Phoenix is an outer space-themed fix shooter. Gameplay is somewhat predictable: each level has two types of alien birds that fire at your ship, and a mothership that is guarded by many of the same alien birds. The spaceship moves horizontally at the bottom of the screen. In addition to the missiles, the ship is equipped with a shield that can be used to zap any of the alien creatures that attempt to crash into the spaceship. However, the player cannot move while the shield is active, and must wait for a short period before using it again. Key up to activate the shield. Ctrl to shoot.
