By its fourth handheld outing, Capcom's Game Boy Mega Man series had found its footing, and many fans consider this 1993 Minakuchi Engineering game the best of the five. The structure follows the series formula: four Robot Masters from Mega Man 4, including Toad Man and Pharaoh Man, followed by four from Mega Man 5, among them Crystal Man and Napalm Man. This time the Game Boy-exclusive Mega Man Killer is Ballade, who returns with a twist later in the game.
Mega Man IV brings in two features the earlier handheld games lacked. The charged Mega Buster finally arrives, and P-chips collected in stages can be spent in Dr. Light's lab on Energy Tanks, extra lives, and other useful items. That shop takes much of the edge off the series' famous difficulty and makes progress feel steady. The stages are also larger and more detailed than in previous Game Boy entries, and the sprites look closer than ever to the NES originals.
Tips for Mega Man IV
Spend P-chips on Energy Tanks before the final stages; the item shop is your best defense against the late difficulty spike.
Charged buster shots break through enemy guards that block normal shots, so hold fire while approaching.
