SCP-939 is one of the seven playable SCP classes in SCP: Secret Laboratory. SCP-939 is effective at picking off single targets with ease, and is capable of misleading players by mimicking its victims. Currently, SCP-939 has the highest chances of spawning out of any SCP, basically being guaranteed. This is simply for the sake of the beta.


Operational Guides[edit]

Class Operational Guide[edit]

The sound of laughter and idle chatter echoes through the hallways. An eerie silence follows. Your instincts scream at you to turn away, to ignore the familiar voices, to run in the opposite direction. 

A sense of unease comes over you as the voices fade into the distance.

But mankind has been known for their limitless curiosity... and the consequences that follow.

___
“They’re terrifying. Sometimes I stay up at night, asking myself if I made the right choice. Questioning my decision to listen to my instincts and to abandon them. Constantly wondering if the voices I heard were genuine chatter amongst the staff or just another imitation from that damn thing. I can still hear the cries, the shrieks of terror that followed in the distance. I didn’t know; no one did. It wasn’t my fault! How was I supposed to know? You would have done the same thing!”
-Dr. Jonathan Essex, Senior Researcher, Site-02

Abilities Operational Guides[edit]


- [M1] — Claw

Press the Attack button and SCP-939 will swing her arm in a wide arc, damaging any players in close proximity. Claw has armor penetration, meaning armored targets will take less damage compared to those who are unprotected. 

___
“Claws as sharp as a sword, teeth longer than daggers. How is it that a human can be turned from harmless to a predator capable of mindless slaughter? This world can be truly terrifying.”

- [C] — Focus

By holding Ctrl, SCP-939 adopts a low-to-the ground pose, allowing them to greatly increase their perception of their surroundings. While focusing, SCP-939 gains the following benefits:

* A new ability: ‘Lunge’.
* The range of ‘Ultrasensitive’ is greatly increased over several seconds.
* Humans visible under the effects of ‘Ultrasensitive’ are recoloured to their class color, e.g.: Class-D will be perceived as orange. 
* Players under the effects of SCP-268 will become visible.

Focus has several drawbacks. SCP-939 can only partially rotate its head and cannot move for several seconds after Focus is deactivated. 

___
“Behavioral studies of SCP-939 instances have shown the object to be capable of limitless patience during a hunt.”

- [Passive] — Ultrasensitive

SCP-939’s eyesight is extremely limited, but they are extremely sensitive to sound. SCP-939 can see the world normally at an extremely short distance. Outside of this area, humans cannot be seen by eyesight. They can only be detected and tracked through SCP-939’s perception of sound. If anyone triggers this sense, a particle will appear at the trigger’s location. Each sound has an individual audible range, with generated particles becoming more faint as they reach the maximum distance. 

Differing sounds have various ranges. For example, a gunshot can be heard from many rooms away while walking cannot be heard from very far.

___
“We’ve finally found a weakness we can easily exploit with this creature. A weapon, originally designed to blind humans, the ‘flashbang’, has been shown to be even more effective against SCP-939. I imagine that our task force teams will be grateful for this discovery if she ever got out.”

- [F] — Amnestic Cloud

SCP-939 can hold or press the F key to unleash a cloud of invisible amnestic gas (holding the key increases the radius). This gas causes human players to lose their perception of SCP-939 and will no longer be able to see it. Humans will be blind to SCP-939’s whereabouts unless:

* SCP-939 attacks them in any way (all players under the effect). 
* SCP-939 physically touches them (individual).
* SCP-939 is shot by a human (individual).
* A human leaves the cloud’s radius for several seconds (individual).

Players under the effect of Amnesia also cannot reload or heal (but may use keycards).

___
“When I was first assigned to SCP-939, there was a gas leak in the extraction pipe for its amnestic gas. The terror I felt was unimaginable. I lost where I was, I couldn't act, and, worst of all… I had no idea where she’d gone..”

- [Shift] — Sprint

SCP-939 is able to sprint extremely fast for a short duration, allowing them to cover great distances and catch their prey. However, SCP-939 may only sprint for a short time, as indicated by a stamina bar. For every second SCP-939 was sprinting, their Ultrasensitive range will be reduced. 

___
“I was assigned to monitor security cameras during SCP-939’s first breach attempt at Site-02. I remember, in vivid detail, watching the researchers desperately attempt to run away. Not one of them made it to the hallway before it had caught them. All of them having their cranium forcibly destroyed. The screaming still haunts me.”

