We're the Regulators. We've dedicated our lives to bringing the evil to justice. And out in the Wasteland, there's only one brand of justice: the gun.Sonora Cruz

The Regulators are a group of vigilantes who wear cowboy-style hats and Regulator dusters in the fashion of pre-War gunslingers and outlaws.


The Regulators are a relatively new group in the Capital Wasteland, having appeared only in 2267 or so. They take it upon themselves to hunt down troublemakers and do their best to keep a semblance of peace wherever they are.[1]

In the Capital Wasteland, they are led by Sonora Cruz and operate out of the Regulator HQ. Unlike the corrupt Regulators seen in the original Fallout, the (non-related) Regulators of the Capital Wasteland are truly just-minded and seek to punish evil.

With the Lawbringer perk, fingers can be taken from the corpses of evil humans and ghouls and can be traded for good Karma and 5 to 10 bottle caps depending on Karma level. On the other hand, the Regulators will also attempt to claim the bounty on the Lone Wanderer's head if they have accumulated bad Karma by committing serious crimes, such as destroying Megaton or enslaving people in the Capital Wasteland, or by simply murdering people.

Littlehorn & Associates are the Regulators' antagonist faction, and are associated with the Contract Killer perk.

Behind the scenes

  • The Regulators of Fallout 3 are a separate entity from that of the Boneyard Regulators met in the first Fallout.[1]
  • Regulator is the actual term for an official who maintains control and supervision of an area of public interest.[3] As a result, many armed groups, both vigilante and official, have been named "Regulators" throughout American history. One of the most notable groups in American history were the Regulators of the Carolinas around the time of the American Revolution.

  2. Fallout 3 Official Game Guide Collector's Edition, p. 360: "Luca Simms
    He grew up in Megaton and understand better than anyone what it takes to survive and thrive in the Wasteland. Big and imposing yet warm and friendly, Lucas won his position by an unanimous vote of the people of Megaton (most of whom genuinely love the guy). He serves as a mayor, sheriff, judge, and just about any other position that's needed. It is also no secret around Megaton that Lucas Simms is fulfilling some weird childhood cowboy fantasy. He named his son Harden after the Old West outlaw John Wesley Harden. Simms is also a member of a secret society known only as 'the Regulators'."
