JKB Games has just released an update not only about the progress of the project, but gave us an insight on some innovating measures taken to produce levels inside of Mega Man X: Corrupted a bit quicker.
For all of the curious developers reading, the game is also being migrated to AS3, also known as ActionScript 3. This technology will allow you to enjoy playing the game with not only better performance, but also in full screen mode!
Take a look at the screenshot below to get a glimpse of the level editor. Unfortunately, downloads to JKB Games’ level editor will not be available for others as it’s programmed specifically for Mega Man X: Corrupted.

The game editor is Mega Man X: Corrupted specific and will not work with any other Mega Man fanmade projects.
