In Teenage Mutant Ninja Turtles: Legends, players must help Leonardo save his brothers and fellow mutants from the Kraang army. The evil overlord Kraang Prime has kidnapped mutants, including the Ninja Turtles, for their DNA to create an army of Ultra Mutants. With his brothers pulled through a Kraang Dimension X portal, Leonardo must recruit allies and foes alike to stop the nefarious plan. Players can explore the Turtles universe with an all-new original story, battle through seven chapters and over 70 stages, and take on bosses like Shredder and Kraang.

Players can collect and level up over 30 TMNT characters, train them to learn their super sweet moves, and build their Turtle-rrific team. They can also fight against the Kraang in the Ninja Turtles’ favorite locations from the TV show, including Dimension X, the sewers, and the classic New York City rooftops. For the first time, players can fight the Kraang as a Ninja Turtle friend or foe, collecting and playing as Tiger Claw, Rocksteady, Bebop, and more. They can create strategic teams and take on the Kraang.
