Deep Silver have announced a sequel to one of last year's greatest co-op games, Dead Island. The new game is called Dead Island Riptide and it's in development for PC and consoles by TechLand. Other than that we have absolutely no other details about the game, but the publisher promises a lot more details this summer. We're guessing the big reveal will be at Gamescom in Germany later this year. Obviously because of the late reveal, don't expect the game to be available this year, but instead move it into an already crowded 2013.
