Teenage Mutant Ninja Turtles: The HyperStone Heist

Teenage Mutant Ninja Turtles: The Hyperstone Heist, released in Europe as Teenage Mutant Hero Turtles: The Hyperstone Heist and in Japan as Teenage Mutant Ninja Turtles: Return of the Shredder is a side-scrolling beat 'em up based on the Teenage Mutant Ninja Turtles (TMNT) franchise, and was also the first TMNT game released for the Sega Mega Drive/Genesis.

April O'Neil is reporting from Ellis Island when, in a sudden flash of light, her audience and herself witness Manhattan Island suddenly starting to shrink. 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. With the Hyperstone in his possession, he now has the power to take over the world. The Turtles have no choice but to go after Shredder and stop him.

The gameplay of The Hyperstone Heist is heavily based on the second TMNT arcade game, Turtles in Time, which was ported to the Super NES during the same year. The controls are similar to Turtles in Time, but the ability to dash is assigned to a specific button and the player can't throw enemies towards the screen. The game shares nearly the same soundtrack and sound effects as Turtles in Time, but the music plays faster in The Hyperstone Heist. Though there are less than half as many levels as Turtles in Time, each level is longer. Furthermore, The Hyperstone Heist has a more aggressive enemy AI and faster-moving gameplay.

There are a total of five levels ('New York City', 'A Mysterious Ghost Ship', 'Shredder's Hideout', 'The Gauntlet', and 'The Final Shell Shock'), which comprise 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 bosses include Leatherhead, Rocksteady, Tatsu, Baxter Stockman, Krang, and Super Shredder.
