It's MEGA MAN versus the powerful leaders and fighting forces of Monsteropolis - that strange multi-faceted land of robot-like Humanoids.

Brilliant scientist Dr. Wright conceived the construction of fully-operational human-like experimental robots to perform specific everyday duties. Dr. Wright, and his assistant Dr. Wily, encouraged with their very first near-human robot - MEGA MAN - proceeded to develop six additional Humanoids, all programmed to perform prescribed rituals.

But, with the exception of MEGA MAN, all of Dr. Wright's near-human robot experimentation went awry. Assistant Dr. Wily turned disloyal, re-programming Dr. Wright's Humanoids, now bent on destroying opposition so Dr. Wily could control the world and its resources.

Resisting re-programming, MEGA MAN is chosen the defender of the universe and its inhabitants. MEGA MAN dares to single-handedly penetrate seven separate empires of Monsteropolis, eliminating the leaders and followers of these sovereignties.

Get ready for some very exciting challenges!
