Platinum Games seem to be the go to developers for games lately, currently parts of the studio are hard at work on Star Fox Zero and the studio recently delivered the semi decent Transformers Devastation, and now it appears they hard at work with another game in collaboration with Bandai Namco. A classification found on the Australian Classification Board website has revealed that Platinum Games and Bandai Namco are currently working on a new Teenage Mutant Ninja Turtles game, the new game is set to be titled Teenage Mutant Ninja Turtles: Mutants in Manhattan and this is all we know. This new game is news to us all but we do know Platinum Games is making the game so it has a high chance of being really good and could be just about anything.
People have done so much with this franchise over the years but its rare we see a good game, but I think no matter what this turns out to be it is likely to have potential. I think we can rest assured we might hear something soon, perhaps at the upcoming Playstation Experience even.
