Demon Attack

Evil creatures from the Demon Armada are attacking Earth's last outpost on the Moon. Only your Laser Cannon stands between them and their conquest of the Earth! Ward off successive waves of demons in order to approach Pandemonium, the demon base, and challenge the demon leader. Outmaneuver Suicide Patrollers flying from the Core of Pandemonium. A direct shot to the demon leader destroys Pandemonium-but not for long!