- [C+ Space or LMB] — Lunge

SCP-939 can pounce on their prey, ambushing and killing them. To initiate a lunge, SCP-939 must focus for a short duration. The ferocity of a lunge will kill any player it hits. Additionally, humans near the impact point will take considerable damage.
SCP-939 takes several seconds to recover from a lunge. 

___
“The subject’s anomalous nature and method of reproduction does not distinguish it from other carnivores. The fact remains… She is the hunter and you are her prey.”

- [MMB or V] — With many voices

Activate With many voices to allow the player to speak through their microphone.

SCP-939 may also press MMB to open a radial dial that presents the player with several mimicry options. These options allow the player to trick humans into believing a particular situation is occurring. Each sound effect has its own cooldown. 

___
"In Ancient Aethiopia there was an animal they called the Crocottas or "dog-wolf". It is said to mimic the human voice; calling their prey and devouring them. It was faster and stronger than anything commonly known today. I wonder... Has this object really been around for that long?"

In Game[edit]

At the start of the round, SCP-939 will spawn in its Containment Cell located in Heavy Containment Zone. SCP-939 acts as an ambush class for the SCPs, having many abilities useful for tracking humans down and taking them by surprise.
SCP-939 can talk to the other SCPs by holding down the Q key. This voice chat can be heard by all SCPs, regardless of distance.

Hume Shield[edit]

  • SCP-939 has a base Hume Shield value of 350.
    • At 20% HP, SCP-939 will have 700 Hume Shield.
  • If SCP-939 takes no damage for 20 seconds, her Hume Shield will regenerate at 25 HS/s.

Abilities[edit]

Claw[edit]

SCP-939 can perform a Swipe AoE attack with Left Click.png Left Click, with a range of roughly 1.1 meters. The player can hold down Left Click.png Left Click to automatically repeat the attack. Each swing takes roughly 0.6s to complete. The attack itself deals 30 damage and has 75% penetration. While the attack damage is lower than SCP-049-2's swing attack, the 0.6s attack speed makes it have a much higher DPS, allowing it to kill a player much faster than SCP-049-2.

The following chart displays detailed information over SCP-939's Claw ability with damage modifies, these assume no healing items are used and the player being attacked is at full health (100):

  • The AHP section is based on a player with 75 AHP and does not factor in decay.

Ultrasensitive[edit]

SCP-939 has extremely weak eyesight, making it difficult to see players in game. While her eyesight is weak, SCP-939 is extremely sensitive to sound, allowing SCP-939 to see audio sources from far away. Audio sources within a range of SCP-939's hearing will appear as a blip on the player's screen, with different ranges based on the source.

SCP-939 can visibly see all players within their small "eyesight" radius. The possible ranges are the following:

  • Default: 1.5 meters
  • Stamina (Max Penalty): 0.75 meters


The distance SCP-939 can see "sound blips" are directly based on the volume of said sound. They are roughly the following:

  • Footsteps (Walking), Reloading, Using Medical Items, Consuming SCP-207 or SCP-500, Applying SCP-1853
    • Default: 15 meters
    • Stamina (Max Penalty): 7.5 meters


  • Footsteps (Sprinting/Jumping), Grenade Beeping, Elevator
    • Default: 18 meters
    • Stamina (Max Penalty): 9 meters


  • Doors/Gates, Glass Breaking, Using the Micro H.I.D.
    • Default: 30 meters
    • Stamina (Max Penalty): 15 meters

SCP-939 can see players who are currently using their mic, this distance is based on how loud the player is talking into their mic.
The player's speed affects the distance SCP-939 can hear their footsteps, caution should be taken with items that increase speed.
The Deafen Makes all noises muffled and quiet for a short time Status Effect will prevent SCP-939 from seeing sound triggers for the duration of the effect. Making Flashbang Grenades an effective tool to counter SCP-939.

Focus[edit]

By holding C, SCP-939 will begin to crouch low near the ground over two seconds. During these two seconds, SCP-939's FOV will slowly widen to 20 degrees while their speed will drop by 10% every 0.2 seconds, up to 100%. After the two-second preparation time, SCP-939 will be given increases to her perception, plus the ability to Lunge forward.

