Keen 1 Story
Commander Keen: Marooned on Mars is the first episode in the Commander Keen games. In this episode, aliens from the planet Vorticon VI find out about the eight-year-old genius and plan his destruction. While Keen is out exploring the mountains of Mars, the Vorticons steal vital parts of his ship and take them to distant Martian cities! The four parts are the Joystick (for manual flight control), the Car Battery (for electrical systems power), the Vacuum Cleaner (reworked as an ion propulsion unit) and the Everclear (alcohol for fuel) — see Bean-with-Bacon Megarocket for details. Keen must explore the planet, fight the Martians and their Butler Robots and Tank Robots, find the members of this Vorticon outpost and wrest the parts back from their wicked, clawed hands!
