I haven't played it, but I am dissapointed there is no blood in it. Not because I want the game to be for "hardcore adult gamers", but because it adds a sense of realism and adds to the mechanics of gameplay, which I think pulls you more into the game.
I like it, i'm not that far in it, but i's fun. Like everyone has said, definitely rent it 1st, you don't want to waste $50 for nothing. The one problem I have is when i'm turning, it always points up at the ceiling while i turn. Anyone have any tips?
