Mega Man, known as Rockman[a] in Japan, is a 1987 action-platform video game developed and published by Capcom for the Nintendo Entertainment System (NES). It was directed by Akira Kitamura, with Nobuyuki Matsushima as lead programmer, and is the first game of the Mega Man franchise and the original video game series. Mega Man was produced by a small team specifically for the home console market, a first for Capcom, who previously focused on arcade titles.
The game begins the struggle of the humanoid robot and player-character Mega Man against the mad scientist Dr. Wily and the six "Robot Masters" under his control. Mega Man's nonlinear gameplay lets the player choose the order in which to complete its initial six stages. Each culminates in a boss battle against one of the Robot Masters that awards the player-character a unique weapon. Part of the strategy of the game is that the player must carefully choose the order in which to tackle the stages so that they can earn the weapons that will be most useful for future stages.
Critics praised Mega Man for its overall design, though the game was not a commercial success. Mega Man established many of the gameplay, story, and graphical conventions that would define the ensuing sequels, subseries, and spin-offs in the Mega Man franchise. The game has since been featured in game compilations, including Mega Man Legacy Collection for Windows, PlayStation 4, Xbox One, Nintendo 3DS, and Nintendo Switch, rereleased on mobile phones, and become a part of console emulation services. It received a full 3D remake titled Mega Man Powered Up in 2006.
