Players control Mega Man in side-scrolling stages filled with jumps, hazards, and enemy fire. Defeating Robot Masters grants their special weapons, and choosing the right weapon for the right boss can greatly reduce difficulty. The new charge shot adds a stronger primary attack that can be released at any time. Progress is stage-based, with password continuation supporting longer play sessions and repeated boss attempts.

The game uses passwords to resume progress and continue from later stages.
