The Moons of Morkador
The Moons of Morkador is an abandoned Keen 2 mod released by The Shifted One.
Development of the mod started in 2009, but it was abandoned the same year. In January 2013, the author released the unfinished work in its 2009 state, save for a bugfix. It features new graphics, patched enemies and a new alphabet, among other things. Two of the three levels can be completed, while the third one is only halfway done. The Shifted One stated that he may continue working on the mod someday.
The mod's story, which is not included, involves space pirates who try to create a doomsday weapon by using the special powers of certain crystals they mine, and Keen has to stop their activities.
Spoiler Warning! This shows the whole levels.
