the tank is controlled by a standard nes controller: directional buttons control the tank's movement, "a" fires the tank's machine-gun, "b" fires the main gun, "start" pauses the game on the main screen, and "select" opens the in-game menu. the turret can point in the standard 8 directions and is rotated by simultaneously pressing "a" and the desired direction. the turret will maintain its direction on the screen regardless of the tank's movements or facing and using this is part of the game's strategy.