The following benefits are also applied while Focused:

  • Certain sound trigger blips will now be recolored to match the class that made them
    • Footsteps
    • Micro H.I.D.
    • Unsilenced gunfire
    • Medical Items being used
    • Reloading
  • If the player leaves Focus, all of these benefits are instantly revoked.


The ability can be canceled at any time by releasing C, with the time returning to standing up being based on how long the player held the key, up to two seconds.

Amnestic Cloud[edit]

While in a valid location, SCP-939 can release an Amnestic Cloud into the area by holding the F key for two seconds. The radius of the cloud is determined by how long the player held the key, up to a max charge time of eight seconds. Humans inside the cloud receive the Amnesia Inability to reload and use medical items. SCP-939 becomes invisible to players under this effect. Status Effect. The effect last the entire duration the player stays inside the cloud plus roughly two seconds after leaving. While players under the Amnesia effect are unable to see SCP-939, touching or hurting her will cause all players to see SCP-939. All players will briefly see SCP-939 if they perform an attack, such as Claw or Lunge. SCP-939 being invisible to players under Amnesia makes it easy for her to attack targets by surprise or retreat without being detected. Though, players with the effect can't hear any Mimicry used by SCP-939.
The cooldown of the ability is 3x the charge time. So, charging the ability for five seconds, will give a 15 second cooldown.

The Invigorated Gives the player infinite sprint Status Effect that is applied from Adrenaline will counteract and negates the effects of Amnesia for duration of the effect.

A valid location is any spot that is the same elevation as any door in the facility, regardless if it is flat or not. There are some exceptions to this rule, such as the very bottom level of SCP-079's containment chamber and the flat areas of the Surface Zone's Escape Area.

Lunge[edit]

While Focused, SCP-939 can Lunge forward at 10.8 m/s by pressing Left Click.png Left Click. While in air, the direction of Lunge can be altered up to 40 degrees, after hitting this capacity it can no longer be altered. Lunge will deal 120 damage to any unfortunate player that SCP-939 lands on. If multiple players are nearby each other, only one of them will take 120 damage, the rest will only take 30. It takes about two seconds for SCP-939 to recover from a Lunge, giving players a short time to attack.

Sprint[edit]

Similar to Humans, SCP-939 can sprint at 7.2 m/s by holding Shift. Her Stamina is not very high, and will be fully depleted after ten seconds. Their Stamina bar has a ten second delay before it begins to regen at a rate of 10% per second. This regen delay is ignored if the player only held the key for 0.3s or less.

While not sprinting, SCP-939's footsteps are silent.

Mimicry[edit]

Mimicry is an ability that allow SCP-939 to mimic other noises to confuse other players. By holding the Tab key, a special menu opens up for the Mimicry ability. The menu contains four options, three are different types of mimicry while the fourth is a "set mimic point". The "set mimic point" will place a marker where SCP-939 is currently looking at, up to a max distance of 7.5 meters. This marker can only be seen by SCP-939 and will go away if SCP-939 travels more than 20 meters away from it or places down a second marker.

Stealing A Voice[edit]

One of the options in the Mimicry ability menu, when selected, SCP-939 will play the last four seconds of speech of a recent human they killed. The ability has a cooldown of ten seconds, and will be broadcasted at a Mimic Point if one is placed. An option exist to play the audio client side only, as well as an option to delete a recording. A total of eight voices can be stolen at a time, any additional ones will delete the oldest recording.

Players have the option to prevent SCP-939 recording their voice in the game's settings, and was added for legal reasons.

Recordings are automatically deleted if human player leaves the server in any way.

Footstep Mimicry[edit]

Trivia[edit]

  • Interestingly, SCP-939 sees via sound in-game, despite the SCP-939 wiki article suggesting SCP-939 uses heat and air pressure to see their surroundings.
  • Before SCP-939's rework in the Mimicry update, there were two variants of SCP-939, known as SCP-939-53 and SCP-939-89. Both had different models, but worked exactly the same. It was possible for both SCP-939s to spawn in a round.
    • It was originally planned for there to be one SCP-939 model, but due to a miscommunication, two models were made. It was decided to add both in-game, and have the possibility that two SCP-939s could spawn.
  • SCP-939 will sometimes flinch and scream when taking damage. The following will trigger this reaction:
    • Hume Shield bar is lowered to zero.
    • Taking damage while at full Hume Shield.
    • SCP-939 receives 90 damage in a short period of time, requiring a DPS of roughly 81 to meet the requirements (There is a 10 second cooldown between each flinch)
