudds have landed on Earth and their invasion is underway. The fate of humanity now lies with a geeky kid Max, who's armed with a water gun and a jetpack. The jetpack isn't just for hovering over sword-wielding Mudds--the 2D shooter also allows to you jump between the background and foreground of the environment using special launch pads.

Stick It to the Man (available now): Remember those pink sticky hands you get from gumball machines that get really dirty when they touch anything? Well, this platformer attaches one of those to your head and gives it weird mind control powers. Along with the bizarre art style and gameplay, experiencing these wacky characters is enough to warrant the hard drive space in your PS4 to give this one a shot.

Puppeteer (available now): In , you take the role of Kutaro, a lost boy that transformed into a doll, lost his head, and has been imprisoned by the Moon Bear King. The entire side-scrolling adventure is set on the backdrop of a puppeteer's stage, with an ever-transforming environment building up and breaking down as you progress through the beautifully designed levels.

Skullgirls Encore (available now): Skullgirls Encore is a 2D fighter that has similar mechanics to the Marvel vs. Capcom games, but with buxom girls beating each other to a pulp instead of superheroes. The gameplay will have you delivering extensive hyper combos, performing characters assists, and battling other players with teams of up to three female fighters.

Pro Evolution Soccer 2014 (available now): If you're going to play any sports game, it's probably best to start off with the most recent iteration. PES 2014 offers improved ball control, enhanced physics, and improved player collision over its predecessors, making it the most realistic PES entry to date.

Soul Sacrifice (May 6, to May 13): The third-person action RPG gives you control over a hero that can assimilate the souls of your defeated enemies. You to decide whether to become more powerful in one attribute of your character at the detriment of another. But other than how you level, your decisions can also affect which of your party members lives or dies, so choose wisely.

Surge Deluxe (available now): One of the best genres for on-the-go gaming is the match-three puzzle, and this one's up there with the best of 'em. While most of these puzzle games will have you rotating colored blocks or columns, Surge Deluxe has you connect the colors with a current of electricity using the Vita's touch screen.

Limbo (available now): With giant spiders, pitch black environments, and instant death waiting for you at every step, Limbo's dark world is any child's worst nightmare. You guide a little boy through dangerous levels full of spiky traps and monsters that will impale, squash, and decapitate him with every misstep.

Mercenary Kings (available now): This is a throwback to the days of old-school, side-scrolling shooters, but with the modern trappings of progressive, RPG-esque leveling. Mercenary Kings is a heavily pixelated retro platformer that has you battling intense bosses, earning new equipment, and even crafting your own customizable guns. It's basically everything you could want in a modern Metal Slug-style shooter.

Batman: Arkham City (April 1 to May 6): The ever made available for free on PSN? Not anymore. But even if you missed the chance to get the game for free, it's totally worth throwing down the bills to face Batman's greatest adversaries in an open-world full of goons to pummel and comic book references to gawk at.

Stealth Inc: Clone in the Dark (available now): Platforming, stealth, and puzzles: if these gameplay elements are right up your alley, you definitely want to give Stealth Inc. a shot. A single mistake can mean instant death, but even if it takes you dozens of tries to dodge all of the lasers and killer robots in a test chamber, success is always rewarding.

Castle of Illusion: Starring Mickey Mouse (available now): If you missed out on the original 16-bit Castle of Illusion in the old days, here's your chance to play through the classic in all new, spiffed up visuals. Turns out, Mickey's quite the capable 2D platformer star.

Velocity Ultra (April 29 to May 27): Top-down shooters are a rarity these days; even rarer is a top-down shooter with slight puzzle elements built into it. Velocity Ultra isn't just the typical bullet hell shooter--you'll have to manage abilities that let you teleport through walls, and fling barrier-shattering bombs in an effort to rescue survivors spread across the levels.

PixelJunk Monsters: Ultimate HD (available now): Tower defense games are some of the you could possibly play. You'll build towers and fend off wave after wave of enemies like any other tower defense games, but once you get hooked, be warned. Time will fly.

Stealth Inc: A Clone in the Dark (available now): All of the stealth action and puzzle solving involved in getting your clone through the Stealth Inc. test chamber levels is also available on the portable PS Vita. And if you happen to have both a PS3 and a Vita you can cross play between the two versions of the game. Not a bad deal.

