Aside from the inclusion of multiplayer, probably the biggest addition to Dead Space 2 is "The Sprawl", the confined, segmented sections of the first game's spaceship replaced with the cavernous interior of a space station.
That's a lot of ground for our hero Isaac Clarke to cover, so you can excuse him for popping the helmet off and taking a breather! After all, if you were going to spend a bunch of time doing nothing but running around a space station in the dark shooting monsters and crapping your pants, you'd need to take five every now and again too.
Horror game Dead Space 2 will be out on Xbox 360, PC and PS3 on January 25, 2011.
