Only the quickest can survive in this super-fast 'zap-em' game requiring superior reflexes. The future of the galaxy is in your hands as the ruthless invaders from NGC 891 crash through the ionosphere.
Starting with just three lives, you must destroy each wave in turn. A life is lost if you are hit by the enemy fire or if the enemy manage to get past your craft. A bonus life is awarded every 100,000 points. Behind the last wave of enemy craft hides the mothership. This must be destroyed so that you may advance to the next level.
A hi-score table records the top eight scores.
