The Mother Creature of the planet Rooskee (fueled by irradiated Vodka) has turned helpless slaves into Communist Mutants From Space, and has launched an attack against your home planet. Wave after wave of mutants will continue to swarm and attack unless you fight back.
The attackers begin as mutant eggs, but soon hatch into evil creatures bent on destruction. Use your anti-mutant cannons to blast away at the invaders and see if you can destroy the Mother Creature herself. Game variations include multiplayer selection, adjustable difficulty levels, shields, time warp, penetrating missiles, steerable missiles, and a high score indicator.
