SCP-939

Description
SCP-939 are endothermic, pack-based predators which display atrophy of various systems similar to troglobitic organisms. The skins of SCP-939 are highly permeable to moisture and translucent red, owing to a compound chemically similar to haemoglobin. SCP-939 average 2.2 meters tall standing upright and weigh an average of 250 kg. Each of their four limbs end in three-fingered claws with a fourth, opposable digit. The jaws of SCP-939 are lined with red, faintly luminescent fang-like teeth, similar to those belonging to specimens of the genus Chauliodus, up to 6 cm in length, and encircled by heat-sensitive pit organs. Eye spots, sensitive to light and dark, run the length of their spined dorsal ridges. These spines may be up to 16 cm long and are believed to be sensitive to changes in air pressure and flow.

SCP-939's primary method of luring prey is the imitation of human speech in the voices of prior victims, though imitation of other species and active nocturnal hunts have been documented. SCP-939 vocalizations often imply significant distress. Prey is usually killed with a single bite to the cranium or neck.

In-Game
In game, SCP-939 is portrayed as SCP-939-89 or SCP-939 Instance 89. It is located in the delivery sector inside Research Facility Site 19. According to the lore, SCP-939 was being transported in a cargo crate, but the Chaos Insurgency and Class-D raid caused it to escape. In Operation Red Skies ε-11 operatives will experience SCP-939 walking around the delivery sector. SCP-939 can be avoided by walking silently/crouching and not standing in it's line of sight. Gunshots will attract SCP-939, yet the best way to avoid it (in case of it chasing a player) is shooting a light. SCP-939 can take damage, but it has a very high health level. In total, there are two SCP-939-89 instances spawning in the delivery sector, each separated from each other.

Prevention
Because of its characteristics, SCP-939 is not able to see you, no matter where you are and the light level you're under. This advises sneaking, as aforementioned. It is also advisable to close the door behind you once you reach the storage, after which you are free to run around however you want.
