The Appalachia Super Mutants were created shortly before the Great War, when West Tek contaminated the river water that ran through Huntersville with a strain of FEV as part of an experiment.
The super mutants of Huntersville are similar to those of Mariposa and the Institute: they have green skin, highly developed musculature, and they are smart enough to build improvised armor from waste or scrap. Although they do not use large fortifications like the Vault 87 or the Institute strain super mutants, they can occasionally build small fortresses or take entire buildings. Like Vault 87 and Institute super mutants, Huntersville super mutants can grow into behemoths, which can be seen guarding their main bases.
The majority of the super mutants will attack the player character, but some super mutants like Grahm are friendly and will even trade with humans.
Huntersville super mutants have green skin, hyper-developed musculature and are a slightly larger size than humans. Due to the nature of FEV and its origins as the Pan-Immunity Virion Project, super mutants should be completely immune to the Scorched Plague. However, behemoths are still able to become infected.
They possess great strength, which allows them to inflict serious damage with melee weapons, but strong protection can limit the damage done.
Super mutants are carnivorous and hunt all kinds of creatures and animals, including humans, Scorched and large predators, to devour them or stock their meat to build up reserves. Many bags of meat are strewn about in the fortifications of super mutants or carried in their inventory.
The Huntersville super mutants live mostly in small, well-organized groups, often led by a much stronger super mutant.
They often build armor made from scrap iron or rubbish that can provide some protection against the player character's attacks. These armors include the same ones from Fallout 4 and some new ones the most common of which is a mask fashioned from a propane tank. They attack their opponents most often with rudimentary firearms like pipe pistols or more advanced weapons like rifles, shotguns or even missile launchers. Many super mutants fight with melee weapons or use explosives to attack from a distance.
It's rare to see a super mutant escape during a fight because they are not afraid to attack big predators. This includes deathclaws, mega sloths or Scorchbeasts, and will continue to fight even if they are injured.
A super mutant that will run at its enemy with a beeping mini-nuke in its arm. It will then detonate itself while nearby, killing its enemy and itself in a fiery, nuclear explosion. Shooting the mini-nuke in the suicider's hand or targeting the right arm in V.A.T.S. will cause the mutant to explode prematurely, killing it instantly. As a result, shooting the bomb from afar is one of the most effective ways to dispatch them, and potentially other nearby enemies as well. If one is desperate to kill a suicider and the only weapon types available are unarmed and/or melee, the player may either sneak attack it, or run-up to it, strike it, step back a bit, and repeat until it's dead (though the latter is not advised as one missed attack will allow the suicider to detonate the mini-nuke, and accidentally hitting the mini-nuke with either type of attack will detonate it). The suicider can be detected before it is seen by listening for the beeping of its mini-nuke. If the suicider is killed without detonating the payload, which can be done with a headshot or body shot, a mini nuke can be looted from its corpse; otherwise, only nuclear material will be found on its remains.
One of the tougher super mutant variants. Overlords are armed with ballistic weaponry ranging from Pipe guns to miniguns, usually fully automatic. For melee attacks they tend to use anything from boards to super sledges.
The second strongest variant of the super mutants, Primus' are armed with anything ranging from fully automatic pipe weapons to miniguns, possibly a scoped laser rifle. For melee, they use anything from boards up to super sledges.
A super mutant behemoth that was caught in a nuclear Blast zone and irradiated beyond the Forced Evolutionary Virus's inherent radiation immunity. It can also spawn southeast of the vantage in the middle of a lake.
