Although 8-bit styled, Perfect Harmony appears to combine classic and X gameplay, giving Mega Man and Proto Man as they appear in the above trailer more moves, as well as swords, because why not? If they seem overpowered, you should take heed to the enormous waves of enemies they're facing at times. If you like what you can see, you can keep track of Perfect Harmony on Rocks Clan.
C'mon Capcom, you had fun coop working all the way back with Rescue Rangers. Give us our Mega Man coop excitement!