Dead Nation: Apocalypse Edition (March 4 to April 1): Take on zombie hordes with an arsenal of insane weapons, including machine guns, flamethrowers, and rifles that shoot bolts of lightning. The twin-stick shooter's Apocalypse Edition has enhanced visuals upgraded for the PS4 and includes the Road to Devastation DLC expansion.

Tomb Raider (March 4 to April 1): Lara is back and totally re-imagined. This time the heroine isn't the veteran that was in previous games; she's an inexperienced survivor trapped on an isolated island. All of the expected combat action and environmental puzzles are here and are arguably some of the best the series has seen.

Lone Survivor: The Director's Cut (available now): Every wonder what it would be like to wake up alone to the apocalypse? Well, this is it. Survive the post-apocalyptic world by scavenging for food, escaping dangerous mutants, and staving off insanity while you search for other survivors in this horrifying 2D adventure.

Thomas Was Alone (available now): Thomas Was Alone might just look like an early version of a soon-to-be complete game, but no--the characters are actually just cubes and rectangles. However, don't take that simple aesthetic for granted; by the end of this indie puzzle platformer, you might just feel more attached to that little mute block than most video game protagonists.

Lone Survivor: The Director's Cut (available now): Here's another title that benefits from Sony's cross play feature. You can try to survive the apocalypse on your home console or take your game with you on your PS Vita.

Thomas Was Alone (March 18 to May 20): Thanks to the wonders of Transfarring, Thomas Was Alone has the option to work with Sony's cross play feature. You don't just have to solve all those puzzles on your couch, you can actually bring your game with you on the go.

Unit 13 (March 18 to May 20): This third-person shooter puts you in the standard issue military boots of a spec-ops team as they fight terrorism all around the globe. Players take on missions with varying objectives under specified criteria--like staying hidden for the entire mission--for high scores and mission ranks.

Assassin's Creed is, put kindly, a contentious series. Put unkindly, its has had highs and lows so high and so low that I'm starting to feel seasick thinking about it. But for all its troubles, swathes of players keep coming back, because there's something at the heart of Assassin's Creed that still creates fun, enthralling, even timeless adventures.

Of course, no one can actually agree on which Creed games deserve that ‘timeless’ descriptor. If you're a newcomer to the series looking for what's worth your time, internet screaming matches aren't going to do you much good; you need a list of the best and worst of the Assassin's Creed series, free of drama. For you, I have combed through the data, consulted those most knowledgeable, and reached back into my own past to create a ranked list of all currently available Assassin's Creed games. This doesn't include AC games that have been scrubbed from existence, like the ill-fated Assassin's Creed Recollection, but everything else is here. Nothing is true, but everything is permitted, so permit me to say this list might spark debate.

This one was a tough call, because Freedom Cry was born as Assassin's Creed 4: Black Flag DLC, but had bigger ambitions and eventually became a . While its combat and sidequest structure make it all but inseparable from Black Flag, it deserves an honorable mention for its story alone. Here, former slave Adewale stands against the slavemasters of Haiti in the name of freedom, proving that the Assassins' mission can take on many important shapes.

Freedom Cry puts you in the thick of a slave trade and is unflinching in how it depicts that brutality. You can't miss the human auctions or runaway slaves who will be killed without your help, and being a participant rather than an observer makes it impossible to ignore. But perhaps most importantly, Freedom Cry shows how those slaves and the nation's freemen are active participants in their own liberation, working with Adewale rather than waiting passively. In that regard, Freedom Cry does something that is not only important, but almost entirely unique, and that deserves a shout out.

Before Ezio's trilogy was a twinkle in the eyes of the AC development team, there was Altair's Chronicles. The mobile prequel to the original Assassin's Creed, it sees Altair hunting for a mythical artifact called The Chalice in constricted 3D world. It's a disaster from start to finish: Assassin's Creed's combat is simplified down to the point that it's no longer interesting, locations and missions are same-y, its story (complete with forced romance) is hackneyed, and the dialogue is consistently awful with occasional forays into Vader ‘Noooooooo!’ territory.

