This game is extremely limited in that it is played using only the paddle controller's fire button. You do not control the movement of the planes and helicopters, but rather you must time your shots to do the most damage.
The cartridge includes a secondary variation titled "Sea Bomber" that is a little more interactive. In this game, you deploy bombs onto seafaring ships, but this time you can use the paddle controller's knob to determine the depth of the bombs.
