Deep Silver announces that Dead Island is gold, and that Techland's open-world zombie action game is now being reproduced for release in North America on September 6th and on September 9th in the rest of the world. Word is: "Only teamwork can get the four different protagonists of Dead Island through the seemingly insurmountable odds and dangers that await them on the zombie infested tropical island of Banoi. Their different skillsets complement each other and give them the ability to oppose the hordes of zombies that await them around every corner of the former holiday paradise." They also tout the game's "seamless co-op experience for up to four players with easy drop-in/drop-out mechanics throughout the whole game," and offer a new trailer (NSFW) showing off the game's co-op support. The trailer is also embedded below.
