Teenage Mutant Ninja Turtles III: The Manhattan Project

Teenage Mutant Ninja Turtles III: The Manhattan Project (or Teenage Mutant Ninja Turtles 2: The Manhattan Project in Japan) is a beat'em up game based on the 1987 TV series developed by Konami in 1991 exclusively for the Nintendo Entertainment System. It is the sequel to the NES port of the original arcade game.

Plot
The Ninja Turtles are on vacation, which is promptly ruined by Shredder, who, in addition to kidnapping April O'Neil, steals the entire island of Manhattan. It's up to the Ninja Turtles to stop Shredder and return Manhattan back to its place.

Why it Rocks

 * 1) Gameplay is very similar to the original arcade game.
 * 2) The graphics are great for NES standards, and they've been improved from the second game.
 * 3) Once again, the music is pretty good.
 * 4) Lots of bosses, ranging from iconic characters like Leatherhead, Bebop and Rocksteady, to more obscure characters like Groundchuck and Dirtbag.
 * 5) Assuming the player has several lives left, they can choose to play as another Ninja Turtle if they die instead of being stuck with one Ninja Turtle for the whole playthrough.

Bad Qualities

 * 1) No 4-player mode, though this can be excused due to the limitations of the NES.
 * 2) Some of the bosses are pretty hard, especially Tokka.
 * 3) It never released in europe at all, despite heavy promotion.

Trivia

 * The music for the final boss, the Super Shredder, is taken straight from Turtles in Time.
