Protectron (Fallout 4)

Protectrons are a type of robot encountered in the Commonwealth in Fallout 4.

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 in turn 'blinds' the protectron, reducing its accuracy. If the protectron is inactive and a melee weapon is used, it will increase the chance of breaking the faceplate. 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" is a laser emitter that shoots a high-powered laser. The upper-body of a protectron can swivel up to roughly 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 engaging 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 thereafter.

Protectrons take reduced damage from shots directed at their head. Damage to the rest of their chassis is taken normally. When a protectron has lost a limb arm or leg, its audio system will also be damaged as the robot will speak but with some audio being scrambled.

Legendary protectrons, like other legendary robots, 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. Appears in green, blue and tan.

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. If the Sole Survivor is equipped with a Molotov cocktail, the protectron fire brigadier (or any protectron set to fire brigadier personality mode) will warn that the item they are holding is possibly a fire hazard and should be disposed of.

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. It can also appear in several different colors.

Utility protectron
This type can be distinguished by its yellow hazard color scheme with a light on their heads. It also has reinforced plating on their heads and backs, originally designed to protect it 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 attack with one or two nail guns (similar to the railway rifle), rapidly firing spikes that can kill even a high level player character with a single shot. It can also be spawned with two cargo loading arms that deal a large amount of melee damage. If the Sole Survivor is wearing a hard hat, the Construction Protectron will thank them for their compliance with the workplace safety rules.

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.

Protectron devil
Protectron devils are protectrons created by the Rust Devils. They are usually seen in packs with them or other protectron devils, but are less powerful than their base-game counterparts.

Protectron scourge
Protectron scourges are a tougher variant of the protectron devil. With a stronger melee attack and better laser damage. They are usually seen with Rust Devils or other protectron scourges.

Doom protectron
Doom protectrons are even tougher variant of the protectron devil, with proportionally stronger melee attack and laser damage. As with the other variants, they are usually seen with Rust Devils or other Rust Devil protectrons.

Protectron basilisk
Protectron basilisks are very high level encounters, with heavily armored chests and legs. They wield a railway rifle in their right arm and a flamer in their short left arm. The right wrist, arm and leg plates are spiked and serrated, causing their melee attacks on targets to leave them bleeding. The left arm and leg plates are reinforced to prevent much ballistic damage. Their heads are tall, like a spiked crown, with the skull of a human on the lower part. Their waist has a standard plate. They can be seen accompanying legendary rust devils, assaultron gorgons or Mister Handy war machines. If prepared, they can take down a behemoth or an integrated tankbot.

Protectron golem
Protectron golems are an even stronger variant of other rogue protectrons. With an even stronger melee attack and even better laser damage. Again, seen with Rust Devils and other protectron golems.

Nukatron
A type of protectron unique to Nuka-World. This protectron type shoots weaponized Nuka Cherry/Cola Quantum blasts instead of lasers. Its head and torso are combined into one, with a small screen on the upper torso presumably serving as its primary interface. The screen will sometimes play the "Park Safety Rules" promotional Nuka-World trailer, complete with audio. When this portion is scavenged and put on a robot workbench it removes the option of adding a separate head. Their voices are different than that of a regular protectron, and are much softer and slower.

Nukatron watcher
Identical in appearance to other Nukatrons, this variant has slightly higher stats and patrols the Galactic Zone.

Nukatron guardian
Identical in appearance to other Nukatrons, this variant has even higher stats and patrols the Galactic Zone of Nuka-World.

Nukatron defender
Identical in appearance to other Nukatrons, this variant has much higher stats and patrols the Galactic Zone of Nuka-World. They have three-and-a-half times the amount of health as the normal Nukatron.

Nukatron sentinel
Identical in appearance to other Nukatrons, this variant has the highest stats and patrols the Galactic Zone of Nuka-World. The Nukatron sentinel has four times more health than the normal Nukatron and shoots deadly bursts of weaponized Nuka-Cherry and Nuka-Quantum.

Galactron
Galactron are another variant of the protectron added in Nuka-World in the Galactic Zone. They have shiny white bodies, and the glass plates on their faces are gold.

Galactron usher
Galactron ushers are meant to provide security during different events.

Galactron watcher
Much like the protectron watcher.

Galactron guardian
Equal to protectron guardians, it is a re-skin of protectron guardian

Galactron defender
Beefed-up Galactron

Galactron technician
The Galactron technician is a Galactron in the projection booth of the Starlight Interstellar Theater. It will initially be in a charging station until the booth is entered.

Gunner protectron chef
This type of protectron is used by Gunners. The protectron chef wears a chef hat and is found in the Grandchester Mystery Mansion.

Gunner protectron
Protectrons that have been reprogrammed to be Gunner soldiers.

Protectron sheriff
Unnamed protectron sheriffs do not appear anywhere in Nuka-World, but they can still be spawned with the console. However, named protectrons Sheriff Eagle and Sheriff Hawk do appear in Dry Rock Gulch, manning the entrances as tour guides.

Personalities
In Fallout 4, each protectron 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 a player character's injuries and all variants will attack hostile NPCs on sight.

One other change is that subway stewards will insist on seeing the player character's subway token and will attack when if is not produced (regardless of whether one is present in their inventory or not). To give the subway token to the subway protectron, one must press the action button/key immediately following the bot's request. There is a window of approximately .8 seconds to give the coin (Video Demonstration). Alternatively, you can reverse-pickpocket a coin into the subway protectron's inventory - it will act as though you had given it the token in the .8 second window.

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