301 - Snake's Revenge

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.
