Rockman 2 Plus! is a ROM hack of Mega Man 2 that changes the levels and the graphics. The settings for the lands of each Robot Master appear have themes that deviate from the usual robot science fiction setting of Mega Man, with a level that's full of clocks and a level that appears to be straight out of Castlevania. Even the Robot Masters have wildly different graphics, with one called "Liquidman" being a mass of water.
longbao for this run zips through the game as fast as possible, utilizing the usual Mega Man 2 glitches and techniques in the process.
