Against all odds, a nuclear crisis and the inevitable retaliations are avoided. Finally, Big Boss has to neutralise his own Metal Gear which has been stolen by Paz, a secret agent sent by Zero, alias Cipher, to convince Big Boss to join him back. Paz is ejected into the ocean and Big Boss has to carry on with “Militaires Sans Frontières”, known in the future as “Outer Heaven”, with the entire world's eyes on them.
