It's MEGA MAN versus the powerful leaders and fighting forces of Monsteropolis — that strange multi-layered land of robot-like Humanoids created by the wrongly-performed experiments with human beings by Dr. Wily.

MEGA MAN — chose defender of the human race. Fr he dares to single-handedly penetrate Monsteropolis' seven separate societies to stop the rapid expansion of strange misrepresentations of humans.

MEGA MAN's goal is monumental. He must infiltrate seen separate heavily-guarded empires. By himself, he must break-down and destroy the followers of empire leaders: Cutman, Gutsman, Iceman, Bombman, Fireman, Elecman and Dr. Wily.

The action involves MEGA MAN armed only with laser beam weapons, encountering strangely-configured Humanoids. They're atop, in and out of fortified prison-like structures strengthened with thick walls. Below icefields. Hidden amid gun turrets imbedded in concrete uprights, even in subterranean passages under icefields. WOW!
