The year is 1995. Near South Africa, a military base called Outer Heaven has emerged and is said to house a weapon of mass destruction known as Metal Gear.
A U.S. special forces group called FOX-HOUND was sent to infiltrate the base, but they lost contact with their lead operative Grey Fox.
So, you (code named Solid Snake), a rookie to the group, are sent in to rescue Grey Fox and destroy Metal Gear, a walking tank capable of launching nuclear weapons.
And so begins the game that spawned 4 direct sequels (with a 5th on the way) and several spin-offs.
Released in 1987, Metal Gear differed from most other video games at the time. Rather than running around and shooting anything that moved, the focus was on avoiding all confrontation with the enemy.
