Following numerous leaks, official and otherwise, PlatinumGames has debuted a trailer announcing "Teenage Mutant Ninja Turtles: Mutants in Manhattan."

Arriving this summer, the game pits Donatello, Leonardo, Michelangelo and Raphael against Shredder, the Foot clan, Bebop, Rocksteady and -- as the trailer shows -- the mutant shark Armaggon.

Here's the official description: "Battle alongside your brothers through the sewers, subways, and streets of NYC to take down Shredder and Krang's evil organization, Foot by Foot. Unleash custom combat skills and powerful team combos to save Manhattan from the overwhelming dark forces growing in the shadows."

Released by Activision, "Mutants in Manhattan" will feature four-player online cooperative play, comics-inspired art and a story penned by IDW Publishing writer Tom Waltz.

The game will be available for Xbox 360, Xbox One, PlayStation 3, PlayStation 4 and Windows PC.
