200 km north of Galzburg, South Africa, lay the fortress of Outer Heaven, a fortified state that had been founded by a legendary mercenary in the late 1980s. In 1995, the Western world had received intelligence that warned of a weapon of mass destruction that was supposedly being constructed deep within the fortress. High-Tech Special Forces Unit FOXHOUND, commanded by the legendary soldier Big Boss, sent their best agent, Gray Fox to infiltrate the stronghold. However, days later, contact with Gray Fox was lost, his final transmission consisting only of two words: "METAL GEAR...".
With the goal of rescuing Gray Fox and uncovering the meaning of the cryptic message, rookie operative Solid Snake is sent into Outer Heaven alone.
