I might be the only one that cares, but the achievements leaked for Mutants in Manhattan. Couple things to note is it seems to be open world, turtle switching is a thing as well as co-op, and it may not exclusively be the IDW continuity since Wingnut appears in a dedicated stage.
That'd definitely be cool. So far the confirmed villains just based on achievements are Shredder, Karai, Slash, Krang, Wingnut, and Bebop & Rocksteady who may actually be secret bosses since their icon appears in the "defeat a secret boss" one.
What. How is that Wingnut was choisen out of all of them?
I mean all of those are pretty standard and expected. I really hope we get more surprises like Wingnut, Armaggon, War, Rat King would be pretty cool too.
