Dead Space 3 (Demo)

Platform: iOS
Price: Free

Congrats, 360 owners! You get to try out Dead Space 3 a week before anyone else (at least if you like the official page on Facebook). Isaac exploring the blood-soaked winter wonderland of Tau Valantis looks promising enough, though the really interesting (and almost completely ignored) aspect of the game is that when not playing in co-op the PTSD-stricken engineer apparently talks with his fractured psyche. Sold.
