"The world is covered in noise"
Geo Stelar, aka Mega Man, has concurred several trials over his life. Once closed to the world, he has learned to open up, and has made many new friends. Having saved the world twice already, the Blue Bomber has made himself quite popular, and fans are popping up by the day!
But now, mysteriously "noise waves" are popping up, and it's up to Mega Man, as well his friends and his partner Harp Note to investigate!
This game is also known as Ryuusei no Rockman 3: Red Joker in Japan.
