SCP-939

Function | Antagonist

**SCP-939** is a keter class SCP in SCP: Unity. It was added in Version 0.5.6. It was later temporarily removed in Version 0.6.0, and re-implemented in Version 0.6.5.

## 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 Packaging/Logistics Storage in Sublevel 3. If the player enters the storage area adjacent to this room, an **SCP-939** instance will emerge from the vent and begin patrolling the room. **SCP-939** is blind, and will not chase the player by sight; however, it will attack should it hear the player, which it is very capable of doing unless the player is crouching some distance away, or touch the player. Upon detecting the player, **SCP-939** will give chase and attempt to kill the player. **SCP-939** can attack four times in rapid succession, and can kill the player in six hits. **SCP-939** is about the same speed as the player's run, possibly faster, so it is recommended to get a door between you and it, as it will follow through open doors. If locked out of the room it spawned in, it will patrol the area it has access to upon the player's escape. Given the opportunity, however, **SCP-939** will always return to Packaging/Logistics Storage and will not leave again without further prompting.

## 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.
* In Version 0.6.0, **SCP-939** was temporarily removed while the devs prepared a new, upgraded storage room. While as of now this has not happened, a smaller **SCP-939** instance was added in Version 0.6.5.
* In Version 0.8, **SCP-939** will receive an animation update as well as more appearances as the Warehouse returns to the game. It is unknown to what capacity adult **SCP-939** instances will return, but concept art indicates at least 2 will be present patrolling the room.
