Ubisoft and the creators of Super Smash Bros. Brawl (some of whom worked on Dead or Alive) came together to create Teenage Mutant Ninja Turtles: Smash-Up (TMNT: Smash-Up for short), a fighting game based in the Turtles’ universe. It’s coming to Wii in September 2009.
The 7 characters unveiled so far are: Leonardo, Donatello, Michelangelo, Raphael, Splinter, April, and Shredder.
More stuff like the different modes (4-player online multiplayer, single player and versus), characters, stages, powerups, and controller options, will be unveiled at Comic-Con 2009 in July.
