Sentry Bot (Fallout 3)

Sentry bots are robots found in the Capital Wasteland in 2277.

Characteristics
Sentry bot 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 Mister Gutsy model.

Sentry bots are extremely durable, possessing as much health as a deathclaw and greater damage resistance, in that unlike a deathclaw they do not have a "weak point" that can be targeted for additional damage. In fact, their heads are actually more durable than their torsos. Like all other robots, sentry bots are equipped with a combat inhibitor, and will go into a frenzy if it is disabled. This can be helpful in dispatching other enemies, since the sentry bots are among the most powerful foes in the game. Despite its seeming bulk, the sentry bot is unusually fast, but has a very slow turning rate which can be exploited.

Sentry bots are the highest level robot non-player characters in Fallout 3, and are much more powerful opponents than protectrons, robobrains, and Mister Gutsy models.

Sentry bot
Sentry bots are among the toughest enemies in game and present a serious threat to any low level player unlucky enough to encounter one. It should also be noted that it is not uncommon to find sentry bots roaming the Capital wastes in packs of 2-3. Possesing a Missile Launcher in one arm and a gatling laser or minigun in the other, these robots are mobile fortresses. With their surprising levels of health and unique ability to actually dispatch the creatures they target, these robots are head and shoulders above the other machines of the Capital wastes.

Sentry bots can come in many different apperances, most notable is their paint, which is effected by their affiliation (Enclave, Brotherhood Outcasts, United States Armed Forces, etc.).

Notable quotes
Sentry bots possess an authoritative array of speech programming, mainly expressing its current programming out loud, much like the protectron. However, sentry bots have a "deeper" voice, instilling fear in all.
 * "Warning. Non-combatants are advised to leave the area. Security sweep in progress. Lethal force may be used without warning."
 * "Alert. Hostile detected. Lethal force authorized for all units."
 * "Do not interfere with security protocols."
 * "Have a nice day."

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, the sentry bot will be disabled but will keep on performing the animation where he is disabled.
