Gulper

Gulpers are mutated creatures found in Appalachia and the Island.

Biology
Salamanders native to Maine that found themselves drastically altered by both the nuclear fallout of the Great War as well as the persistent radiation of the Fog. These creatures have grown exponentially, easily towering over most humans. One of the rare creatures found on the islands of Maine, the gulpers are analogous to deathclaws. Like their reptilian cousins, they keep the natives constantly in fear, as they are shown as having no issue with assaulting the local homesteads and towns. They share their special attacks and animation set with the deathclaws.

Gulpers are mutated salamander-like creatures that roam the Island. They can hang on trees in order to take their victims by surprise. They can also slide through swamp-like areas and hide underwater. They tend to stay near bodies of water, as said by Old Longfellow, and can grow to the size of deathclaws.

Gulpers are descendants of pre-War salamanders. Preferring to stay near water, they can also hang on trees in order to take their victims by surprise, slide through swamp-like areas, and hide underwater. Gulpers can be found throughout the Mire and the Cranberry Bog.

Their skin is coated in a thin mucus, and their coloration is blotchy and uneven. They stand with a hunched back around six feet tall and walk upright on their hind legs when moving slowly or standing still. They run using all four legs and are able to outrun a non-mutated human. If a player gets too close, they can pounce and swing their massive clawed hands, dealing significant damage.

Having movement patterns similar to deathclaws, when engaged in combat, they will rush towards the player, trying to dodge bullets if shot, and will attack with its paws and its large mouth, or even do a slide attack where they hit the player with their snout.

Gulpers can also be seen hanging upside down on tree branches, dropping down to attack the player when they come near. Gulpers also have the passive ability of slowly regenerating health. Gulpers will not enter buildings or climb stairs. If a player enters a building or climbs stairs, the gulper will retreat but stay in the general area.
