Operation Ocflore is a Keen 4 mod by Bubbatom. The mod's development was first announced on Keen Day 2014. A one level demo version was released on Keen Day 2015. This mod is notable and unique for using a differing color palette.
The titular setting of the mod is the planet Ocflore V, which is almost completely covered in sea. The complex storyline involves an alien race known as the Ormch who are behind "The Ocflore Project". The Ormch make profit of a precious substance known as Ostrum, which can only materialize when intelligent life forms are paired with so-called Ostrum Zones.
One of those Ostrum Zones was found by them on Ocflore in the distant past. Since then, the Ormch have placed other alien races on Ocflore to gain Ostrum, most recently the Enkri. Each previous race was eradicated once the Ormch didn't need it anymore. Now, the Ormch intend to shut down the current stage of The Ocflore Project, and ask Commander Keen for assistance.
The player has to decide whether he or she wants to help the Ormch or to save the current life forms of Ocflore from annihilation. In case of the former, the action takes place on a destructive spacecraft rather than the planet. Therefore, the final mod is intended to have two different plot lines with their own levels each and different endings.
In terms of level structure, the original Keen 4 acts as the model, the best episode in the author's opinion.
