What is your major malfunction, maggot?

Deputy Steel is a Mister Gutsy that guards Megaton's armory in 2277.


Previously purchased from Tinker Joe,[Non-canon 1] Deputy Steel is a General Atomics Mister Gutsy, reprogrammed to assist Sheriff Simms with upholding security in the armory. It got its deputy title from Simms, who is living out his Wild West childhood fantasies.[Non-canon 2] Every once in a while, Deputy Steel gets some polishing from Harden Simms.[1]

Interactions with the player character

Interactions overview

38 Paradigm of Humanity.png
This character has no special interactions.

Other interactions

  • If the Lone Wanderer has a Science skill of 75 or more, they can deactivate both Deputy Steel and Deputy Weld using the computer terminal in the armory. If a Stealth Boy is used before entering, the Lone Wanderer might sneak over to the terminal undetected to deactivate Deputy Steel and loot the place without any conflict.

Effects of player's actions

  • If Deputy Weld, Megaton's Protectron guard, is destroyed after Broken Steel is installed, Deputy Steel will assume Deputy Weld's post.
    • In the Game of the Year edition this is not the case, instead Deputy Steel will remain in the armory. However, Deputy Steel will still show up if the Lone Wanderer attacks Deputy Weld, as will Sheriff Simms.
  • If the Lone Wanderer enters the armory in Megaton, Deputy Steel will become hostile.



If one enters then exits the armory, he will follow them outside, thus causing the town to turn hostile towards the player character.

Notable quotes


Deputy Steel appears only in Fallout 3.

Behind the scenes

The line "What is your major malfunction, maggot?" is a reference to the 1987 movie Full Metal Jacket, in which it is is spoken by Gunnery Sergeant Hartman, right before he is shot by Private Lawrence ("Pyle").


PCPC Sometimes, upon fast traveling to Megaton, he will spawn right in front of the player character instead of inside the armory.[verified]

  1. Fallout 3 Official Game Guide Game of the Year Edition, p. 101: "Tinker Joe
    This wandering merchant sells a variety of junk, equipment, and weaponry, but also dabbles in scavenging and selling robot parts. He's built a good rapport with Wastelanders, and Sheriff Simms of Megaton is particularly happy with his purchase of Deputies Steel and Weld. He can currently be seen wandering the wastes with his robotic entourage, which includes an old Mister Gutsy army unit named Sergeant RL-3."

  2. Fallout 3 Official Game Guide Game of the Year Edition, p. 68: "Deputy Weld
    This RobCo Industry'sIn-game spelling Mister Gutsy robot has been reprogrammed to serve as an assistant to Sheriff Simms. Truth is, Simms is a fan of the Wild West (his dad used to read him stories when he was a kid). He took on the title of sheriff and named the robot his deputy mostly to live out his childhood fantasies."
