Protectron (Fallout 4)

Protectrons are a type of robot encountered in the Commonwealth in 2287.

Characteristics
Unlike protectrons in previous games, the Commonwealth variant (except the police, medic, construction, and fire brigadier models) appears to have a transparent "faceplate" made of plastic or glass, with several blinking red lights visible behind the faceplate. It is possible to break this plate by fully damaging the head, which 'blinds' the protectron, reducing its accuracy. If the protectron is inactive and a melee weapon is used; it will increase the chance of breaking it. Previous versions had an opaque metal faceplate with a lit up glass dome on top.

Specifications
Protectrons have a glass dome on top of their heads that acts as an ocular lens which allows the protectron to scan its surroundings and act accordingly. In each "hand/claw" is a laser emitter that shoots a high-powered laser. The body of a protectron can swivel up to about 90 degrees to either side before having to step into a different position.

All protectrons come with a combat inhibitor mounted on their back that allows them to selectively target opponents. The combat inhibitor is generally left exposed, making it easy to disable when approaching a protectron from behind. When the combat inhibitor is crippled, the robot will fly into a frenzy, automatically targeting the nearest possible target, regardless of any previous affiliation.

Gameplay attributes
Compared to previous games, Protectrons have become significantly sturdier, particularly so against ballistic damage. However, by attacking their limbs, their more vulnerable insides will be revealed, which can be attacked for extra damage. If both of the Protectron's arms are destroyed, it will initiate a self-destruct sequence. The unit will begin to glow yellow and explode with the force of a mini nuke or a car shortly after.

Protectrons take reduced damage from shots directed at their head. Damage to the rest of their chassis is taken normally.

Legendary Protectrons will detonate violently, similar to a mini nuke blast, approximately two seconds after they are destroyed.

Protectron
The standard protectron can use its arm lasers to attack foes from a distance, or swat foes away for a substantial amount of damage when up close. If their arms are destroyed, they will initiate their self-destruct sequence and waddle toward their enemies in a last-ditch attempt to take them out.

Protectron medic
This model possesses two static electricity generators on its hands which are intended to be used as defibrillators. Protectron medics lack any ranged armament, but are deceptively powerful at melee range. They can attack targets with a staggering flurry of electrified slaps followed by a two-handed power attack.

Protectron fire brigadier
This protectron model is equipped with an internal "cryo-gun" which it can utilize in battle. Before the war, it was intended to stop fires. If any firearms are fired near it, then it will attack.

Protectron watcher
A somewhat stronger and more powerful variant of the original Protectron, this type can utilize dual laser arms in combat and a better melee attack. This Protectron is not to be messed with at a low level. It also has blue metal armor instead of a green-ish type.

Utility protectron
They may have one or two nailguns, similar to the railway rifle. They have an orange hazard color scheme with a light on their heads. They also have reinforced plating on their heads and backs originally designed to protect them from construction hazards but now protect them from whatever they may fight in the wastes. In close range combat, it will attack its target with simple punches. If its target is outside of melee range, it will instead utilize its nailguns, rapidly firing spikes that can kill even a high level player with a single shot.

Police protectron
Police protectrons are similar to the utility variants due to the fact that they have reinforced plating over their inner workings. They can be distinguished due to their blue paint job. These Protectrons utilize a stun gun or electric shock of some description in close range combat.

Protectron guardian
Similar to the Protectron and Protectron Watcher, this variant is the toughest type of any Protectron. It can use both dual rapid lasers, punches, and strong bashes. If you're at a low level, the best course of action would be to run from this Protectron.

Protectron devil
Protectron devil's are protectrons created by the Rust Devils. They are usually seen in packs with them or other protectron devils.

Protectron scourge
Protectron scourge's are a tougher variant of the Protectron devil. With a stronger melee attack and better laser damage, these types could be quite difficult to defeat at a low level. They are usually seen with Rust Devils or other Protectron scourge's.

Protectron golem
Protectron golems are an even stronger variant of other rogue protectrons. With an even stronger melee attack and even better laser damage, this protectron variant shouldn't be messed with at low levels. Again, seen with Rust Devils and other protectron golems.

Personalities
In Fallout 4, each protectron now has a programmable personality, so that it can serve a variety of roles: default, subway steward, law enforcement, fire brigadier, medical responder, and construction worker.

Generally, the personality does change the behavior of the protectron, and what it says as it patrols (construction workers will make comments about workplace safety and attack characters not wearing a work helmet, and medical responders will make comments about injuries and be generally passive until attacked). Medical responders will not heal player injuries and all variants will attack hostile NPCs on sight. The only notable change is that subway stewards will insist on seeing the player's subway token and will attack when it is not produced (regardless of whether the player has one in their inventory or not).

(NOTE: it is possible to give the subway token to the subway protectron. Timing is everything as the player will need to press the action button/key immediately following the bot's request. The player has a window of approximately .8 seconds to give the coin. Check out the YouTube video demonstrating the process .)

Personalities can be changed remotely without having to shut down the protectron.
