The year is 1995. Deep in South Africa, 200km north of Garzburg, Outer Heaven-
an armed fortress nation, established by the legendary mercenary. He was
feared in combat by both his friends and foes as a hero and a lunatic. The
"Western" nations have found that a weapon of mas destruction capable of
rewritting war history is under development at Outer Heaven. They have called
upon the high-tech special forces unit FOX-HOUND to take care of the
situation. In response to this order, Big Boss, the commander-in-chief of
FOX-HOUND, sent Gray Fox, the man with the code name "Fox" which is given to
the best member of the unit "Operation intrude N313"

After a few days, his last message being "Metal Gear..." Gray Fox was missing
in action. Taking the situation seriously, the top men of the "West" again
called for FOX-HOUND. Big Boss selected Solid Snake, who had recently joined
FOX-HOUND, aYEAH, I'M BIG BOSS
