Its out, is it for the pc or the xbox 360 that you are talking about, or are you bull crapping. The demo was released on Xbox live tonight, it's taking a while to download as so many people are doing the same thing.
Even though I'm really excited for this game I'm quite skeptical on how it's going to turn out. It's being developed by The Collective (Marc Ecko's: Getting Up) so I'll have to wait for more info to see how it's turning out.
There's five more chapters in the pc version as well as the game running at 60 fps. I really hope they release all the new content from the pc on the 360 as DLC.
