Summary: I bought the game because it had co-op modes allowing for 3 people to play at the same time and it was cheap. I didn't read any of the reviews prior to purchasing... I suppose I should have. The game was basically a button masher. We played it once and haven't yet revisited it. Honestly, I think it might be better used as a coaster than a game. Save your money and buy a different game.
Summary: I love that it's not serious at all! While I do love my more serious zombie or monster slaying games this one is a hoot. I particularly like the challenge levels when not in story mode. This was a good addition to my ps3 games!
