Feral ghoul

Feral ghouls (also known as mindless zombies, ghoul crazies, feral necrotic post-humans, zombies or simply ferals) are ghouls that have lost their ability to reason and have become aggressive. This has caused much discrimination toward other ghouls which have retained their mental faculties by human wastelanders.

Biology
 The brain structure of a feral ghoul indicates that the regenerative ability of the neurological system that affords "normal" necrotic post-humans their longevity does not extend into the higher reasoning functions of the brain itself. This condition is referred to as "ferocious post-necrotic dystrophy", according to the ghoul physician Barrows. Despite the apparent lack of the higher reasoning they once had as humans, some are capable of semi-intelligible speech, as the Vault 34 security officers will occasionally growl out understandable phrases similar to the trogs of The Pitt, meaning that their vocal chords are still relativity intact, as is the part of the brain which controls speech.

As the reasoning and critical thinking portions of a ghoul's brain deteriorate, the ghoul subject becomes increasingly hostile, giving in to a carnal need to feed. It remains unclear exactly what precipitates this change in neurobiology and psychology, but anecdotal evidence seems to indicate that non-social ghouls, or those in isolation, are more prone to the condition.

It is also quite possible that this is a gradual process, meaning that eventually all ghouls will succumb to this condition. However, considering the existence of ghouls that have been born prior to the Great War two centuries ago, it is quite possible that this theory is bunk, or that the rate of degeneration is dependent on the individual affected and surrounding environmental factors.

As with normal ghouls, ferals are not only extremely resistant to radiation, they are actually healed by it, as can be seen when a glowing one uses its' radiation blast nearby other ghouls. M.A.R.Go.T. also states that feral ghouls have no internal body heat.

Behavior
Feral ghouls often cluster together in dark, cool environments, like sub-basement-levels or underground areas, only occasionally leaving their normal hunting grounds for time in the open air. However, the myth that ferals fear light is false. Occasionally, the player may encounter one or two ferals out in the open. Isabella Proud's research seems to confirm that feral ghouls do not fear or avoid light. One prime example is Warrington Trainyard. Another good example is the Mojave Wasteland, where almost all feral ghouls can be found outdoors during the day.

Frequently, ferals of all types will wander from place to place, stopping at fallen prey to feed, but will immediately attack any and all non-ghoul creatures they come across. They will often sniff, screech, or lash out at other ferals. Upon detecting a non-ghoul, most ferals will make a high-pitched gurgle or screech, and set out to search the area. Upon sighting prey, they will often scream once more, alerting any nearby ghouls, and attack. There is no rank or pecking order to these attacks; all attack at the same time in a rampant onslaught. Because of this in enclosed areas like Vault 34, it is very easy to get overwhelmed. Feral ghouls mainly attack with their hands, slashing and smashing in an insane fury. Some feral ghouls can be seen to use weapons, such as the trooper ghouls in Camp Searchlight, likely indicating that they have only gone feral recently.

Feral ghouls are not very smart but the fact that they seem to move in packs and stay near irradiated areas shows that they have some form of intelligence. However, this may simply be a form of survival instinct.

Ghoul mask
One interesting note with ferals is that they seem to be fooled by very rudimentary means. The ghoul mask, seemingly nothing more than the hollowed-out head of a ghoul or several pieces of a human head stitched together, still seems to deter ferals from attacking.

When wearing the ghoul mask (or using a Stealth Boy) the player can observe relaxed feral ghouls' actions, including twitching, bending down, having fits or sniffing the air. If you are wearing the ghoul mask, ferals will often turn their head to the side and stretch their necks when you come near them, as if they are confused.

However, it is not advised to get to close while wearing the ghoul mask, as stated by Roy Phillips when given the mask, if you get close enough to the ghouls they will "sniff" you out and attack you, even if you have the mask on. Regardless of this advice, the ghouls will not attack unless the player removes the mask or provoke them.

Feral ghoul


Feral ghouls (also known as mindless ghouls or ghoul crazies) are the basic feral ghoul variant, wearing only a pair of tattered shorts and noticeably weaker than standard human opponents, they are easily dispatched with one or two headshots from any decent weapon or a solid hit from a decent melee or unarmed weapon. Despite their shrill noise and remarkable speed, they are only truly a threat when they have the advantage of numbers, or when the player character is at a low level. Some feral ghouls come in different colors as well as different types. The colors are different depending on how the human looked before turning into a feral ghoul.

