Though it's been out in the open for some time, Ubisoft today officially confirmed development was underway on TMNT: Smash Up. There are only two screens to date, featuring all four turtles doing their green-skinned, katana-wielding thang, but they look really promising (and possibly hint at a 2.5D game?).
The combination of '80s nostalgia (fun fact that we refuse to be embarrassed about: we had Turtles wallpaper right up until we moved out of home at 18) and the involvement of Super Smash Bros. Brawl developer Game Arts will ensure this game won't escape our attention easily. Check out both shots in Large-O-Vision here.
