The game starts with the top screen showing a view of outer space. On the bottom screen, players choose one of three giant flying robots to battle the enemy. The game then switches to show a radarscope up top and the battle on the bottom. Use a tap of the stylus to lock onto the enemy circles. Once all three are locked, players select a weapon to destroy them. The game then transforms into a series of stylized anime movie clips as the robot fires at the enemies.
