Teenage Mutant Ninja Turtles: Mutants in Manhattan, the next hack-and-slash action affair by Platinum Games (Bayonetta, Metal Gear Rising: Revengeance), will launch on 24th May for PS4, Xbox One,, PS3, Xbox 360, and PC.
The release date was revealed in a new trailer exclusive to IGN (but embedded below). As you can see, plenty of new bosses are prominently displayed like Bebop, Rocksteady, Krang, Armaggon, Karai, and a brief tease of Super Shredder.
Prior to this Platinum collaborated with Activision on a couple of other cartoon series spin-offs including the The Legend of Korra and Transformers Devastation. The former may have been somewhat lackluster, but the latter was worth a recommendation.
