Your initial goal is to rescue the fair maiden, April, but your ultimate objective is to battle through the streets and sewers of New York until you score a victory at the TECHNODROME, home of the evil Shredder and his Life Transformer Gun. Once a turtle is captured, he is out of action until you find and rescue him. (When you loose all four turtles, the game is over.) At the end of each level you'll unfortunately find a Karate Boss who is anxiously waiting to turn you into turtle soup.