The one thing Altair's Chronicles sort-of has going for it is visuals, including lovely (if overused) environmental designs, which at least make it aesthetically-pleasing. But that's not nearly enough to make up for its many and varied shortcomings, and with new mobile AC games surpassing its visual quality, it’s best to give this one a pass.

This actually covers five separate titles published over the years, but they're basically the same game, so it's efficient to talk about them all at once. Up until the release of AC4: Black Flag, every main entry in the series was accompanied by a mobile game that retells its story. Or, rather, takes that story and shaves it down to the absolute basics, using what remains as the skeleton for a simple side-scroller build for playing at the train station.

These games are workmanlike and handle well enough, but much of what makes the main games interesting is tossed out in the name of mobile consistency. Ultimately these titles feel like random side-scrollers with AC skins, and Ubisoft apparently thought so too: every sign of them has been scrubbed from the company's digital storefronts, so you'll have to hit the if (for some reason) you want to give them a try.

Assassin’s Creed Identity launched on iOS with the intent to be more like the full-blooded console releases, albeit with an RPG spin. Set in the Italian Renaissance, Identity attempts to recreate the series’ signature sneaking-and-stabbing gameplay, shrunken down for shorter sessions. Ezio’s been swept aside for custom-created characters, each brought to life using a marvelous Italian name generator.

Sadly, you’ll probably spend more time messing around with that than you will the actual game. It’s a free-to-play affair, sending you to and fro to eliminate some guy / collect this artifact / escort this person in exchange for skill points you can spend on outfits, equipment, and movesets. Spotty controls result in a lot of running into walls rather than up them, but at least you won’t have to avoid the usual swarm of civilians - there’s barely anyone in the streets, meaning that it’s up to the flat textures and boxy buildings to build the atmosphere. Bizarrely, Identity was only released in Australia and New Zealand on iOS; a promised Android version never arrived. Frankly, world, you’re not missing out.

If you only played the Assassin's Creed mobile games, you might get the idea that the series' trademark is side-scrolling your way through corridors of oblivious guards/corpses-to-be. Assassin's Creed 2: Discovery won’t do much to dispel that notion; you play as Ezio, conducting assassination missions for a series of clients, all of which are nondescript and ultimately unimportant. They just act as vehicles to push you into a 2D platformer that takes on a few infinite-runner qualities, if you feel like charging in full steam and destroying every barely competent guard you meet.

It's a simple game that doesn't have the depth of most Assassin's Creed titles, but it does accomplish what it sets out to do. Creating a smoother, teresting platforming experience than the mobile companion games, Discovery set the standard for 2D Creed games back in 2009. It's since been bypassed by the superior Chronicles: China, but might still be worth a play if you can find a DS copy, since Ubisoft has since removed all evidence of the mobile version.

Released alongside Assassin's Creed 2 and Discovery in a calculated assault on everyone's wallets, Bloodlines continues Altair's story following the events of the original game. As opposed to previous handheld/mobile entries in the series, Bloodlines tries to approximate the 3D look and free-for-all gameplay of the console releases. In the case of the former, it does a decent job, with crisp visuals that make it look like a true AC game. But when it comes to gameplay, Bloodlines misses the haystack: small environments funnel you into battles constantly, but the combat system doesn't actually use the PSP's controls to its benefit, so fights often feel as ungainly as hand-stitching in oven mitts.

Plus, while Bloodlines does have an involved story that's not as awful as Altair's Chronicles, it often falls flat and isn't strong enough to make up for the lackluster combat. Its one saving grace is Maria - Altair's sharp-tongued associate who fans might remember from a certain - whose interactions with Altair give the story some life and depth. Sadly, even she's not enough to save the production.

It takes serious confidence to slim down a mini-game from one of your previous titles and release it on its own. But Ubisoft was riding high on the crest of Black Flag's success in late 2013, and the result was Assassin's Creed Pirates, a mobile game that is just Black Flag's ship combat, playable on the go.

Pirates does try to be a proper Assassin's Creed game, with a story involving Assassins, Templars and magic DNA time machines, but that's just window dressing - you spend 99% of your time shooting cannonballs at other ships just 'cause. But the designers knew that, and so they made a point of prioritizing the combat and making sure that controlling ships via touch features feel simple and natural. Pirates sits low on this list because it’s just a facet of another Assassin's Creed game, but that facet is so well designed that it deserves recognition.

