The BGM for the third level of the Wily Tower in the same-titled mode of Rockman Mega World.
The ascent finally leads Rock into the night sky as he does battle with enemies and dodges traps... Leading into a rematch with Buster Rod G, who has ditched his rod for a simple arm cannon.
In essence, G is little more than an obstacle providing a hitbox for the level's true boss - a series of collapsing platforms falling through a long shaft. Rock has to keep jumping upwards while dodging G's shots and delivering enough of his own finally defeat the mad monkey machine once and for all.