Feral ghoul roamer
Some feral ghoul roamers in the Capital Wasteland wear what appears to be the remains of old combat armor, and are somewhat tougher than standard feral ghouls, requiring more damage to be dealt to put them down. It is possible that roamers are ghoulified U.S. soldiers since tattered remains of combat armor are strapped to their bodies. However, in the Mojave Wasteland, ghoul roamers appear no different than the standard feral ghoul. They are not very common but can be found in groups of 2-5 in places containing lots of ghouls (Museum Of History etc.)

Glowing one
Glowing ones or luminous necrotic post-humans are ghouls who absorbed so much radiation that they glow in the dark, being living conduits of radiation. In daylight they simply appear to be incredibly pale feral ghouls, but in darkness they glow with a vivid yellow-green hue, their opaque skeletons clearly visible as in an X-ray. Approaching a fallen glowing one can cause minor exposure to radiation, so they can still be dangerous to normal humans even after their death.

They are often considered outsiders even by other (non-feral) ghouls, they are also one of the rarest of the feral ghouls. While there are many glowing ones that kept their normal human intellectual abilities in the Core Region, it seems that nearly all of them in the Capital Wasteland and the Mojave Wasteland have become feral.

The Capital Wasteland and some Mojave Wasteland glowing ones can also emit an incandescent wave of radiation at will from their bodies, which they use to heal themselves and any surrounding ghouls while damaging their enemies. Even though being considered outcasts, other feral ghouls seem to follow them, as they are attracted to the lethal doses of radiation the glowing ones emit from their bodies.

All glowing ones in Fallout 3 and Fallout: New Vegas are feral with the exception of Jason Bright.

In Los, the glowing ghouls are among the members of the Church of the Lost, a ghoul cult dedicated to protection of the Secret Vault. Interestingly, they are less affected by radiation than their comrades from the Capital Wasteland and the West Coast's Core Region.

Feral ghoul reaver


Feral ghoul reavers appear in the Fallout 3 add-ons Broken Steel and Point Lookout and also can be found in Fallout: New Vegas in the Mojave Wasteland. They are much more combat-worthy than other ghouls and wear what appears to be the remnant of metal armor. They also have the ability to rip radioactive gore off themselves and hurl it like a grenade. Aside from the damage they can inflict, they also have great endurance and boast one of the highest HPs in the game, being able to survive even attacks from the Fat Man. Their lunge attacks (much like a deathclaws') can send the player a good distance back, and can even have a high level player crippled and dead in a short amount of time.

Swamp ghoul


Swamp ghouls are feral ghouls which exclusively inhabit the swamps of Point Lookout. Swamp ghouls wear a tattered pair of shorts commonly worn by tribals, hinting that they were once tribals who didn't eat their punga fruit. They are found in massive numbers in and around Turtledove Detention Camp. They exhibit characteristics similar to those of normal feral ghouls, but their skin's general appearance is more of a gray color and they are also considerably weaker. However, the swamp ghouls tend to be in greater numbers.

Endless walkers


The Endless Walk is the punishment in which a ghoul from the Reservation is stripped of every worldly possession, including clothing, and sent marching into the wasteland. No ghoul has ever come back from the Endless Walk (note that after being exiled from the Reservation, Otto Stead was saved by Governor Dodge at Hoover Dam). Another source of Endless Walkers in the Boulder area is the Crater, the remains of what was once NORAD.

Not all endless walkers end up scorpion food, at least not at first. On those rare occasions when one survives more than one year in the wasteland, they turn into wandering, voracious creatures on an endless quest for flesh. Due to their prolonged, open exposure to the desert sun, high radiation, and other hardships of the wasteland, these unfortunate ghouls, who were banished naked from the Reservation, look like walking, sun bleached chunks of beef jerky. Their constant exposure to the hot sun and high levels of radiation has caused their skin to toughen into natural, hardened leather, but at the same time, their ability to reason has been completely lost.

Appearances
 Feral ghouls appear in Fallout (in random encounters, as "mindless ghouls"), Fallout 2 (as "ghoul crazies"), Fallout 3 (where they are actually named "feral ghouls" for the first time), Fallout: New Vegas, Fallout: Brotherhood of Steel and were due to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios (as "endless walker").
