If you and everyone in your regional server disarms all nuclear weapons, a secret event will be triggered in Metal Gear Solid 5: The Phantom Pain.

Nuclear disarmament is a major theme of the Metal Gear series. Triggering the secret event comes with a few other requirements. Konami writes:

  • You must have completed Mission 31.
  • You must not own or be currently developing a nuclear weapon. If you have any nukes in stock, you must dismantle them.
  • Certain conditions related to nuclear proliferation must be met on the regional server for your corresponding gaming platform
  • All nuclear weapons on the regional server corresponding to your console or platform must have been dismantled. In other words, the amount of nukes on your platform’s server must be equal to 0.

As of November 25, the Xbox 360 had the lowest number of nuclear weapons, with 85. PC players on Steam were lagging behind, with 15,691 weapons left to dismantle.

When the event is triggered, players can access it by returning to Mother Base, or after completing a main mission of the game. Konami also says the event can be repeated by re-fulfilling all the conditions, should players start arming their nukes again after all four requirements are met.

Metal Gear Solid 5: The Phantom Pain is available for PS4, PS3, Xbox One, Xbox 360, and PC.
