The player must use an 8-way joystick to pilot a combat aircraft called a Solvalou, which is armed with a forward-firing Zapper for aerial targets and a Blaster which fires an unlimited supply of air-to-surface bombs for ground targets.
How to Play
There are various aerial enemy aircraft which fire relatively slow-moving bullets at the player, as well as fast-moving projectiles and exploding black spheres. Ground enemies are a combination of stationary bases and moving vehicles, most of which also fire slow-moving bullets at the player. Giant floating Andor Genesis motherships appear in certain areas; these must be defeated by knocking out their cores, and are considered one of the first level bosses to be incorporated into a video game.
