this looks like it could be good, I love any game with multiplayer, especially co-op. Here you have 4 guys each with different abilitys that you can play with. friends on split screen or XBL can join or leave at any time. The aliens theme is a good place and this game is supposed to have a nice mix of Suspense, horror, and action.

I’m generally not a fan of sci-fi but this game does look/sound promising.  I’m definitely very interested.
