Sentry bot (Fallout 3)

Sentry bots are a model of robot found in the Capital Wasteland in 2277.
==Background==
==Characteristics==
===Specifications===
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 and professional military personality, in contrast to the "gung-ho" patriotic personality of the Mister Gutsy.
===Gameplay attributes===
Sentry bots are the highest-level robots in Fallout 3; they are extremely durable, possessing as much health as a deathclaw but lacking a weak point that could 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 it is disabled. Although they are fast, they have a slow turning speed.
Sentry bots are among the toughest enemies in the game, and it is not uncommon to find sentry bots roaming the Capital Wasteland in groups of two or three at higher levels.
==Variants==
===Sentry bot===
Sentry bots come in many different guises, distinguishable by their paint, which shows their affiliation: Enclave, Brotherhood Outcasts, United States Armed Forces, etc.
===Enclave sentry bot===
Significantly darker in appearance, wearing matte black paint and dark red sensors, the Enclave model hosts improved systems. They appear at Raven Rock, as well as alongside certain Enclave squads found in the wasteland. In Broken Steel, they are encountered guarding sections of the Adams Air Force Base.
===Strike team sentry bot===
The most expensive option for recruitment in Operation: Anchorage is a winterized minigun variant sentry bot, costing 4 recruitment markers. In addition to the minigun variant, there is a Gatling laser equipped winterized sentry bot which was cut from Operation: Anchorage. 
===U.S. Army sentry bot===
Military robots from before the Great War, painted in the characteristic olive green of the U.S. Army. They can be encountered at Fort Constantine, the National Guard depot and occasionally wandering around the Wasteland.
===Presidential metro sentinal unit===
This unique sentry bot is encountered in Broken Steel at the end of the Presidential metro, near the metro to the Adams Air Force Base. It possesses the main fuse, which is needed to repair the nearby powerbox for the metro.
==Notable sentry bots==
* Sparky, found in the mobile base crawler.
==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."
* As with other types of robots, pulse grenades are especially effective against a sentry bot.
==Notable quotes==
Sentry bots possess an authoritative array of speech programming, though it mainly expresses its current programming out loud, much like the protectron. However, sentry bots have a deeper voice, instilling fear in all.

==Bugs==
* Outcast sentry bots will always spawn with the Gatling laser arm, despite resources for the minigun variants being present.
* 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 it is disabled.