Assassin's Creed 3 is, in many ways, a test drive. It was the first Ezio-less Assassin's Creed in five years, the first set in a populated wilderness (fields in Italy don’t count), and the first to feature the series' now beloved ship combat. It does a lot of things right, creating a Frontier you can explore for hours, and it’s . Unfortunately, it gets a lot of other things - fundamental, obvious things - very wrong.

Main character Connor is often too aloof and superior to be sympathetic, and the amount of times he steps in to save the incompetent Founding Fathers is hard to take seriously. The game contains sections that emphasize stealth, but the actual stealth controls are poor, so these parts are far more annoying than fun. And, hurting from a tight development schedule, the game shipped with enough bugs to make an entomologist swoon; now the way it controls is awkward at best and game-breaking at worst. It has some good ideas, but ultimately can't execute on them; that's been left to later games that have the fundamentals down better.

AC Liberation still bears the marks of its time on the Vita. Its combat is just as fluid and satisfying as some of the strongest Assassin's Creed games, and presenting its story as the Templars' altered version of events is one of the most clever new mechanics the series has seen in a while. But there's no escaping how cramped the game feels, both in physical size and its storyline.

One-woman-wonder Aveline is a fascinating character with a lot of gusto, but her motivations are never really made clear, and neither are those of her enemies. And with only one city, some outlying swamp, and a temple to investigate, it doesn't make you want to explore the world the way an Assassin's Creed game should. All told, it fits squarely in the middle of the Creed quality scale: not great, but not terrible, and serviceable for fans in need of an AC fix.

If you got your first look at Assassin's Creed Rogue with no context, you might come away thinking it's Black Flag DLC. That isn't too far from the mark - the story of an Assassin-turned-Templar named Shay Cormac, Rogue focuses on the period of time between Black Flag and AC3, and lifts heavily from Black Flag's trove of assets. Ship combat is virtually the same, music and sound effects are extremely similar, and Shay fights the same way Edward does nearly stab for stab.

But with Black Flag's style of combat and exploration on the way out with the release of Unity, some fans hail Rogue as a welcome retread, and it does a standout job of replicating Black Flag's best parts. Plus, new environments like the North Pole, and minor additions to ship combat, give those mechanics a little extra juice without changing them too much, and seeing off some of the North American arc's most beloved characters is welcome fan-service. It doesn't do much new or inventive, but Rogue extends the life of a familiar and well-loved time-period, giving fans a soft place to land.

The game that started it all isn't looking as hot as it was eight years ago, but it isn't quite falling apart at the seams yet either. Effectively a tech demo for what the franchise could become, the original Assassin's Creed gives you one thing to do (assassinate, if you hadn't guessed) and tells you to do it ten times over, with only the most repetitive of sidequests to break things up. Much of what earned it acclaim at the time of its release has also faded, as graphics have gotten better and Ubisoft honed the controls for AC games so you don't run up walls quite as much.

But what the original Assassin's Creed has going for it is a place close to the series' heart: you learn everything you can about your target, you plot the assassination, and you execute. The high-profile missions offer some variety in that regard, since each target behaves in a unique way that favors a different kind of approach. It's bare-bones, and it's been done better since, but the game isn't irrelevant yet.

The latest in that fine tradition of Assassin's Creed side-scrollers, Chronicles: China perfects their best parts and improves on them by borrowing tricks from one of (hint: it's the one with the ninjas). Stealth mechanics are integrated seamlessly and give the gameplay a lot more flavor, and true free-running segments create intense and welcome action. Add in a beautiful art style that disguises its lesser budget, and Chronicles: China is easily the best among Assassin's Creed's not-quite-2D library.

On the downside, its short runtime and basic setup don't allow for the exploration of a truly great Assassin's Creed, and the lack of variety between environments means that the world quickly becomes repetitive. Plus, protagonist Shao Jun's revenge plot is light on heartfelt storytelling, and instead unapologetically replicates that of her mentor, Ezio Auditore. But it's a fun and challenging title that advances the quality of the series' smaller offerings and redeems the format.

