At a panel at PAX, Viscearl Games gave a quick look at Dead Space 2. While it isn’t much, it does show off the new jet pack and a train environment.
The footage is off screen, so it is difficult to tell how it compares to the first game visually. But any footage is better then no footage.
You can check out the video after the jump. It takes a few seconds to start, but the wait isn’t too terribly long.
