Battletank, or Garry Kitchen's Battletank, is a 2D action game released for the Nintendo Entertainment System (NES). In Battletank, the player gets to control a tank from inside the driver's seat playing from a first-person perspective. You start each level with a set amount of ammo and fuel and must destroy all the enemies on each level before you run out of either. If you fire your machine gun for too long, it will overheat and cause you not to be able to fire again until it cools off.
