The player is provided with a ship called the RVA-818 X-LAY, which is outfitted with two weapons: a primary weapon that fires straight lasers and increases in power when the player accumulates power-ups, and a secondary lock-on laser launcher, which can also be increased in power, that can target up to eight enemies at once by moving the targeting reticle.

The purpose of this computer is to govern the planet's environmental systems, verifying proper nutrients and care is provided to ensure the culture of humans and animal alike.

The best part about Galactic Attack, however, is that it offers everything a good space shooter should without any problems that may have shown up on a 16-bit system trying to do the same ... which means no slow down, even when a load of sprites are on the screen at once.

Although your ship is nothing to write home about, the enemies fly at you fast and furiously, giving your eyes a treat and your thumbs a workout.
