Ultimatum is a unique weapon in the Fallout 4 Creation Club content "Tunnel Snakes Rule!"

Characteristics[]

This section is transcluded from 10mm pistol. To change it, please edit the transcluded page.

The Colt 6520 10mm autoloading pistol is a highly durable and efficient weapon developed by Colt Firearms prior to the Great War.[1] It proved to be resistant to the extreme conditions of the wasteland and is a fine example of workmanship and quality construction. Its simple design allows it to be easily manufactured with relatively basic equipment, making reproduction possible in workshops across the post-nuclear world. The Colt 6520's reliability and accessibility makes it very popular among wasteland denizens, for who sophisticated, high-maintenance weapons would be a liability to survival.[2]

Unlike the standard classic 10mm pistol, Ultimatum possesses a black finish and intricate engravings. On the right side of the gun are engravings of dice, four-leaf clovers, flames, and a Vault Boy face with the following inscription on the barrel:

A bullet is worth a thousand threats
and I have twelve

On the left side of the gun are engravings of trees and crows, a bottlecap, and flames with the following inscription on the barrel:

Be not afraid of any beast, no matter what the size
When danger threatens, wield me, and I shall see to its demise

On the top of the gun are engravings of the Sole Survivor, a deathclaw arm and multiple Gunners logos. Lastly, on the back of the barrel behind the sights is an engraving of a radiation hazard symbol. Right above the muzzle is an engraving of the words "LOOK HERE."

Due to the unique model used for these engravings, Ultimatum cannot be equipped with barrel modifications. By default, it carries the glow sights, survivor's grip, and muzzle brake modifications. It possesses the "Irradiated" Legendary effect, adding 50 radiation damage to every shot.

Found on Wally Mack, in the subway maintenance access section of the Fens Way station.

  1. In-game description in Fallout and Fallout 2: "{801}{}{A Colt 6520 10mm autoloading pistol. Each pull of the trigger will automatically reload the firearm until the magazine is empty. Single shot only, using the powerful 10mm round. Min ST: 3.}"
  2. Vault Dweller's Survival Guide p.5-15: "This is your basic ranged weapon. The 10mm round packs a goodly punch, and the Colt pistol is a fine example of workmanship and quality. It is a single shot weapon only, meaning that every time you pull the trigger, you will fire one, and only one, round of ammunition. The 6520 has no problem feeding hollowpoint ammunition for small game hunting, or armor piercing rounds for larger, bipedal game."
