Even the most virtuous saint can have a sinister streak. The important part is whether or not you actually act on those dark impulses. That's one of the things that make video games so interesting - you can have fun exploring your meaner instincts without worrying about hurting anyone, going to jail, or destroying anything important. But just because you're in a safe, digital environment, doesn't mean that there aren't any consequences to your actions.

Even when games give you carte blanche to run wild and destroy everything, there's still a good chance that the developers have snuck in some kind of morality to, erm, 'nudge' you in the right direction. Whether that means sending an army after your to punish you for your transgressions or just killing you outright, these games make a point to teach you a lesson for your evil, evil ways.

This is classic video game punishment that still has the power to mentally scar anyone who dares attempt it. Attacking those innocent, feathery Cuccos that appear throughout Hyrule will cause them to swarm after you in a frenzied rage, and the only way to get them to stop is to leave the current area. It's a staple of the series, appearing in games like A Link to the Past, Ocarina of Time, and even spin-offs like Hyrule Warriors. Luckily, one or two hits won't set them off - you have to be incredibly deliberate in your quest to draw their ire.

Samus Aran may not talk a lot, but she's generally considered a good, kind-hearted person, always showing up to save the day when duty (or a few dollars) calls. But Metroid Prime 3 lets you take a few potshots at one of its few NPCs milling about near the beginning. You can't actually hurt them, but if you keep it up, a little turret drops down to defend them from your senseless aggression. Blow that turret up, and another, stronger one drops down to replace it. Destroy that one, and an even bigger turret shows up, and .

Shadow Warrior takes the "retribution against animal cruelty" to a whole new level. Most of the creatures you can eviscerate in the 2013 reboot deserve it, as the only thing that doesn't want to kill you outright are some bunnies you'll see milling about and… *ahem* getting amorous with each other. Try to interrupt their lovemaking by shooting them, however, and suddenly these innocent rabbits start hunting you down with lightning-quick speed while heavy metal blares in the background. Lesson learned.

No one likes a team killer, but Conker's Bad Fur Day's will actually call you out on your indiscretions. Take out too many of your own teammates, and you'll be branded a traitor. Soon, you'll find that there's nowhere to hide, as your AI compatriots will hunt you down until someone finally kills you. The final insult comes as they shout things like "Fucking traitor!" as they pump you full of lead.

The Badi Dea (say it fast) is a Star Destroyer that originally showed up in the classic space-sim X-Wing. The name is a hint; you're supposed to run away from this behemoth as fast as you possibly can, before it and its endless waves of fighters shred your ship to bits. But in the semi-sequel TIE Fighter, the Badi Dea is one of your allies - unless you decide to take out one of the ships you're supposed to be protecting. Apparently, the Empire considers this to be treason (with good reason), and sends the Badi Dea after you. It won't stop until you've been pounded into so much space dust.

Many games don't like it when you attack animals with wanton cruelty, but Metal Gear Solid 2 is one of the few to actually try to make you feel really guilty about it. Once you first climb out of the depths of the Big Shell and into the sunlight, you'll notice that the sky is filled with seagulls - who are more than willing to take a crap on you if you stand in one place for too long. If you spend too much time getting revenge by shooting them out of the sky, you'll get a call from the Colonel and your girlfriend Rose, asking you, in so many words, "What the hell do you think you're doing?" You can't even save your game until you apologize to Rose. You know what you did.

Half of the fun of those old King's Quest games was trying to outsmart the text parser by typing in random stuff and seeing if the game would do something with it. In some situations, it actually would - usually with hilarious results. If you walk into the church in King's Quest 2 and , the game actually throws up its hands in disgust. "Anyone who would kill a man of the cloth doesn't deserve to play this game. Therefore, we will end it," the game reads, promptly killing you dead on the spot. A simple "no" would have sufficed.

With being surgically constructed as we type, there's rarely been a better time to return to Eidos Montreal's triumphant first attempt to augment the classic series for a new generation. Not least because there's so much you probably missed first time around.

Deus Ex: Human Revolution is so dense that it’s ripe for in-jokes, and Lead Narrative Designer Mary DeMarle, writer James Swallow and Art Director Jonathan Jacques-Belletete didn’t disappoint when we begged for enlightenment…

.

A part that didn’t make the final cut was on the top tier of Hengsha. “Man, you should have seen the architecture we had. And the view!” says Jonathan Jacques-Belletete. “We had a look-out spot where you saw the eco city all the way across, with its layered districts influenced by rice paddies, and the Tai Yong Medical skyscraper monolithically standing in the middle of it all. All that with a humongous sun burning your eyes...”

In FEMA, a pocket secretary provides the names of Eidos Montreal employees that have been added to the ADEX list – troublemakers who should be rounded up and imprisoned. Meanwhile in Detroit, Detective Frank McCann and Officer Champagne are both named after designers, while Audio Director Steve Szczepkowski works at the local LIMB clinic.

The colour yellow gets quite an outing in DX:HR, so much so that the art team decided to leave multiple buckets of yellow paint in the game’s corridors and construction zones.

Nods to the original Deus Ex game abound in DX:HR – on news broadcast ticker-tape you could read predictions about everything from the earthquake that would sink California to mentions of the original’s famous lemon-lime fizzy pop. “Probably one of the most memorable for me,” adds Mary DeMarle, “is the diatribe that’s being delivered by a hobo ‘doomsayer’ during the Detroit riots. He’s trying to warn people about the danger posed by the Illuminati and pretty much predicts the coming of the Grey Death.”

Final Fantasy XXVII can be seen throughout the game, first added in the very week that Eidos was acquired by Square Enix. “You have no idea how serious the whole affair got!” laughs Jonathan Jacques-Belletete. “It went to the highest echelons of Square Enix’s hierarchy to get it approved for inclusion in the game.”

The most secretive email exchange in DX:HR is in a mini-storage unit in Hengsha – and it’s that of a hacker who recorded the opening conspirator conference. He’s also responsible for every Nigerian scam email in the game. “The last mail on his computer is an automated failure report from the program he created to send out these mails,” says Mary DeMarle. “It lists where every Nigerian email can be found. I love this mail especially, because it was written for me by one of the programmers!”

Meetings are good for something. “The first cutscene I wrote, I did to kill time while waiting for a meeting to finish,” James Swallow reveals. “It was used, almost totally unchanged, as the final scene in the game. Stay to the end of the credits, kids.”
