Dead Space Zero-G dev diary is disorienting

In the latest Dead Space developer diary, the developers at EA talk about the implementation of zero gravity environments. According to the video, "at least 20%" of Dead Space takes place in zero gravity. In zero gravity players use magnetic boots that allow Isaac, the game's protagonist, to stick to different surfaces. Players can also launch themselves to -- and subsequently walk on -- other surfaces in a room.

The developers mention that part of the game's challenge is becoming reoriented to your surroundings in zero gravity. As "the floor maybe become the ceiling, and the ceiling the floor," players need to reorient themselves quickly in order to deal with enemies. One last thing: in complete vacuums (where sound does not travel) players will only be able to hear the sounds of Isaac's breathing and heartbeat. Creepy.
