The parasites have taken over a space station orbiting Saturn. To neutralize the parasites on the station was sent a droid that can destroy the evil parasites, but to fulfill his mission, he needs the equipment preserved on the station.
During the game, you control a droid that collects parasites and neutralizes them with a neutralization kit. When the parasite is captured, the droid grows in size and some of its electronics fail. A droid can carry up to 5 parasites, otherwise it will die.
Take control of the droid and restore order!
