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 could be seen in many abandoned buildings of various business companies, in servitude to groups like Brotherhood of Steel, Enclave, Outcasts or even wandering the wastes, damaged and dangerous. 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. Less commonly, there is the gray-colored model that was used in the civilian sector. 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 robot. Armed with a pair of integrated laser weapons 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.

One thing to note is that robobrains possess a built-in Mesmetron device. 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 attack is used to discourage melee and close-range combatants from getting too close, as that is where the robobrain is weakest. When fighting one keep moving, and be ready to inject yourself with a stimpak at a moments notice.
