Someone could use a bath.

We've heard details about "guided first-person experience" Dead Space: Extraction, but so far not all that much in the way of actual gameplay footage outside of the game's teaser trailer a while back. Lucky day then, because a video walkthrough of the E3 demo has hit the intarnets, along with the game's control scheme and release dates for North America and Europe.

The demo lasts about 18 minutes and reveals a few game mechanics, like an active reload system that seems to be vital to master if you want to keep your digits attached. The HUD is sparse but doesn't seem too complicated, and the new weapon, the Arc Welder, shows off it's electric glory. While it's only the first level, there's a definite Umbrella Chronicles-in-space vibe going on, instead of more traditional lightgun fare like House of the Dead: Overkill. If that's your cup of tea, you'll certainly dig this one.

Extraction will be released nigh-simultaneously in North America and Europe, on Sept. 29 and Oct. 2 respectively. Telekinetically click your way over to IGN for the full demo, and check out the game's control scheme below, courtesy of LiveGen via GoNintendo:
