It seems that Dead Space has been around a lot longer than we'd have thought, originally taking form on the original Xbox. You can check out some early footage from the game in a video found after the break. There's not a whole lot to see really; it's very dark footage. What you can see looks very much like the Dead Space we know and love. Still, it's always interesting to see a game concept's humble beginnings. Plus, it might give us an indication as to what to expect from the Wii version.
