Sentry Bot (Fallout 3)

FO76 publicteam xpd.pngFor an overview of the topic, see Sentry Bot.

Alert! Noncombatants are advised to leave the area. Security sweep in progress. Lethal force may be used without warning.

Sentry Bots are a model of robot found in the Capital Wasteland in Fallout 3.

Background

The sentry bot was created to provide security through overwhelming firepower.[1] The sentry bot has a cool down phase after attacking, which results in its fusion core being vulnerable.[1] The combat drone utilizes a variety of heavy weapons systems and explodes upon death.[2] Sentry Bots use a minigun or Gatling laser on the right arm, and a missile launcher on the left. The robots have a combat inhibitor on their back that will cause it to frenzy if damaged. Sentry Bots possess judicial circuits, which are employed when they witness a murder or thievery, and will hand out death sentences to the criminals they find.[3]

Gameplay

Sentry Bots have paint jobs that shows their affiliation, including Enclave, Brotherhood Outcasts, and United States Armed Forces.

Notes

  • Using the Robotics Expert perk on a hostile sentry bot will give the player the option to talk to it or shut it down. If the talk option is selected, the bot will only say "Do not interfere with security operations." The player can also talk to a sentry bot without the perk, which will lead to the same dialogue.
  • A sentry bot can be found in Big Town. Fixing it is one of the options for helping the residents fight off the attacking Super Mutants after the completion of the quest, Big Trouble in Big Town.
  • There is a sentry bot guarding the Citadel which will disappear after the Take it Back! quest is finished. If destroyed prior to this, however, it will respawn.
  • Upon finishing The Superhuman Gambit, the Mechanist's robots will remain in the street if they were destroyed previously. One or both will be sentry bots at higher levels.
  • There are two sentry bots in the control room of Raven Rock, guarding the entrance to the room where President Eden can be found. They will attack the two hostile Enclave soldiers, killing them. Like other sentry bots, they can be shut down, but destroying them grants the player with only 1 experience point and negative Karma. These sentry bots also have a unique piece of dialogue, saying, "The president will see you now."
