Mega Man IV — About this game
Mega Man confronts another set of Robot Masters after Wily disrupts a robot exhibition. Collect P Chips to exchange for helpful supplies, and use a charged Mega Buster alongside the weapons earned from bosses. Beating a Robot Master adds a special weapon to the equipment menu. Try different weapons against bosses and watch their remaining energy rather than relying on the same attack everywhere. Health and weapon refills help sustain a route through hazards and repeated boss attempts. Press START and choose a boss portrait with the D-pad, then confirm with A. Practise the basic weapon before committing to a jump; use the equipment menu to try newly acquired weapons.
