About SCP: Secret Laboratory

Deep within the SCP Foundation during a containment breach, many of the anomalies have bypassed security and escaped from their chambers – without peaceful intentions. Become site personnel, a re-containment agent, or an anomalous entity and fight to take control of or escape the facility!

SCP: Secret Laboratory is a multiplayer horror game, based on SCP – Containment Breach by Undertow Games (in 2012). To create this game, Unity engine was used to provide higher stability and more details. Still being in the beta phase, the game can contain a number of bugs and errors which are usually spotted by a large team of testers and fixed quickly after.

It is a completely free horror game based on SCP Foundation creepypasta series. The Foundation focuses on protecting the world from any entity, object or phenomenon which exceeds the all-known idea of normal.

The underground facility suffers from multiple breaches from various SCP objects which escape their containment chambers. During this events chain, players are given roles to play:

  • Class-D Personnel – Prisoners kept for a purpose of being lab rats. Their mission is to escape the facility without getting any attention from others.
  • Nine-Tailed Fox – Team designated to neutralize the danger and rescue Scientists.
  • Scientist – Breach attendant that tries to escape the facility alive.
  • SCP Object – anomaly trying to kill as many people as possible. Currently, only few SCP objects can be found in-game, but progressively their number will grow in oncoming updates.
  • Chaos Insurgency – Foundation traitors, trying to help Class D to escape in order to obtain helpful information.

The randomly generated facility and role division make every game special and full of sensations! You never know where you are heading or what awaits you behind the next door, no matter what role you are playing. The winner team is one that finished all of its objectives.

There are many ways of fighting against enemies, from using firearms to detonating the whole facility with a hydrogen bomb.
In the game, we can encounter such anomalies like:

  • SCP-173 – Living concrete sculpture that can move only when not observed, killing people by snapping opponents’ necks.
  • SCP-106 – Humanoid able to walk past matter, sending its prey to its Pocket Dimension.
  • SCP-049 – Plague doctor trying to “cure” everyone he meets.
  • SCP-914 – Object improving machinery.
  • SCP-096 – “Shy Guy” who screams and goes on a rampage upon looking at him.
  • SCP-939 – A monster, which can only see if you make sound.
  • SCP-079 – Sentient AI, which tries to stay on during the breach.

Version 11.2 brings long-term stability tweaks and two new SCP items

Hello, everyone. Today we’re releasing version 11.2 of SCP: Secret Laboratory! This update introduces two new SCP items, and a plethora of minor additions, tweaks, and fixes.

SCP-1853, ”Performance Enhancer”
Thanks to the inventory rework introduced in Parabellum, it's now much faster to implement new items into the game. With this update, we're introducing another one: SCP-1853.

The Performance Enhancer is a glass vial of sludgy, green liquid. It can be found inside pedestals throughout the facility. When consumed, it heightens the user's physical abilities and reaction speed, especially in combat. This manifests in the form of an increased ability to handle weapons — including fire rate, reloading speed, and so on. It also boosts sprint speed, but at the cost of increased stamina consumption.

SCP-1853 interacts with other SCP items in different ways. Taking it with SCP-207 will poison the user, while SCP-500 will cancel its effects entirely. Taking it with more of itself will stack the effect but with diminishing returns.

The return of SCP-244, "Ice Fog Jar"
During 2021’s Christmas event, we demoed SCP-244; the Ice Fog Jar. From the get-go we planned to keep it as a permanent addition, but quickly found that it was performing below expectations. As a result, we held off on re-implementing the item to give it more time in the pipeline. Finally, we believe we're ready to bring the jar back into the facility.

As a refresher: SCP-244 is a re-usable environmental hazard that can be picked up and placed by human classes. When placed, it will spew icy fog from its mouth which will fill the area around it. Doors will block the fog from spreading to other rooms. In addition to impeding visibility, SCP-244's fog is also freezing cold. This will impart negative effects to any class that passes through it.

Some highlights of what we've changed from the Christmas version include:

  • Fog now spreads much faster and will reach full size more quickly.
  • Humans caught in the ice fog have increased penalties to weapon handling and take much longer to pick up items.
  • SCPs with a Hume Shield will start taking damage to the shield after spending at least 5 seconds inside the fog.
  • Most SCPs will be debuffed in various ways while inside the fog. For instance, SCP-049 takes longer to revive corpses and has an increased attack cooldown.
  • The fog serves as a line-of-sight blocker for the purposes of vision-based SCPs like SCP-096 and SCP-173.

We're hopeful that this version of SCP-244 will be significantly more powerful than its previous iteration, and that it'll affect rounds in a more meaningful way.

Win conditions revamp
One part of SCP: Secret Laboratory that has remained largely unchanged is the win conditions — how the game determined which team was the winner at the end of a round. In addition to being unclear, some reasons were silly. It wasn’t always obvious why a team was determined as a winner. As part of 11.2, we've completely overhauled these conditions.

Up until now, the win conditions have been as follows:

If Foundation forces are the only remaining team: Foundation win if at least one scientist escaped. Otherwise, stalemate.
Otherwise, if at least one Class-D escaped: Class-D win.
Otherwise, if at least one SCP is alive: SCP win.
Otherwise: Stalemate.

These aren't great for a few reasons, but the biggest problem is that it didn't account for how many of each civilian class escaped. It only accounted for if any civilians escaped. This meant that even if all scientists escaped and only one Class-D, the Class-D team would still win. This is, as long as the NTF weren't the last team standing. These conditions produced a lot of strange interactions.

