Mega Man 8-Bit Deathmatch, the fan-made Doom mod, at least released on Friday. The FPS, stuffed full of Mega Man characters, weapons and other assorted sprites, is free.
CutmanMike and his team of rippers, spriters and modders spent more than a year building the game. You can see all of their names in that credit sequence above.
