MG2 Production

After the release of the NES version of Metal Gear in North America, Konami commissioned the development of a sequel for the NES, Snake's Revenge (a game made specifically with the American market in mind), without the consent of Metal Gear creator Hideo Kojima.

According to Kojima's account of the events, he did not have any plans to design a Metal Gear sequel at the time and was unaware that a sequel was being produced until he became acquainted with a member of the Snake's Revenge development team on a train ride in Tokyo. Kojima was then informed about the development of Snake's Revenge and was told "it's not the authentic Snake, so please create a new Snake game of your own." After being given the go-ahead by his bosses at Konami, he began developing Metal Gear 2: Solid Snake with the MSX division of Konami. Metal Gear 2 serves as a follow-up to the original Metal Gear, ignoring the events of Snake's Revenge (which was unreleased in Japan), and every canonical Metal Gear title released afterward acknowledge only the events of Metal Gear 2, relegating Snake's Revenge to an apocryphal status.
