The Teenage Mutant Ninja Turtles are partnering with Ubisoft to celebrate their 25th Anniversary with a brand new game - Teenage Mutant Ninja Turtles: Smash-Up. This is the first Ninja Turtles video game that is not directly tied to a movie, television show or comic book. The 4-player action brawler features a variety of battle modes including online multiplayer gameplay, minigames, and an original story mode for single player co-created with Peter Laird. The game is developed for the Wii system from Nintendo by Game Arts - part of the team who worked on Super Smash Bros. Brawl. While similar to their past project, Smash-Up offers some new surprises and features for a new shell-raising experience. Throughout the game, fans will be treated to unlockable surprises celebrating 25 years of Turtle history.
