Commander Keen

Commander Keen is the main character in a series of video games released by id Software during the early 1990s. The side-scrolling platformers were notable mainly for their use of EGA graphics, shareware distribution, and the future products of its developers. The Commander Keen games were distributed by Apogee Games.

Seven official Commander Keen games exist for the PC. They are:

Commander Keen in Invasion of the Vorticons

1. Marooned on Mars (first released on as shareware on December 14, 1990)

2. The Earth Explodes

3. Keen Must Die!

The Lost Episode

3.5 Keen Dreams

Commander Keen in Goodbye Galaxy!

4. The Secret of the Oracle (first released as shareware on December 15, 1991)

5. The Armageddon Machine

Commander Keen Special Edition

6. Aliens Ate My Babysitter

Some years after the above episodes, Activision released a new Commander Keen game for the GameBoy Color[?]. It was simply called Commander Keen.

The character popped up in a cameo in a secret level (number 32) of DOOM II, a later id product.

Commander Keen has also made cameo appearances in many other Apogee games, including Bio Menace[?], Paganitzu[?], and Crystal Caves[?].
