Metal Gear 2: Solid Snake (メタルギア２ ソリッドスネーク, Metaru Gia Tsū Soriddo Sunēku?, commonly abbreviated MG2) is an overhead stealth action game (officially promoted as a "Tactical Espionage Game"[1]) that was originally released by Konami in 1990 for the MSX2 computer standard exclusively in Japan. Metal Gear 2 was directed and written by Hideo Kojima, who also designed the MSX2 version of the original Metal Gear. While a previously developed Metal Gear sequel titled Snake's Revenge (a non-canonical installment produced without Kojima's involvement) was released for the Nintendo Entertainment System in North America during the same year, Metal Gear 2 itself did not have an official English version until its inclusion as a bonus game (along with the first Metal Gear) in Metal Gear Solid 3: Subsistence for PlayStation 2 in 2006, almost 16 years after its original Japanese release.
