Teenage Mutant Ninja Turtles: Turtles in Time, released as Teenage Mutant Hero Turtles: Turtles in Time in Europe, is an arcade video game produced by Konami. A sequel to the original Teenage Mutant Ninja Turtles (TMNT) arcade game, it is a scrolling beat 'em up based mainly on the 1987 TMNT animated series. Originally an arcade game, Turtles in Time was ported to the Super Nintendo Entertainment System in 1992, whereupon it was retitled to serve as a sequel to Teenage Mutant Ninja Turtles III: The Manhattan Project. That same year, a game that borrowed many elements, Teenage Mutant Ninja Turtles: The Hyperstone Heist was released for the Sega Mega Drive/Genesis.
Years later, the arcade version of Turtles in Time was revisited on newer consoles. A slightly altered version of the arcade game was included as an unlockable bonus in the 2005 game Teenage Mutant Ninja Turtles 3: Mutant Nightmare. In August 2009, Ubisoft released a 3D remake of the game, Teenage Mutant Ninja Turtles: Turtles in Time Re-Shelled, for Xbox Live Arcade. The remake was released onto PlayStation Network on September 10, 2009.
