Mega Man 4 Original Soundtrack OST
Platforms: Game Boy
Doctor Wiley has once again returned to hassle Mega Man with 8 new robot masters, and a brand-new 'Mega Man Killer' robot, named Ballade. Players make their way through themed levels to defeat the Robot Masters, eventually taking their abilities once they do so, using them against Wiley and his minions. The game was released in December of 1993 and did well enough that multiple Mega Man sequels have been made.
