**SCP-939** is a keter class SCP in SCP: Containment Breach Unity Edition. It was added in Version 0.5.6 and removed in version 0.6.0.

## 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 hemoglobin. **SCP-939** average 2.2 meters tall standing upright and weigh an average of 250 kg, though weight is highly variable. Each of their four limbs end in three-fingered claws with a fourth, opposable digit, and are covered in setae which considerably augment climbing ability. Their heads are elongated, devoid of even vestigial eyes or eye sockets, and contain no brain casing. 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** do not possess many vital organ systems; central and peripheral nervous systems, circulatory system, and digestive tract are all absent. **SCP-939**'s respiratory system is atrophied and serves no apparent purpose beyond spreading AMN-C227. **SCP-939** have no apparent physiological need to feed, nor any way to digest consumed tissue. Ingested material typically accumulates in the respiratory system of **SCP-939** and is regurgitated once the amount is sufficient to markedly inhibit its function. Despite the absence of many vital organ systems, **SCP-939** are capable of bearing live young.

**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; whether **SCP-939** understand their vocalizations or are repeating previously heard phrases is the subject of ongoing study. How **SCP-939** acquire voices is not currently understood; specimens have been documented imitating victims despite never hearing the victim speak. Analysis of **SCP-939** vocalizations cannot distinguish between **SCP-939** and samples of known victims' voices. The use of biometric voice-recognition security or identification systems at any installation housing **SCP-939** is strongly discouraged for this reason. Prey is usually killed with a single bite to the cranium or neck; bite forces have been measured in excess of 35 MPa.

**SCP-939** exhale minute traces of an aerosolized Class C amnestic, designated AMN-C227. AMN-C227 causes temporary anterograde amnesia, inhibiting memory formation for the duration of exposure, plus an average of thirty (30) minutes. It is colorless, odorless, and tasteless with an estimated ECt50 for inhalation of 0.0015mg•min/m3. In well-ventilated or open air environments, risk of exposure to ECt50 is greatly reduced but *not* negligible. AMN-C227 is typically undetectable in the bloodstream sixty (60) minutes following cessation of exposure. Reported sensations of disorientation and mild hallucinations immediately following removal from environments saturated with the agent are similar to recreational use of numerous psychoactive substances and easily mistaken as such.

## In-game

**SCP-939** is found in the storage area below the rest of the facility. It will spawn here only once the auxiliary ventilation has been activated. After this, it will patrol the area until it detects the player, be it through the sound of their foot-steps or through proximity. Upon detecting the player, **SCP-939** will begin to rapidly pursue the player. Upon reaching the player, it will rapidly attack four times, and getting hit by every attack deals enough damage to kill the player. If the player is on the catwalk above the storage area, **SCP-939** cannot reach the player, though it may attempt to do so. However, it is recommended to remain undetected on the catwalk as the player's exit is on the ground floor.

## Trivia

* **SCP-939** does not currently have a containment chamber, however it will later receive one in the Super Heavy Containment Zone, where more instances of **SCP-939** will be encountered.
* In the future, **SCP-939** will be able to imitate human speech to lure the player if they are unaware.
* The design for **SCP-939** in the Unity remake is very different from the version seen in the original game. Unlike the original counterpart, the remake counterpart is Lankier and more lithe, and has an erect posture as opposed to a sprawled one. It also has differentiated teeth, possessing retractile needle-like teeth accompanied by incisors.
