Snake's Revenge is a licensed but non-canon sequel to the original Metal Gear for the NES. Three years has passed since the Outer Heaven incident. FOX-HOUND has gained intelligence that an unknown terrorist group has seized a remote facility containing mass-produced Metal Gear tanks, as well as a new Metal Gear prototype which was under development. The newly-promoted Lt. Solid Snake is called back into action to infiltrate the terrorists' base with the help of two FOX-HOUND rookies, former marine Nick Myer and navy intelligence agent John Turner.
