So, I finally got a chance to try out CutmanMike's MegaMan 8-bit Deathmatch...
It's wicked sweet.
Why are you still reading this? You should be playing this game NOW.
Get it here.
Side-note: Chiptuned RockMan is awesome. They managed to make SlashMan's theme sound cool, which is quite a feat by itself, and the "Buster Core" remix of Kaze yo Tsutaete is ridiculously amazing. I just wish they used the Saturn version of TenguMan's theme. It's so much cooler.
