Official progress updates, answers to questions, and the like are posted by JKB Games on their Facebook page. The game currently has no set release date. Along the way they must fight the usual eight Maverick bosses, and they also gain new Maverick Hunter allies such as Synthia. The game's story takes place in an Alternative Continuity after Mega Man X5, where X and Zero are forced to fight a dangerous new Maverick called Strike who hijacks X's Ultimate Armor and threatens to bring the world into ruin again. However, the game also differs from the original series by being a Metroidvania-styled game (similar to Mega Man ZX) where X and Zero can level up and earn skill points to power up their attacks and weapons. The game uses the retro 16-bit graphics and SNES-like music of the Mega Man X series. The project has been in development since the late 2000s, and production is still going strong.

It was formerly being made in Flash Develop, but later moved to HTML5. Mega Man X: Corrupted is an upcoming Mega Man X fan-game being developed by John K.
