It seems that Platinum Games might be making a game based on the Teenage Mutant Ninja Turtles brand.
That's a listing from the Australian Classification Board is to be believed.
According to the ACB, the game is called Teenage Mutant Ninja Turtles: Mutants in Manhattan, it is multi-platform and being published by Activision.
This continues what seems to be a very busy period for the Japanese developer. Platinum is helping make Star Fox Zero on the Wii U for Nintendo, Xbox One-exclusive Scalebound for Microsoft as well as Square's PS4 and Xbox One title Nier: Automata.
