The game uses a side-scrolling perspective with classic run-and-jump action. Players select one of eight Robot Master stages and, after defeating the boss, gain that boss's weapon. Mega Man can fire the Mega Buster, slide under low obstacles, and use Rush's support forms to traverse terrain and reach platforms. Stages mix platforming, hazards, enemy waves, checkpoints, and boss fights, with later sections expanding into multi-boss progression. Resource management matters because special weapons consume energy.

Mega Man

The blue robot hero and main playable character.

Proto Man

A mysterious robot connected to the series' larger story.

Rush

Mega Man's robotic dog companion, providing mobility support.

Dr. Wily

The recurring villain behind the game's main conflict.

Choose a stage order that exploits boss weaknesses to reduce early pressure. Use the slide proactively to avoid projectiles and move through tight spaces faster. Save powerful weapon energy for bosses or difficult platform sections instead of spending it freely. Learn boss attack patterns and take advantage of invincibility frames after taking damage.
