To do this, the player takes control of a small space fighter and destroys enemy space craft on top of vertical scrolling backgrounds. The ship can carry up to two different weapons systems. In total there are four different weapons: Green Flash, Blue Blizzard, Bomber and Power Cannon.
After successfully completing the moons of Apano Sin in arbitrary order, the player faces the final level on the planet itself. One unusual feature for a shoot 'em up is that enemy patterns are randomized, so that they can't be learned by heart.
