How do you keep a game universe fresh the second time around? Add functionality. DS2 will let you use severed limbs and objects in the environment to impale Necromorphs, word to Madworld. The game's zero-gravity system has also been overhauled to allow Isaac free movement in any direction. Decompression also factors in; as we learned from Total Recall, a lack of atmosphere can be a real bitch—and in Dead Space 2, you'll be able to shoot out windows in certain areas so that enemies get sucked out into space like so many Schwarzenegger eyeballs.
