Sentry Bot

Sentry bot is a robot that appears in Fallout 3 and Fallout: New Vegas.

Background
 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 a push over, the sentry bot is a powerhouse, equipped with a sturdy armour plating, powerful weapons integrated into its chassis, and benefits from high mobility thanks to wheels mounted on its three legs.

Sentry bot


Sentry bots are one of the highest level robot characters, and are much more powerful opponents than protectrons, robobrains, and Mister Gutsy models. Their purpose is mainly to guard locations for some high profile characters and organisations, such as Repconn in Fallout: New Vegas. In Fallout 3 they will be more encountered in office buildings and pose a serious threat, wielding missile launchers and Gatling lasers. The Fallout 2 variants have a total different appearance, similar to super mutants and are able to walk.

Hardened sentry bot


A hardened sentry bot is a hardened version of the military sentry bot. They are Enclave affiliated, encountered along with hardened Mister Gutsies around the crashed vertibird in the Mojave Wasteland.
