Timed to celebrate 25 years of comics, cartoons, movies, toys, and video games, Teenage Mutant Ninja Turtles: Smash-Up is a fighting game designed to give the franchise the full super Smash Bros. treatment, complete with environmental attacks, eight-player battles, and a large roster of fighters. Players can select from more than 15 characters, including series mainstays Michaelangelo, Leonardo, Raphael, Donatello, Splinter, and Shredder, as well as a few characters from outside of the "Turtle" universe, such as publisher Ubisoft's unofficial mascot, Raving Rabbid. Each character has a unique fighting style, and gamers can also unleash projectiles and special ninja powers, such as fire, lightning, tornados, and earthquakes. The game makes use of detailed backgrounds and a 2.5D perspective, giving depth and interactivity to more than a dozen trap-filled stages. "Arcade" mode serves as the primary single-player feature, though solo gamers can also participate in "Battle Royale" and "Survival" modes, as well as the mini-game-filled "Mission Mode." Multiplayer fans can join up to seven friends for "Swap Out" and "Tournament" modes, or head online for one-on-one action.
