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 comic book characters the Teenage Mutant Ninja Turtles for the Sega Genesis.

Teenage Mutant Ninja Turtles IV: Turtles in Time, developed by Konami, is a side-scrolling beat ’em up for up to two players. It is the fourth game in the series, following Teenage Mutant Ninja Turtles III: The Manhattan Project on the Nintendo Entertainment System. Originally released as an arcade game, it was later ported to the Super Nintendo Entertainment System in 1992.

This version includes two new levels (the first part of Scene 3 and all of Scene 6), which feature new enemy characters, including two new bosses: Tora (a dog-like "blizzard beast") and Shogun (a robotic samurai), both characters created for the game. Most of the original stages from the arcade version were extended as well and the second half of Scene 3, the parking garage stage, replaces the arcade version's end battle with Bebop and Rocksteady with a battle against the mutated fly form of Baxter Stockman.

NOTE: This is the original 4-Player Arcade release, not the NES Title. The player chooses from one of the four Ninja Turtles: Leonardo, Michelangelo, Donatello, and Raphael. After Shredder kidnaps the Turtles' friend April O'Neil and their mentor Splinter, they must give chase, save their comrades, and defeat the evil Shredder. The player chooses from one of the four Ninja Turtles: Leonardo, Michelangelo, Donatello, and Raphael. Depending on the version of the game, the characters are either, chosen at the start of the game or assigned by control panel. After Shredder kidnaps the Turtles' friend April O'Neil and their mentor Splinter, they must give chase, save their comrades, and defeat the evil Shredder. Up to four players (two in some versions) can take control of any of the Turtles. Donatello has slower attacks but a longer range, Michelangelo and Raphael have faster attacks but a shorter range, and Leonardo is a well-rounded Turtle with average range and speed. The eight-way joystick controls the movements of the Turtle, the jump button makes them jump and the attack button makes them hit in front of them using their weapon. In addition to this, some combinations are possible. The Turtles can throw Foot soldiers overhead, and by pressing the jump and attack buttons, a special attack is performed. Raphael rolls along the ground and finishes with a kick, while the other Turtles do a sweeping jump attack with their weapons. Turtles can also spring off the wall in certain areas. Enemies can be defeated more quickly by slamming them into walls or solid objects. Many objects such as traffic cones, parking meters, fire hydrants and exploding oil drums can be hit or damaged with attacks in order to help defeat nearby enemies. In the attract mode, the game showed the first part of the cartoon opening, along with a portion of the Teenage Mutant Ninja Turtles theme song. Most of the enemies the Turtles face are the Foot Soldiers, all color-coded to indicate their attack patterns and weapon of choices. Some enemies, such as the standard purple-clad Foot Soldiers and Roadkill Rodney robots, have the ability to restrain the Turtles' mobility and drain their health, leaving the player open to attack for other enemies. The bosses in the game include Rocksteady and Bebop (individually at first in that order, and later the two of them together), Baxter Stockman, Granitor, General Traag, Krang, and Shredder himself.
