At this point, it's no secret 343 Industries is making some significant changes to the formula of Microsoft's prized sci-fi franchise with Halo 5: Guardians. A public multiplayer beta ran through January, and the studio has been quite forthcoming on what to expect from its competitive offerings. I'm ashamed to admit I was late to the party, as it wasn't until this morning at PAX East that I finally got some hands-on time with the game at Microsoft's booth.
