Acting as support fire

I'd like to point out, that despite their name, they often are acting as support fire to troops, (operation: anchorage you have the opertunity to get a sentry bot to support you, or outcasts using them in the heat of combat) as opposed to just gaurding a door

Outside of their overall appearance in the games, how do we know that the sentry bots are different between the two coasts? Mr. Sully 20:45, 3 September 2008 (UTC)

Well, the two sentry bot models are clearly different, even if their function is similar, and because the only name for them in the games is this generic one, I used disambiguation. Unless this Sentry Bot is the same as Mister Gutsy. Ausir 21:03, 3 September 2008 (UTC)
Thanks, Ausir. I was just wondering if there was some info I missed somewhere else about the models of the bots! Mr. Sully 02:58, 4 September 2008 (UTC)

Has anyone else noticed this bot being especially suicide-prone compared to other enemies? From what I've seen, sentries are entirely too fond of waiting till you're at point blank range to fire a missile, getting caught in the blast themselves, and won't hesitate to fire inside the cloud of a flammable gas leak. Is this a quirk of my playing experience, or is this normal behaviour that may be noteworthy to mention for confrontation tactics? -- 17:12, 22 November 2008 (UTC)

Weak Point

If you can sneak behind them you can sneak attack critical 1 shot them on the "combat inhibitor" panel using a combat shotgun. Little panel right in the middle of the back with a little electric symbol.

The combat inhibitor just acts the same as an insects antennae does in this game, take it out and it frenzies attacking friend and foe alike. Im not sure if attacking this spot does more damage or not, i rarely target these areas unless im sniping an enclave camp and i happen to see a robot. Its quite funny shooting a sentry bot's combat inhibitor and watching it tear enclave soldiers up lol.--Greig91 15:43, 26 April 2009 (UTC)

Does anybody happen to know the base ID for the Outcast Sentry Bot?

Um aren't the arms on the Sentry Bots weak points? Whenever I engage one, I always aim for the arms. On Very Hard, 4 critical shots (with A3-21's Plasma Rifle) to the arm can take its health down very low; if the first critical was a sneak critical, that robot is as good as dead. JCnightstrike7 05:29, 17 August 2009 (UTC)

Is there a way to definitely confirm what (if any) part of the enemy takes increased damage, and if so, should that info go on the page? - 17:46, February 5, 2010 (UTC)

Tactics Moved From Page

  • One quick way to get past these metal hulks is to throw a pulse grenade at them which temporarily disables the robot (though sometimes it seems to make the robot go faster). With this window of opportunity, unload on the robot without fear of reprisal.
    • In my case, Pulse Grenades do ridiculous amounts of damage. Two, maybe three is enough to take one out.
      • Two pulse mines did it for me. Torinir 09:10, 16 June 2009 (UTC)
  • Cripple its missile launcher arm then fire from a distance.
  • Cripple the minigun arm and attack up close.
  • Shooting them in either arm seems to do more damage than anywhere else.
  • When facing a solitary Sentry Bot, the combination of its slow movement and charge up time of its gatling lasers/minigun makes it possible for you to circle strafe around it without it being able to fire any shots at you.
  • Sentry Bots have high resistance against fire based weapon such as Flamer. However, Shishkebab surprisingly deals incredible damage to Sentry Bots. But if you have your flamer pointed at the center or the head, excluding the VATS it will do more damage, if you have the Burnmaster, it will be more effective
  • Due to their innate ability to ignore enemy DR, Deathclaw gauntlets are also an ideal weapon, and can destroy a Sentry Bot with just a few strikes.
  • Provided you can close distance, the best tactic is to use the Shishkebab or Deathclaw gauntlet and strafe around it in a circle. Change directions from clockwise to counterclockwise to confuse it even more, and it will never fire a single shot.
  • When facing a Sentry Bot with conventional weaponry only, keep in mind that its weapons are mounted relatively low on its chassis and far from its center. This can allow you to make attacks on the Sentry´s body from above or from behind cover while blocking the Sentry´s line of fire.
  • Due to its slow movement speed, if you can get behind it you can melee it to your hearts content.
  • Players who possess a high enough critical strike chance, as well the Victory Rifle can easily take a sentry bot down without letting it fire a single shot, as critical strikes will cause a knockdown, but due to the sentry bots tripod design, they will often just be standing, allowing easy targeting of the hardpoints.

It should be noted that crippling it's weapons will NOT disable them but rather greatly reduce their accuracy.

  • On Xbox 360, if you can approach a sentry bot in stealth mode and it detects you, you can rapidly press A and the sentry bot will hesitate atttacking you and say a single phrase, giving you time to gun it down as long as you keep pressing A.

It's a bird... It's a plane... It's a Sentry Bot!!!

  • Yet another bug along the lines of the "flying Deathclaw" or "rocket-propelled Yao Guai". Ok, I was forcing Butch to get over his fear of radroaches by making him fight the Roach King and his minions by himself, either that or I was just reinforcing his fear (lol), anyway after the Roach King and all his roaches were dead as I approached his "throne" I heard minigun fire off in the distance. I thought at first that it was the King's minigun's sound effect still going on due to some sound bug, but he'd never actually fired the thing, Butch got him with one headshot before the guy could react and it sounded very far away beyond a hill that I couldn't see over. Suddenly a Sentry Bot flew over the hill at a very high speed about 25 feet over us and landed a good football field away and the minigun sound immediatly stopped. Scared the hell outta me, lol. I looked over the hill to see if there had been a fire-fight going on that caused this, but there wasn't anyone... just me and Butch. The next day it happened again while fighting raiders, even had the minigun sound effect and once again it just came out of nowhere, but this one landed pretty close to me. Hasn't happened since but on very rare occasions I hear that same minigun in the distance, I sometimes only notice it right before it stops as it is sorta quiet. Has this happened to anyone else or are they just attempting flight in my game? Snakewyvern 09:33, February 9, 2010 (UTC)
  • Who cares, that's just goddamn awesome! Pog 14:11, July 9, 2010 (UTC)


if you cripple the arm can they still use the weapon associated with that arm

Four Legged sentry bot model

Shouldnt that picture be moved to the New Vegas version of the Sentry Bot?—Preceding comment was unsigned. Please sign your posts with ~~~~!

Yep. I just took it off.JASPER//"Do you like hurting other people?"UserRichard.png 21:57, October 27, 2010 (UTC)


The picture in the gallery appears in Fallout: New Vegas, not Fallout 3 (unless I'm mistaken). Should it remain on the FO3 page or be removed? I'd like an opinion before I remove it, in case I ruffle any feathers. Yes-Man 04:57, June 29, 2011 (UTC)

It's cool, Nitpicker removed it. Thanks Yes-Man 05:02, June 29, 2011 (UTC)

Sure. :3 Nitty Tok. 05:24, June 29, 2011 (UTC)


The 10mm SMG allows your character to go in between the bot's arms and fire while taking little damage. You have to keep running at the bot even though you are pushing against it. Not for when facing multiple opponents. 05:45, July 27, 2011 (UTC)
