Regulator (Fallout 3)

The Regulators are a group of self-appointed lawmen who wear cowboy style hats and Regulator Dusters after the fashion of gunslingers. In the Capital Wasteland they are led by Sonora Cruz and operate out of a farmhouse.

If the player has the Lawbringer perk, he/she can trade fingers taken from the corpses of evil humans killed by the player, for good karma and Bottlecaps. The Regulators will also attempt to claim the bounty on the player's head if he or she commits serious crimes, such as destroying Megaton or enslaving people in the Capital Wasteland.

Members
Regulators wear Regulator Dusters, and use laser weapons (Laser Pistols and Laser Rifles) although more commonly they are equipped with Combat Shotguns, Chinese Assault Rifles and Combat Knives. In terms of durability and combat challenge, they are about equal to a Talon Company Merc (although with severely less protective armor). Regulator patrols typically operate in 3-man squads when searching the Wasteland for the player character if that player is evil or very evil. They are no more deadly or effective than their evil counter parts Talon Company Mercs and it would be wise to take out the one with the longest range weapon first and then backpedal (whilst firing) to some cover and take potshots at the one with the Combat Knife or Combat Shotgun.

If you have the Lawbringer perk, a Dead Regulator will be found outside of the entrance to Arlington/Wasteland Metro in Arlington Cemetery North. He will have a bounty note for Junders Plunkett. It says he was last seen in Canterbury Commons, but really he is in the nearby Arlington House. You can kill him and take his finger. It is worth 1,000 caps back at the Regulator HQ.

Lucas Simms, the sheriff of Megaton, is also a Regulator But is not IN the Regulator faction (Retired?).

Bugs

 * There is a bug where a player can pick-pocket a regulator, and he/she will have a named bounty for the player on them, even if the player is completely good. (confirmed XBOX 360,PC, and PS3)
 * Sometimes the Regulators will go through their dialogue as if they are hostile, but upon completion, they do not fire and appear friendly. They do not move or in any way pursue the player. Once fired upon, or more preferentially a well placed grenade, they do become hostile and return fire. They have the player's bounty on their bodies. (confirmed Xbox 360)
 * If the player has access to the Regulator HQ and murders all of its Regulator inhabitants, Sonora Cruz will still remain friendly towards you and act as if nothing has happened. (confirmed on PS3 and Xbox 360) On the PC version, you can still murder all the inhabitants as long as nobody else sees you doing it, without anyone becoming hostile. Interestingly, you can do so without any karma loss.
 * Sometimes giant rad scorpions will spawn nearby and scare off Sonora Cruz. (confirmed on PS3 and Xbox 360)
 * FIX: For the above bug: When she is running away, attack her until you get the dialog box saying that she is unconcious. Kill the Giant Radscorpion and then run up to Sonora Cruz and talk to her. She sould give her normal dialog.
 * If you murder the regulators (IE via the sandman), then attack Sonora Cruze, she may runaway never to return, or despawn, thus making the on going quest and the perk void.
 * FIX: For the above bug: Go to Wheaton Armory, look around your map for a green friendly mark, or by any other means, locate her. Punch her and herd her back toward the Regulator HQ, wait a few days/or finish her off inside, as to reset her AI.

Trivia

 * The Regulators may be a reference to the Regulator-Moderator War that took place in East Texas during the 19th century because no proper law enforcement was present at the time. This would also explain the cattle, cowboy hats, and dusters.
 * Regulators and Raiders may be a reference to the two groups in Andersonville, a Confederate prison used to house Union troops during the Civil War. The Raiders were a group of basically bandits and thieves that would assault and murder fellow captives in order to boost their own prison existence. The Regulators is a group of Union captives that joined together and brought the Raiders to justice.
 * Regulators could also be a reference to those under the command Daniel Shays that rose up on behalf of poor farmers in New England, shortly after the American Revolution.
 * Regulators are, however, the actual term for an official who maintains control and supervision of an area of public interest.

Appearances in games
Sonora's Regulators appear only in Fallout 3. It must be noted that these Regulators are NOT affiliated in any way with Caleb's Regulators in Fallout 1. They share absolutely nothing in common other than, out of pure coincidence (and some irony), the same name.
