Feral ghouls (Fallout 76)

 are creatures found in Fallout 76.

Characteristics
 These long gone, decaying sacks of flesh run the gamut, from being little more than a nuisance to a hardy and stalwart opponent. Once disturbed, they growl and scream to alert other ghouls in the vicinity, causing them to attack in packs, viciously rushing and pursuing whomever or whatever disturbs them.

The most important feature is that feral ghouls will reflexively duck and dodge incoming fire while closing distance, making automatic weapons or explosives a preferred method of dealing with them. Furthermore, ferals will not be stopped if they lose a limb or two. If they lose their arms, they just keep on coming to slam their bodies into and bash their skulls against the attacker. The only way to kill them is to deplete their hit points, but they can be neutralized by blowing off both their legs. Well-placed explosives and especially mines are very good at quickly shaving off surplus limbs.

Feral ghouls have the ability to climb low fences and drop down from height if it means they can get to their prey.

Of note is the fact that most lower-level ghouls (everything below withered) have been equipped with a new spawning system that gives them varying appearance (different clothes and headgear) to match the variety of environments they're encountered in.
