Sentry Bot (Fallout 3)

These Sentry Bots are 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 and a Missile Launcher), and three legs that end with wheels. The Sentry Bot is well armored and is capable of taking more than one direct rocket without being destroyed. One quick way to get past these metal hulks is to throw a pulse grenade at them which temporarily disables the robot. With this window of opportunity, unload on the robot without fear of reprisal. Another trick is to cripple its rocket launcher arm then fire from a distance or cripple the minigun arm and attack up close. When facing a solitary Sentry Bot, the combination of its slow movement and charge up time of its gatling lasers makes it possible for you to run around it when you are next to it without it being able to fire any shots at you. Or just get close and attack.

Appearances
This sentry bot model appears only in Fallout 3.

Tactics
Using pulse mines or grenades can be a huge help here, as Sentry Bots are highly resistant to small arms fire.
