The game uses a side-view arena perspective. A player selects Rockman, Blues, Forte, or Duo, chooses a route, and fights a sequence of Robot Masters before confronting Dr. Wily's forces. Battles are organized as compact boss arenas rather than scrolling platform stages.

Players run, jump, fire, and use acquired special weapons. Defeated bosses provide weapons that can exploit later weaknesses, while energy and score management support continued arcade play. One- or two-player modes are available, with cooperative combat in two-player games.

Learn each Robot Master's attack rhythm before committing to close range. Jump over predictable projectiles, keep moving, and punish recovery animations rather than trading hits.

Use newly acquired weapons on bosses with matching weaknesses when possible. In two-player mode, separate targets and revive pressure by alternating attacks instead of standing in the same space.
