Metal Gear is a hugely successful and critically acclaimed series of stealth games created by Hideo Kojima and developed and published by Konami. In the series, the player takes control of a Special Forces Operative (Solid Snake in most games) repeatedly facing off against the latest incarnation of the eponymous superweapon, "Metal Gear", which is usually a bipedal walking tank with nuclear launching capabilities. The series is famous for its lengthy cinematic scenes and intricate storylines as well as its exploration of the nature of politics, warfare, censorship, genetic engineering, artificial intelligence, loyalty, reality, subjective vs. universal "truths" and various other philosophical themes. The acronym for the series, MGS (Metal Gear Solid) is also an acronym for these central themes, which are "Meme", "Gene", and "Scene".
