Robobrain (Fallout 4)

Robobrains are a type of robot mentioned in Fallout 4. They physically appear in the game in the add-ons Automatron and Far Harbor. Robobrains can then be encountered in the Commonwealth and on the Island in 2287, respectively.

Background
Before the war, there was an underground facility hidden by a RobCo building that soled computer terminals. This facility was hidden underneath Boston and had the sole purpose of building robots for the war effort. The biggest manufacture robot in the facility was the RoboBrain.

The RoboBrain was first made by the worst of the worst prisoners getting taken to observation chambers, they would have lots of drugs pupped into them and fed an odd diet, all for an experiment. They would then get reduced to their brain with machinery and a robotic eye keeping them alive. If they were blood thirst enough the staff would wipe their mind to make mindless fighting machines and then put their brains onto metal bodies.

If the RoboBrain didn’t do what they said without question, they would be incinerated, most were successful but also a lot got scrapped. The RoboBrains remained in this facility as the Great War started, stopping them from being used. 210 years later the Mechanist repurposed them to be high ranking members of her robotic army to protect the Commonwealth, the RoboBraains thought putting humans out of their misery was the only way to save humanity.

Specifications
Unlike in previous Fallout games, the robobrain from Fallout 4 appears to have a built-in eye in front of the brain.

Robobrain
The basic variant is the weakest and most common robobrain, with one of the manipulators replaced with a Tesla coil that fires an electrical discharge that arcs between targets. All robobrains are capable of a "mesmetron" attack that looks similar to the blast from a gamma gun. This blast is blue in color, staggers the player character and makes them black out briefly upon contact with the blast. Mesmetron blasts increase in frequency the more difficult the robobrain encountered.

Servomech robobrain
An improved version of the basic robobrain, the most notable feature being an increase in health.

Integrated robobrain
A stronger and more robust variant of the original robobrain, with increased health pool and damage resistance.

Cybermech robobrain
This version of robobrain is the second most powerful variant. Cybermechs come equipped with their standard claw for melee, but an abnormally powerful robot modification, the unstable Gatling laser. Besides this change in weaponry, some kind of robot armor, perhaps primal plates, have been added to reinforce the chassis of the robobrain. This version of robobrain has a 150 point boost in health over the integrated robobrain, and is fully capable of rotating its torso independently of its treads, leaving almost no way to flank it. It may also strafe the player character with its rotating torso and treads, leaving stationary combat ill-advised.

Quantum robobrain
The most deadly version of robobrain built by the Mechanist. The Quantum Robobrain has been highly modified with hydraulic armor, making damaging limbs or destruction of the robot nigh impossible without heavy weaponry. Additionally, Quantum Robobrains are capable of tactics such as basic cover systems and high-speed strafing. They are more accurate with their unstable Gatling laser than their Cybermech counterparts, and the frequency of the mesmetron attacks leaves the player character almost completely blind. This foe is cunning, cruel, and leaves almost nowhere to hide from their unending assault.
