Mega Man returns to Game Boy in this remixed version of past NES titles. New features from previous handheld games include the ability to power-up shots by holding down a button, an option to purchase items at the end of each stage, and the addition of a new ally named Beat. The game otherwise follows an identical format to previous Mega Man titles, which involves choosing a stage and battling a series of robot masters for their powerful weapons. Featured bosses include Toad Man, Bright Man, Pharaoh Man, Ring Man, Charge Man, Napalm Man, Stone Man, and Crystal Man. Defeat all eight for a chance to confront evil mastermind Dr. Wily.
