Sentry bots are a type of robot encountered in Appalachia.

Background[edit | edit source]

This section is transcluded from Sentry bot. To change it, please edit the transcluded page.

The heaviest class of combat robot in the United States military, the sentry bot sacrifices speed and maneuverability for sheer resilience and overwhelming firepower. The sentry bot had become a standard piece of military equipment by at least 2063, with prototypes existing further back.[1] The assaultron is designed for melee combat, and the Mister Gutsy is a jack-of-all-trades. The sentry bot's purpose is to engage the enemy at range with a variety of weapons, including miniguns, Gatling lasers, rocket launchers, and even back-mounted cluster grenade launchers. At the same time, its thick armor and multiple redundant systems allow it to survive extended engagements. It's commonly considered to be one of the most dangerous robots ever created and RobCo Industries' finest fighting robot. Late models are also provided with the ability to self-destruct to prevent the enemy from recovering the robot.[2] Early sentry bot models were issued serial numbers in the SB-#### format (model, then serial), with later models transitioning to the standardized alphanumeric registration in the ABC-###### format.[3]

Characteristics[edit | edit source]

The Appalachian variant of the sentry bot is identical to the variant of sentry bot used in the Commonwealth. They have a bulkier construction and are more resilient than their counterparts in the Capital and Mojave Wastelands.[clarification needed] The typical weapons loadout of the sentry bot remains the same as seen in other regions, with a missile launcher and minigun, which is a three barreled variant chambered for the 5.56mm round. However, variants also use alternate weaponry configurations such as dual miniguns.

On top of their formidable ballistic and explosive weaponry, sentry bots have powerful melee attacks and a self-destruct function with equivalent power to a mini nuke. Despite their bulky armor and appearance, they are capable of fast movement and traversing rough terrain. In addition, a sentry bot's entire torso is capable of rotating independently of its legs, functioning akin to a turret, and allowing it to move in one direction while shooting in a different direction, against targets in any direction. Sentry bots also use Mecanum wheels that allow it to strafe right and left without having to turn.

Gameplay attributes[edit | edit source]

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 will 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.

All variants explode on death with the force of a mini nuke, which can cause significant damage to surrounding opponents. All legendary robotic enemies explode upon death. This explosion does not override the sentry bot's built-in self-destruct, which means a legendary sentry bot will explode twice, occurring after a short delay of a few seconds.

Should a sentry bot engage the player character for too long, they will eventually enter a cooldown period, blasting steam out of their back and exposing their dual fusion cores. Hitting exposed fusion cores causes additional damage. After one explodes, the sentry bot becomes a charred, blackened version of itself, and is safe to loot then for various scrap, ammo, and potential fusion cores.
