Commander Keen in Mineepleo is a Keen 1 mod by Bonevelous (previously known as Harvey). It involves Keen being invited to an intergalactic party by the Vorticons. However, Mortimer creates a decoy Vorticon VI looking exactly like the real one. When Keen tries to land on the planet with the Bean-with-Bacon Megarocket, a magnetism on it forces him to crash land, and then the planet instantly transforms into its true form – Mineepleo. On Mineepleo, Keen has to find the four energy sources of the magnetism to escape. The mod is notable for its heavily modified color palette.
On Keen Day 2009, the first demo version with one level was released. Two more demos were also released in March. The second one introduces a new world map and another level, while the latest version features five levels in total. No new versions of the mod have been released ever since.
