Metal Gear Solid

Metal Gear (Japanese: メタルギア 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 the MSX2 home computer architecture. The player takes control of a special forces operative (usually Solid Snake or his father, Big Boss) who is assigned to find the titular superweapon "Metal Gear", a bipedal walking tank with the ability to launch nuclear weapons. Several sequels have been released for multiple consoles after requests from Konami to produce new Metal Gear games. The sequels expand the original game's plot adding new characters opposing and supporting Snake, while there have also been a few prequels exploring the origins of the Metal Gear and recurring characters. Various parts were inspired by Hollywood films with character's names, settings and artworks often referencing them.
