Teenage Mutant Ninja Turtles: Teenage Mutant Ninja Turtles: Return to New York

Teenage Mutant Ninja Turtles: Return to New York is a rebalance and remaster to the original TMNT game released in 1989. Renowned for it's difficulty, inconsistent gameplay, and a very overpowered Donatello, the old game manual reveals a story loosely based on the 1980's cartoon "Shredder and Splintered," in which the Shredder has a retromutagen gun that could turn Splinter back to human, but also the TMNT back to normal turtles.

The main goal of this game is to give each turtle a different set of abilities to encourage use of the whole team in different situations throughout the game. Some gameplay elements have been added to facilitate this. Also, the story and setting of the game has been enhanced as much as possible.

Notable features include:

Known Bugs: - - - - - - - - - - - - - - - - - - - -
-SRAM doesn't work for stage 6. Seems to be an issue with the cowabunga SRAM base
-If you deal the final blow to shredder in the air AFTER he jumps AND one of his mutagen shots
is still on screen, his death animation will not start, your turtle will freeze, and you'll be
softlocked. This glitch appears to be present in the original as well, but it's frustrating
enough that it bears repeating here.
