Teenage Mutant Ninja Turtles II: The Arcade Game is a game released for the Nintendo Entertainment System based on the popular television animated series Teenage Mutant Ninja Turtles. It was developed by Konami and published by Ultra. It was originally released as a coin-op arcade game, but later ported to the NES with a few extra levels. It is the sequel to Teenage Mutant Ninja Turtles but is entirely a side-scrolling "beat 'em up" game, whereas the first game was an action-adventure game.
