Mega Man X: Corrupted is an unofficial, fan-made game in development by John K. Bacchus (also known as JKB) coded in AS3 using Flex compiler on Flash Develop, but as Flash was phased out at the end of 2020, it was switched to HTML5. The game is modeled after the MMX series' features and gameplay, in the graphic style of the SNES Mega Man X games, with a non-linear interconnected environment, and skill trees to enhance characters and weapons.

This title is currently still in development, but will be free on launch.

Very little has been revealed about the story, though JKB has confirmed that the game will take place as an alternate time line after Megaman X 5, thus Axl and other characters introduced in Megaman X 6 and on will not make an appearance. But it seems this now null with the renal that Rainy Turtloid, a boss introduced in Megaman X 6, is appearing in the game. Here's what we know so far:

In X's intro stage, X fights a Maverick named Strike, who steals his Ultimate Armor.

In Zero's intro stage, Zero wakes up in a capsule with his Z-Saber outside of it.
