Robobrain (Fallout 3)

Robobrains are robots 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 business companies, in use by groups such as the Brotherhood of Steel, Enclave, Brotherhood Outcasts, or even simply wandering the wastes. There are two variations of the robobrain model. 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 model that was used in the civilian sector, these are more seen wandering the wasteland at random. Later, with the Point Lookout add-on, a new variation of the robobrain called the 'robobrain sentry' is introduced. Their combat skills are the same, but they have 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. On the back of every robobrain is a combat inhibitor which, if crippled, will cause the robobrain to frenzy, attacking everything indiscriminately.

Another weapon that robobrains possess is a built-in Mesmetron. This attack does not cause much damage, but if it manages to hit, it 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, as that is where the robobrain is at its weakest.
