[1][2] Players guide a ship through deep space while encountering spherical objects that appear to look like a bunch of comets or shooting stars.

They suddenly shapeshift into large creatures called Firebirds as the player gets closer to them and start attacking the ship in ever more complex looping formations.

As a Space Ship Commander, players must seek out and destroy three kinds of Firebirds in three missions.

To avoid this from happening, players must destroy the bomb from directly beneath it before it crashes.

Besides shooting missiles, the main ship also uses the warp mode that can only be used once in every level to escape impending danger and/or to strike out at a flock of birdlike creatures.
