In one of the most popular platform games of all time, you play Billy Blaze, the intrepid Commander Keen, who has built a space ship and flown to Mars to stop a Vorticon invasion. You get a gun and can find a pogo stick to help you make your way through levels with a number of different aliens, some of which are friendly. Suitable for all ages, this game has universal appeal. Originally there was a cutscene in which a Vorticon is seen stealing parts from Commander Keen''s ship, but this was cut from the final version. It can be seen in the beta version. There are 3 episodes in this game, with only the first episode playable in the shareware version.
Episode 1 - Marooned on Mars
Episode 2 - The Earth Explodes
Episode 3 - Keen Must Die
