In this game, Dr. Wily introduces his own eight Robot Masters. Taking place some time soon after Rockman 1, the sequel begins with a view of Tokyo and its mountainous backdrop at night. In the foreground, we see a large building. As the prologue unfolds, the angle pans up the building until we see Rockman standing on top, helmetless.
So begins the second Rockman game.
This game is also known as Megaman 2 in Europe.
