The 22-year-old built the mod (still in alpha) as an homage to "the time when I feel Mega Man was in full fruition: on the NES," harnessing not just 8-bit sprites for characters but for entire levels. Mike Hill's hope is that someday the mod will contain "all the levels and weapons from Mega Man 1–6 (and maybe even 9)," though, as of right now, he's still got a long way to go. "Right now the gameplay is a bit slow paced and unbalanced, and the maps are extremely difficult to navigate ... expect a more stable release some time next year." He promises more levels and more weapons in 2010, but we're hoping the power of Joystiq BioMass™ can spur Mike on to get us more Mega Man deathmatch asap. Go forth and comment, BioMass!
Update: We've added a video of the mod in action just after the break.
