Somewhere in that great checklist of "things Capcom haven't done with Mega Man yet" is a fighting game. It may never happen. Right now, though, there's a trailer out for a fan-game called Mega Man Arena. The project aims to pick up the slack and look good while doing it.
Mega Man Arena is a four-player fighting game in the vein of Super Smash Bros. developed by Jeff "KishSquared" Kish. It will feature nine characters from Mega Man 1 and Mega Man 2, twenty seven stages, team battles and... chickens. It's due out in early 2018 and looks super rad.
You can catch an early look at the game live on November 4th for charity. Hit up the video's description for more details!
