Robobrain (Fallout 3)

The Robobrain is a type of robot found in the Capital Wasteland

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

There are three variants of the Robobrain. The first, and most common, is the military variant used by the U.S. Army, recognizable by its green paint scheme with a prominent white serial number stenciled on the front. 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 introduces the final variant, the Robobrain sentry, which is identical in the appearance to the civilian model but possessing significantly more health.

Robobrains are substantially more durable, accurate, and dangerous than the more commonly encountered Protectron. Armed with a pair of integrated lasers each 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 headshots. 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 it may instantly cripple the head of the player character (dealing 1000 damage to the body part) and inflict 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.
