This is the forum to discuss existing patches, request new ones, speculate on possibilities, complain about progress of your mod, or otherwise talk about the Keen:Galaxy duet, and the standalone Keen:Aliens.
Keep in mind that while Keen4 is shareware, Keen5 is not, and Keen6 has been discontinued, making it difficult to obtain. Distribution of Keen5 and Keen6 isn't legal, and piracy is frowned upon.
