A longplay of Mega Man 3.
Mega Man 3, known as Rockman 3 Dr. Wily no Saigo! ("Rockman 3: The End of Dr. Wily!") in Japan, is a video game developed and published by Capcom for the Nintendo Entertainment System. It is the third game of the original Mega Man series and was originally released in Japan on September 28, 1990. The game localized in North America later in 1990 and in European regions in 1992. Taking place after the events of Mega Man 2, the plot follows the titular hero as he helps his creator, Dr. Light, and a former villain, Dr. Wily, collect parts for a peacekeeping robot by defeating several Robot Masters that have gone haywire.
Mega Man 3 takes place during an unspecified year during the 21st century (200X). The mad scientist Dr. Wily, having twice had plans for world domination dashed, claims to have reformed and begins work with Dr. Light on a project to build a peacekeeping robot named "Gamma". Robot Masters in charge of a set of "mining worlds", however, go berserk and make off with Gamma's eight power crystals. Mega Man is called into action, this time with a canine companion named Rush, to retrieve the crystals from the sites. Throughout his mission, the protagonist continuously encounters and spars with Break Man, a masked foe who has abilities comparable to Mega Man's own. After Mega Man destroys the eight Robot Masters, he must then revisit four of the mining sites to face off against eight "Doc Robots", who possess the abilities of the Robot Masters from Mega Man's most recent mission. Once the crystals are retrieved, Wily reverts to his evil ways, steals Gamma, and retreats to his new fortress. To stop Wily's newest plan to conquer the world, Mega Man destroys Gamma and defeats Wily in a final confrontation. As the fortress begins to crumble, Break Man appears in enough time to save Mega Man, but is too late to save Wily, who is seen being crushed under the rubble. When Mega Man regains consciousness in Dr. Light's lab, his creator informs him that he must have been rescued by Proto Man, Mega Man's brother.
