Teenage Mutant Ninja Turtles, released as Teenage Mutant Hero Turtles in Europe, and Gekikame Ninja Den (激亀忍者伝?, "Fierce Turtle Ninja Legend") in Japan, is a 1989 platform game for the Nintendo Entertainment System. The game was developed by Konami and originally released in Japan through Konami themselves, then in North America through Konami's Ultra Games imprint, followed by a release through the European equivalent, Palcom Software, in PAL regions.
This was the first Teenage Mutant Ninja Turtles video game, and is based on the 1987 TV series, which was in its third season at the time of the game's original release, although the art style more resembles the original comic series. The game was ported to various home computer platforms in 1990; the original NES version was ported to Nintendo's PlayChoice-10 arcade system in 1991, and the Wii's Virtual Console service in 2007. It was taken off theWii Shop Channel on January 26, 2012.