Let's get this out in the open: Assassin's Creed Unity has problems. An ambitious project that promised to revamp Assassin's Creed's standard battle mechanics, create a bigger world than in any previous title, and build a completely new multiplayer from scratch, it bit off more cake than it could chew and was an . And while that may be the story that lives on into gaming infamy, it's not Unity's full story: it has a lot of good stuff under its lapel that isn't always buried by glitches.

In addition to being beautiful and upping the graphical standard for every Creed to come, Unity's assassination system is revolutionary, opening up new opportunities for creative killing by honing in on weak links in the environment's security. In addition, it offers up cerebral challenges in the form of murder mysteries and riddle solving, which are a lot tricate and interesting than AC has seen in the past. If all Unity ever brings to the series is the ability to and some serious brain teasers, its earned a place of esteem on this list.

Pick a popular game, and chances are good that the protagonist is somewhere between 15 and 35 years old. They might as well be dead after that, because you're more likely to run across a unicorn in-game than a silver-haired main character. Ezio Auditore is not only an exception to that rule, but the best, thanks to the brilliant story at the forefront of Assassin's Creed Revelations. Featuring easily one of the most thoughtful and mature tales the series has yet woven, Revelations set the standard for every Assassin's Creed story since.

Admittedly, that brilliance isn't felt in every part of the game. Constantinople is fairly drab and forgettable, and the tower-defense mini-game added to territory-claiming is basically the worst. But that only speaks to the strength of Revelations' narrative, which focuses on sacrifice and loss in a painfully honest way that satisfies your heart as much as it breaks it. Both Ezio and Altair get the loving send-offs they deserve, because Revelations knows that there's strength in telling a different kind of story.

Assassin's Creed Brotherhood sounds like a disaster waiting to happen. A direct, swiftly-produced sequel to Assassin's Creed 2 that restricts your movements to one city and deemphasizes story: it had shameless cash-in written all over it, especially given the precedence set by Altair's Chronicles and Bloodlines. But those of us who prepared for disappointment were met with a pleasant surprise: Brotherhood is good. So good that it changed the face of the series forever by implementing brand new mechanics that are still around to this day, like capturing territory, addictive multiplayer, and control over a legion of Assassins you can summon at your whim.

The only real downside to Brotherhood, as mentioned, is the lack of story and different locations to visit. But alongside those pieces of gameplay it executes so well, Brotherhood hides emotional slices of plot for the curious to find, and Rome itself is so diverse that you're never left wanting for much more.

Altair may have technically kicked off the Assassin's Creed franchise, but turning it into a gaming powerhouse that sells millions of copies to fans around the world? That was all Ezio, and for good reason. Starting from the very basic formula that started the series, Assassin's Creed 2 squeezed blood from a stone to create a nearly perfect game.

Its tale of revenge is engaging from the instant it begins, and full of characters you love and ache to see succeed. Assassinations are made much more complex and challenging through unique weapons and a new move-set that gets deeper the longer you test it out. It fills out the time between main missions with sidequests that are instantly engaging, and the best of them may . Nothing is overlooked, and nothing is wasted: AC2 is an expertly crafted and perfectly honed masterpiece, one that made Assassin's Creed what it is today. And for the longest time, nothing could surpass it.

While AC2 soared to success on an updraft of enthusiasm for a burgeoning series, Black Flag arrived on the heels of the disappointing AC3, when confidence in the series was at an all-time low. It faced a hostile climate with little faith that a game about pirate Assassins could possibly succeed. And in proper buccaneer fashion, it blew the doors right off the place, taking every piece of the Assassin's Creed franchise and turning it into pirate gold.

There's almost nothing about the Assassin's Creed series that Black Flag didn't either invent or radically improve; against all expectations, it offered up the biggest game world the franchise had yet seen, an incredible variety of addictive missions, ship combat that was suddenly fun, and an effortlessly beautiful soundtrack that you've probably listened to at least once while nowhere near the game. But Black Flag went beyond the video game basics, giving an honest treatment of an often misrepresented historical period, and deftly telling the tale of a time, a place, and a people that ultimately came to ruin. It's masterfully crafted, incredibly fun, and is the game that proves the series' best years aren't behind it.
