Video Game: Mega Man X Corrupted

Back to 16-bit, no less!
Mega Man X: Corrupted is an upcoming Flash fan-game by JKB Games. The game uses the retro 16-bit graphics and SNES-like music of the Mega Man X series. However, the game also differs from the original series by being a Metroidvania-styled game where X and Zero can level-up and earn skill points to power up their attacks and weapons.

Official progress updates, answers to questions, and the like are posted by JKB Games on their Facebook page, and although the game itself is still unreleased, it has a fansite here.
