Sentry Bot (Fallout 4)

A sentry bot is a type of robot found in the Commonwealth in Fallout 4.

Characteristics
The Commonwealth variants of the Sentry Bot are similar in overall appearance to the ones encountered in the Capitol Wasteland and Mojave but are even larger (on par in height to a human wearing Power Armor), appear to a have bulkier construction and are substantially more resilient. Weapons of the sentry bot remains the similar as seen in Fallout: New Vegas, with a missile launcher and minigun being a typical combat load (except these miniguns appear to be unique 3 barreled variants chambered for the 5.56mm round) however alternate weaponry configurations such as dual miniguns can be observed as well, on top of which; Sentry Bots now have powerful melee attacks and a self-destruct function with equivalent power to a mini nuke. Although at least some variants appear to have four legs instead of three as seen in the previous versions. This may be due to two factors, firstly the Commonwealths rocky, hilly terrain requiring a greater amount of stability, and also to its sheer size and bulk, requiring a greater strength to make it operable. A similar variant to the Commonwealth sentrybots can be found in Fallout: New Vegas in the REPCONN museum as an antique four wheeled prototype.

Gameplay attributes
Sentry bots are some of the rarest and the most difficult robots to defeat - fast, agile, heavily armed and resilient enough to absorb a direct hit from a Mini nuke. After losing both main weapons they initialize their self-destruct sequence and charge at the player character. Even with their ranged weaponry intact, Sentry bots often charge into close combat to deliver powerful blows with their arms if one ventures too close, thus deterring attackers from any use of melee weapons. Since they explode on death with the force of a mini nuke, this tactic may prove even more dangerous to their opponent than their devastating long-range firepower.

Sentry bots are a good source of fusion cores, dropping at least two when they are destroyed, along with other valuable electronic components.

Low level players can defeat a sentry bot with hiding and running away until the sentry bot takes a few seconds to cool off revealing his weak fusion cores in its back. Firing any shot at them will instantly kill the sentry bot, however, the cool-down lasts only 2-3 seconds so one must act quickly, even after destroying a sentry bots fusion cores, it will still drop at least 2 fusion cores.

Controllable sentry bot
An inactive Combat sentry prototype MKIV can be found at the Robotics Disposal Ground. Inside the shed near the entrance to the facility there is a terminal that has a holotape loaded. Initiating the holotape on the terminal activates the sentry bot outside, after which it immediately starts to patrol the area. By ejecting the holotape from the terminal and using it in the player character's Pip-Boy the Sole Survivor can command the sentry bot to different locations in the Commonweatlh to clear of enemies, after which it will return to the junkyard. However, these locations are limited to nearby military sites.

Bugs

 * At Robotics Disposal Ground, the prototype sentry bot MKIV does not move once powered on.
 * Fast travelling elsewhere and sleeping can fix the problem. This is confirmed to work.
 * Using the Robotics Expert perk to disable and then re-activate the sentry bot can also fix the problem.
 * The bot will occasionally disappear when it is in patrol mode.

Locations

 * A Sentry Bot will attack the Sole Survivor after exiting the National Guard Armory.


 * A Sentry Bot named Sarge is encountered inside the armory of The Castle in the quest Old Guns.


 * Captain Ironsides will be found protecting the USS Constitution in the quest Last Voyage of the U.S.S. Constitution.


 * A Sentry bot will be seen guarding the outisde of Cabot House.
