Rebel Moon Defense is a fast-playing game for two, inspired by the Tower Defense genre. The imperials have discovered the last rebel outpost on a moon colony surrounded by an asteroid belt, and launched a devastating Chaos Bomb to destroy it. The bomb appears at a nearby star gate and heads straight for the base, but the rebels have had time to place automated weapons and booby traps on some of the asteroids. Will the Chaos Bomb reach the moon and annihilate the rebels? Or can they destroy it and evacuate their base?
