Robobrain (Fallout 3)

The robobrain is a type of robot found in the Capital Wasteland in 2277.

Gameplay attributes
Robobrains are a fairly common sight in the Capital Wasteland. They can be found in many abandoned buildings of pre-War companies, in use by groups such as the Brotherhood of Steel, Enclave, Brotherhood Outcasts or even simply wandering the wastes.

There are three variants of robobrain. The first, and most common, is the military variant used by the U.S. Army. It is painted green and has a serial number, they are more commonly used by various factions. Less common is the gray-colored civilian model, seen wandering the wasteland at random. The Point Lookout add-on introduced the robobrain sentry, identical to the civilian model but with significantly more health.

Robobrains are substantially more durable, accurate, and dangerous than the more commonly encountered protectron. Armed with a pair of integrated lasers roughly equal in power to a laser pistol, the robobrain is a moderate threat, though easy to damage due to its size and extreme vulnerability to head shots. Every robobrain has a combat inhibitor on its back, and if the inhibitor is crippled, the robobrain will frenzy and attack indiscriminately.

Robobrains also possess a built-in Mesmetron. This attack does not cause much damage, but instantly cripples your head (dealing 1000 damage to the body part) and gives you the concussion status effect, resulting in blurred vision, hindered accuracy, and -4 base Perception. This is used to discourage melee and close-ranged attacks, where the robobrain is weakest.
