Commander Keen: Aliens Ate My Babysitter!

Development

Even though this is the last game in the series, this was not the last one to be created. Commander Keen 5: The Armageddon Machine was created after Commander Keen 6: Aliens Ate My Baby Sitter! because the latter had to go to retail and that required lead time.

Distribution

In contrast to the former entries in the series, this game is commercial instead of shareware. FormGen convinced id to put copy protection in the game.

Planned trilogy

This game was planned to be the start of another trilogy and the ending leaves a remarkably large gap for a sequel(s). It even makes a promise for 'the biggest adventure yet' in Christmas '92. The crew then tripped on the distraction that changed the path of PC gaming, Wolfenstein 3D.
