"Dead Island publisher Deep Silver has announced Dead Island Riptide, a new entry in the undead franchise. Right now details are virtually non-existent. Deep Silver has only announced that original Dead Island developer Techland is in "full development" on the title for consoles and PC. Deep Silver stated that an "extensive reveal" of the title will take place later this summer. For now it seems like the publisher just didn't want to be left out of this week's E3 action."
