For those who never heard about it, it's a game where you are a convict and are transported to a facility when it becomes infested with zombie things. Its basically a aim, shoot, reload type game but it is really addictive. You are basically looking for a way out but there are a lot of those things around and they will sometimes come out of no where or throw their heads at you.
I don't dare play it for the fear of getting traumatized by that game. I do adore Ouendan and Elite Beat Agents, though.
