Metal Gear Japanese: Hepburn: Metaru Gia is a series of action-adventure stealth video games created by Hideo Kojima and developed and published by Konami. The first game, Metal Gear, was released in 1987 for MSX home computers. The player often takes control of a special forces operative (usually Solid Snake or Big Boss), who is assigned the task of finding the titular superweapon “Metal Gear”, a bipedal walking tank with the ability to launch nuclear weapons.
Several sequels have been released for multiple consoles, which have expanded the original game’s plot, adding characters opposing and supporting Snake, while there have also been a few prequels exploring the origins of Metal Gear and recurring characters. The third game in the series, Metal Gear Solid for the PlayStation, marked the beginning of a whole new line of 3D for Metal Gear. As of September 2019, over 55 million copies of games in the franchise have been sold worldwide, with individual installments critically and commercially acclaimed and receiving several awards.
The series is credited for pioneering and popularizing stealth video games and “cinematic video games”. Notable traits of the series include stealth mechanics, cinematic cutscenes, intricate storylines, offbeat and fourth wall humour, and exploration of cyberpunk, dystopian, political and philosophical themes, with references to Hollywood films to add flavor. The franchise has also been adapted into other media, such as comics, novels, and drama CDs. Solid Snake also appears in Super Smash Bros. Brawl and Super Smash Bros. Ultimate.
