The 3-D Mega Man Doom mod has been mentioned before on other websites, but there is finally an official trailer from its creator, CutmanMike. Mega Man 8-Bit Deathmatch takes your favorite Mega Man characters and deposits them and their weapons into a 3-d map. The result looks incredibly fun! From CutmanMike:

Megaman 8-bit Deathmatch will play as if Megaman suddenly turned 3D. Everything will play as if it was being played back in 1987. Levels will use purely 8-bit textures and sprites. Megaman will jump high and take damage recoil. Weapons will behave almost exactly as they did back then, only from a 3d perspective. The plan is to eventually have all the levels and weapons from Megaman 1-6 (and maybe 9). Obviously some weapons will have minor changes because there are a lot of clones throughout the series.

This awesome trailer...well, I'll let you check it out for yourself.

Thanks to Daniel for the tip!
