Effects of player's actions

  • Deputy Steel will replace Deputy Weld if it is killed (unless Broken Steel is installed).
  • If Megaton is destroyed during The Power of the Atom quest, Deputy Weld's faceplate will survive the atomic explosion and continue to welcome people to Megaton (albeit in a garbled manner) and state that "the bomb is perfectly safe".
  • Deputy Weld can be deactivated by hacking a computer terminal in the Megaton armory. A skill of 75 Science is required to deactivate both deputies.
  • Killing Deputy Weld results in a loss of Karma, and it will respawn after a while.

  1. Lone Wanderer: "You're a liar, Moriarty. I know where I grew up."
    Colin Moriarty:"Aaahhhh. I see. You know, I heard about the brainwashin' that goes on down there. From some other fella, escaped, oh... five years back. 'All hail the Overseer! We're born in the Vault, we die in the Vault!' And all that other assorted lunacy. Kid, you've got better programming than our own Deputy Weld. You'd best wise up quick. Wouldn't want anyone... takin' advantage of ya. Hmm?"

  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
    A RobCo Industries Protectron robot that guards the entrance to Megaton, Weld talks like a 50s robot but probably has some cowboy lingo programmed into him. He stays at the front gate and offers any traveler some platitudes."
