Teenage Mutant Ninja Turtles 3: Mutant Nightmare is a video game published by Konami for the PlayStation 2, GameCube, Xbox, and Nintendo DS, based on Teenage Mutant Ninja Turtles 2003 TV series.
The game is divided into four sections, called "Episodes" (one is unlocked at the third Episode's conclusion): Space Invaders, dealing with the third season opening arcs Space Invaders and Worlds Collide; Bishop's Gambit, based on both the eponymous episode of the third season, and featuring antagonists from two other episodes; Exodus, detailing the events of New Blood and the Exodus two-parter; and finally The Nightmare, based on the five episodes in which Ultimate Drako separated the Turtles and Splinter across different dimensions.
After competing episode 1 in Teenage Mutant Ninja Turtles: 3 Mutant Nightmare, the player will unlock a slightly altered version of the arcade game, Teenage Mutant Ninja Turtles: Turtles in Time, which is an older video game in the series also made by Konami.
