Dead Island has sold 5,000,000 copies. By my math that's like, a gillion double-dead zombies. I don't know how many severed limbs that would be. All of them? Obviously Deep Silver is very pleased so much so that they sent out a press release patting themselves on the back. I would too. Dead Island is a damn fine cooperative zombie survival game. It earned our Editor's Choice award in our Co-Op Review.
