This short sequence from Dead Space 2 was shown at the end of the game's time during EA's GamesCom press conference. That small, blurry footage, however, didn't do the insanity justice.
Here it is in a proper clip, where you can truly appreciate what's happening. You are being shot through space, through destroyed buildings, so that you land on top of a city floating sideways. In space.
You wouldn't think you could "fall" in zero-gravity, but that's exactly the sensation on offer here.
