Feral Ghoul (Fallout: New Vegas)

Feral ghouls are creatures found in the Mojave Wasteland

Feral ghoul
Feral ghouls are the basic feral ghoul variant, wearing only a pair of tattered shorts.

Feral ghoul roamer
The feral ghoul roamer is more dangerous than the regular feral ghoul.

Feral ghoul reaver
Their Hit Points in the game vary. At lower levels, they are merely slightly stronger than a feral ghoul roamer, but are weaker than a glowing one. Some can be found at the old nuclear test site, outside Hell's Motel at Mesquite Mountains crater and one will always spawn inside the sealed sewers, regardless of the Courier's level.

Feral trooper ghoul
Feral trooper ghouls are former NCR troopers that have become feral. They still wear their NCR trooper armor, as they were on duty when the radiation was released from inside Camp Searchlight by Legion soldiers. There are a total of nine of these, and killing them is part of the quest We Will All Go Together.

Glowing one
These ghouls are found often at higher levels, and at locations where the concentration of radiation is strongest. They have significantly more health and damage than the average feral ghoul. This variant, on death and while attacking, gives off a small amount of radiation. Its secondary attack is when it stretches its arms to the sky and then gives off a burst of radiation.

Glowing trooper ghoul
Glowing trooper ghouls are NCR troopers that have turned into glowing ones, affected by the local radiation levels after the Legion's assault on Camp Searchlight. As with regular glowing ones, they have the ability to emit harmful radiation waves. Removing the head of a glowing trooper ghoul will cause red blood to erupt from their neck, unlike the other limbs on their bodies where the blood glows green.

Overseer
The overseer is a unique orange-colored reaver, encountered in Vault 34's overseer office. It has the same glow effect and radiation blast as a glowing one, albeit a different color. The overseer stands on a raised platform in the overseer's office, on the bottom of which are two Vault-Tec turrets.

Vault dweller
Vault dwellers are a variant of feral ghouls found exclusively inside Vault 34. They are the remains of the population of the vault following the reactor leak. They are completely feral and will attack any human on sight, though they sometimes utter human phrases.

Vault security guard
They are the remains of the Vault 34 security team and are clad in the tattered remains of Vault 34 security armor. They were members of the security team before and during the population control riots. After the reactor leak, they became feral ghouls along with the majority of the vault's remaining population.

Vault security officer
Like the vault security guard, they are the remains of the Vault 34 security team. However, they have become glowing ones that are stronger. While in combat, they may produce a pulse of radioactive energy.

Vault technician
Vault technicians are former technicians in Vault 34, who have since become ghouls due to the radiation leaks. They share a model with the standard glowing one, along with the same strengths and weaknesses. They are found dead in flooded chambers inside of the main section of the vault, in both cases under desks. Also in both cases, the Courier must retrieve two passwords (security and utility) from their corpse to progress further into the vault.

Three are found alive in the flooded reactor level accessed under the desk of the Vault 34 overseer. One wanders the halls, while the rest wait, only breaking through a window and attacking the player character when they are actually inside the reactor itself.

Appearances
Feral ghouls appear

Bugs

 * When the Overseer is killed with an energy weapon, the ash pile remains may not appear. This can be problematic as the quest Hard Luck Blues requires the password found in his inventory.
 * Sometimes the Overseer doesn't attack the Courier, not even when his turrets are destroyed, which is accentuated by the fact he cannot move from his podium/desk.
 * Sometimes there may be a 0% hit chance in V.A.T.S. on their heads, even when the Courier has perfect sight on the head and is close to the target.
