This level takes place in and below New York City.
The Hyperstone Heist is notable for being the only game to feature Rocksteady as an enemy character without his partner Bebop. The bosses includes Leatherhead, Rocksteady (having an attack pattern similar to the one that he had in the first arcade game), Tatsu (Shredder's right-hand man from the first two live-action films, who also appeared in TMNT: Manhattan Missions), Baxter Stockman (in his human form like in the first arcade game), Krang, and Super Shredder. There are a total of five stages ("New York City", "A Mysterious Ghost Ship", "Shredder's Hideout", "The Gauntlet", and "The Final Shell Shock"), which comprises a combination of new levels created specifically for this game and ones based on levels from the first arcade game and Turtles in Time. The controls are similar to Turtles in Time, but the ability to dash is now assigned to a specific button and the player can no longer throw enemies towards the screen. The gameplay of The Hyperstone Heist is heavily based on the second Ninja Turtles arcade game Turtles in Time, which was also released for the Super NES during the same year.
The Turtles have no choice but to go after Shredder and stop him. With the Hyperstone in his possession, he now has the power to take over the world. Shredder then hijacks the airwaves and announces to the world that this was only a demonstration of the power of the Hyperstone, the treasure of Dimension X.