Our new win conditions look like this:

We decided to focus on each team's individual performance instead of looking at certain values in a vacuum. At the end of a round, we compare the following values to determine how each team did:

  • CI/Class-D: Class-D escapes.
  • Foundation: Scientist escapes.
  • SCPs: Remaining SCPs.

Civilian escapes is the main influencer of which team is determined as the victor. For SCPs, we look at how many of them are still alive at the end of the round, as this is generally a good indicator of how successful they were in wiping out other teams.

Several other balance changes went into this revamp. For instance, disarmed civilians that escape no longer count as an escapee for any faction. They'll still respawn as a member of the opposing team but their escape won’t contribute towards win conditions. This allows civilians to be escorted out by hostile forces, but now you have a choice: save your own hide, or take the risk to try and bring your team closer to victory?

If the flowchart isn't clear, here's how the game determines the winning team now:

If Foundation forces are the last remaining team: Foundation victory if escaped scientists outnumbers or equals escaped Class-D. Otherwise, stalemate.
If the SCPs are the last remaining team, or the SCPs and the Chaos Insurgency are the last remaining teams: SCP victory if surviving SCPs outnumber both scientist and Class-D escapes; CI victory if Class-D escapes outnumber both surviving SCPs and scientist escapes. The CI breaks ties.
If Chaos Insurgency forces are the last remaining team: CI victory if escaped Class-Ds outnumbers or equals escaped scientists. Otherwise, stalemate.
Stalemate as a fallback in case no other conditions are met (i.e. all players dead.)

Going forward, we hope that this will result in more sensible victories for all three factions.

Patch notes
SCP: Secret Laboratory — Version 11.2


  • Implemented SCP-1853, "Performance Enhancer".
  • Re-implemented SCP-244, "Ice Fog Jar".
  • The size, shape, and color of reflex sight reticles can now be customized at a workstation. Each attachment preset can have its own configuration, and weapons dropped by other players will retain their choice of reticle.
  • Implemented a new shotgun attachment that fires both rounds at once at the cost of lowering fire rate.
  • Implemented a 30-round AP magazine attachment for the Crossvec.
  • Reintroduced the 3-X Particle Disruptor from the Christmas 2021 event. You'll have to experiment to discover how to obtain this anomalous weapon.
  • Added idle animations and equip sounds to items that were missing them.
  • Added new audio for SCP-173's Tantrum ability.
  • Added new audio for equipping and throwing grenades.
  • Added new audio for the Revolver's inspect animation.


  • Refurbished which team is determined as a winner at the end of the round. As a rule of thumb, it now depends on civilian escapes.
  • Added more pedestal spawn points for SCP items.
  • Pedestals feature a small lamp and a label corresponding with the designation of the SCP item they contain.
  • Throwing an item can be canceled by pressing the reload key. This works with grenades and other throwable objects, like SCP-018 and SCP-2176.
  • Mouse sensitivity while aiming down sights can be adjusted in the in-game settings menu.
  • Aiming down the sights can be done using a toggle. This can be enabled in the in-game settings menu.
  • It's possible to start a reload while aiming down sights with the Revolver and Shotgun. It was previously only possible on automatic weapons.
  • Players no longer collide with any of SCP-079's cameras.
  • Reworked all layouts of the Light Containment Zone.
  • The maximum view distance for the game to consider you as seeing SCP-173 is now doubled on the Surface Zone, to account for the reduced fog.


  • The Alpha Warhead control room on the Surface Zone no longer requires a keycard to access.
  • The reset time of SCP-079's generators is the same as their activation time.
  • Reduced the total range of the Shotgun. (Important note: improvements were made to the Shotgun's hit registration that necessitated this — see the Fixes category.)
  • Slightly increased the damage of the Crossvec and nerfed its base armor penetration.
  • SCP-173's Tantrum can be destroyed by explosions.


  • Fixed an issue with the Shotgun's hit registration not properly accounting for latency. It should be much stronger than before.
  • Fixed the Logicer's ammo belt getting desynchronized with its actual ammo level.
  • Fixed an issue on high-ping servers where you could accidentally teamkill players that weren't visible on the screen.
  • Fixed a visual bug with the Epsilon-11 where muzzle attachments weren't positioned correctly on its hotkey thumbnail.
  • Fixed a long-standing issue where vsync would enable automatically when joining a game.
  • Fixed subtitles overlapping during multiple announcements.
  • Fixed the Alpha Warhead's fog being applied to players with godmode.
  • Fixed the test for the Marauder and Repressor being swapped in Remote Admin's class change submenu.
  • Fixed escaping from the Pocket Dimension into TC-01 allowing you to clip out of the map.
  • Fixed a visual glitch in SCP-939’s starting room.
  • Fixed the Settings tab in the main menu being unusable until switching away from and back to the menu.
  • Fixed the Bloom setting being forced on when joining a game.
  • Fixed being able to use the radio after dropping it from the inventory.
  • Fixed players becoming a target of SCP-096 when they shared a moving elevator with SCP-096 itself.

Although version 11.2 features plenty of content, it's mainly a maintenance update. We aim for this to be the final update in the Parabellum series; barring any hotfixes we need to release for outstanding balance or technical issues, of course. Work is already underway on the foundational work for our next content patch (as we explained in our latest devlog). We're excited to show you what comes next, when the time is right.

See you in the dark.
