Sentry Bot (Fallout 3)

The Sentry Bot (military serial numbers SB-XXXX) is a military robot model made before the Great War. A different Sentry Bot model was used in military bases in California, while this one has been seen mainly in the Capital Wasteland. They have two arms that end with deadly weapons (a Minigun or Gatling Laser on the right arm, and a Missile Launcher on the left arm), and tripod legs with wheels.

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

Sentry Bots are the highest level robot NPCs in Fallout 3, and are much more powerful opponents than Protectrons, Robobrains, and Mr. Gutsys.

Statistics

 * Level: 12
 * Health: 500

 * Combat skill: 80

Sentry Bots are extremely durable and take significant amounts of small arms or energy weapons fire, or even multiple missile shots, to destroy. They have the same very high amount of health as a Deathclaw. Additionally, unlike Deathclaws, they do not have a "weak point" that can be targeted for extra damage. They do not take additional damage from headshots, and in fact take reduced damage from shots to the head or legs compared to shots to the torso or arms. Pulse grenades, however, can usually destroy them in a single blast.

Appearances
This sentry bot model appears only in Fallout 3. A similar robot appears in Fallout 2 also armed with minigun and missiles, however with different design.

Quotes
Sentry Bots possess an authoritative array of speech programming, mainly expressing it's current programming out loud, much like the Protectron. However, Sentry Bots have a "deeper" voice, instilling fear in all.
