Teenage Mutant Ninja Turtles 1989 Classic Arcade

When you get into the same room as April, kill the Foot Soilders without being hit and then attack the boss. While attacking him make sure you dont stop hitting him until he falls or 4 times depending on how fast you can hit him. Once he falls back away and walk to the bottom of the screen. Hit him and go up and down since he cant shoot you unless your standing infront of him not attacking.
