Nico Thulin creates a web series online where he completes the classic Mega Man series on the Nintendo Entertainment System with mind-breaking rules: He must wield Mega Man's default weapon, mega buster only, not get hit once and not miss a shot. Three other individuals find him online and follow in his footsteps performing the same challenge. They quickly feel like a family and create their own community called Snupster, where they perform insane runs on retro games. They decide to turn against each other and race the classic Mega Man series and see who the true king of the bunch is. There is no end in sight.
