Dr. Michail Rasarow is suffering from an unknown disease, and his only hope rests on your mission: you'll be miniaturised and injected into his body to manoeuvre a specially designed craft. Pilot the craft through Dr. Rasarow's body; in game terms you must traverse through 50 levels in campaign mode, and take out 30 different kinds of viruses plagueing the good doctor's body.
