Forget the tantalizing leaks ; now it's official.

Over the past month, we've been hearing more about the latest from Platinum Games, a Teenage Mutant Ninja Turtles title supposedly in the works for multiple platforms. For instance, we got concept art and the achievement list .

Now, publisher Activision has formally unveiled Teenage Mutant Ninja Turtles: Mutants in Manhattan , in development at Bayonetta and Vanquish studio Platinum. To celebrate the announcement, we got a radical new trailer that features the iconic TMNT villain, Shredder. The story appears to focus on the Foot Clan's first assault on New York City, and we also get a peek at other bad dudes like Bebop and Rocksteady.

Mutants in Manhattan will land this summer for PlayStation 4, PlayStation 3, Xbox One, Xbox 360 and PC.
