This page lists the known versions of Keen 5 and any differences discovered between the versions.

Keen 5, despite not having that many revisions still has quite some interesting history. Firstly, it is one of the two Keen games (the other one being Keen 3) that had a relatively critical bug in the initial release. Entering the Korath III Base secret level when playing with easy as the level of difficulty in the initial release of the game lead to a crash. Secondly, Keen 5 is also the only game in the series where something got censored in a later revision. The swastika that appeared in the Energy Flow Systems level ended up changed.
