So apparently this week is "Preview Dead Space Week" at the major game sites.

That's definitely the case with Dead Space, EA's upcoming survival horror title set in the claustrophobic corridors of the USG Ishimura. We've followed the title for a while now, tracking the details of the doomed vessel and Isaac Clarke's struggle for survival, but we only recently had a chance to check out a preview build of the game, which provided us with a taste of what gamers will experience in early October.

As space miner Isaac Clarke, you're aboard the Nishimura, a massive mining ship that's gone AWOL and offline. Naturally, after you board the ship with fellow employees, things go decidedly pear-shaped.

The game is being developed internally at EA and has been making us jump since we got our first look some months ago. We finally got our hands on a work-in-progress version of the game for the Xbox 360 to see how the various demos we've seen all fit together.
