Sentry bots are a model of robot found in the Capital Wasteland in 2277.

BackgroundEdit

Sentry bots (military serial numbers SB-XXXX) are security robots made before the Great War with the express purpose of participating in the heaviest of firefights during war. Where the Mister Gutsy is a hovering platform with modest armor plating, and the protectron was originally designed for protecting business premises, the sentry bot is a powerhouse, equipped with sturdy armor plating, powerful weapons integrated into its chassis and high mobility thanks to wheels mounted on its three legs.

CharacteristicsEdit

SpecificationsEdit

Sentry bots have two arms equipped with powerful weapons: a minigun or Gatling laser on their right, and a missile launcher on their left. All models have wheeled, tripod legs.

They are programmed with an authoritative, professional, military personality, in contrast to the "gung-ho", patriotic personality of the Mister Gutsy.

Gameplay attributesEdit

Sentry bots are extremely durable, possessing as much health as a deathclaw but with greater Damage Resistance. Also, they do not have a weak point that can be targeted for additional damage. In fact, their heads are more durable than their torsos, though targeting the head yields a greater chance of a critical hit. Like other robots, sentry bots are equipped with a combat inhibitor and will frenzy if the inhibitor is disabled. Exploiting this weakness can be helpful in dispatching other enemies, since sentry bots are among the most powerful foes in the game. Although they are quite fast, they have a slow turning rate, which can be used to the player's advantage.

Sentry bots are the highest-level robots in Fallout 3, and are much more formidable opponents than protectrons, robobrains and Mister Gutsies.

Sentry bots are among the toughest enemies in the game and present a serious threat to any low level player unlucky enough to encounter one. It is not uncommon to find sentry bots roaming the Capital Wasteland in groups of two or three at higher levels. These robots are mobile fortresses; their high level of health and lethality makes them the preeminent fighting machines of the Capital wastes.

Presidential metro sentinal unitEdit

This unique sentry bot is encountered in Broken Steel, at the end of the Presidential metro, near the metro to Adams Air Force Base. It holds the main fuse, which is needed to repair the nearby powerbox for the metro.

NotesEdit

• While the head of a sentry bot is the smallest part of its body, it has an increased chance for a successful hit in V.A.T.S. even when at great distances with any sort of firearm (it can be difficult to select the head on the PC version).
• Using the Robotics Expert perk, on a hostile sentry bot, the player gets 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."
• 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, allowing you a limitless supply of scrap metal, missiles, and whatever else it may carry.
• Upon finishing The Superhuman Gambit, the Mechanist's robots will remain in the street (if something destroyed them previously). One or both will be sentry bots.
• There are two sentry bots in the Control Room of Raven Rock guarding the entrance to the room where President Eden can be found, and 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."
• As with other types of robots, pulse grenades are especially effective against a sentry bot.
• Sentry Bots turn quite slowly. If the player can get to their rear and continually adjust your position so as to not be in their front arc, they can be safely defeated with melee (or unarmed) attacks.

Notable quotesEdit

Sentry bots possess an authoritative array of speech programming, mainly expressing its current programming out loud, much like the protectron. However, sentry bots have a "deeper" voice, instilling fear in all.

• "Warning: use of lethal force is authorized!"
  
• "Security lockdown in effect. Hostile target acquired!"
  
• "Adding target to threat matrix!"
  
• "Hostile detected. Commencing neutralisation."
  
• "Alert! Non combattants are advised to leave the area. Security sweep in progress. Lethal force may be used without warning."
  

BugsEdit

• ps3 xbox360 pc Outcast sentry bots will always spawn with the Gatling laser arm, despite resources for the minigun variants being present. ^[verified]
• xbox360 ps3 If you disable the sentry bot (using the Robotics Expert perk), the sentry bot will be disabled but will keep on performing the animation where he is disabled. ^[verified]
