Changelog - 8.0.0 - Megapatch Part I

Version 8.0.0

After a long wait, we are glad to announce part 1 of the Megapatch is ready to be launched! The patch will be released within 24 hours since now! (we're targeting 10:00-12:00am PST). The final release date will be announced on our Discord server (
Find out what’s heading your way below.

  • Return of SCP-079

    SCP-079 is back with some new abilities and toys to play with!
    Please note, that SCP-079's development isn't finished yet . We have to collect feedback to make a solid plan of the further development.
    • Movement - 079 can now use 3 modes to move around, which are:
      • Map - activated with tab, allows 079 to click on rooms and move there
      • WASD - changes with your camera rotation, for example, W will move you to the camera in front of you
      • Clicking cameras - the old way of doing things, 079 can just click the camera icons to move to his next location
    • 079’s HUD - completely reworked, including more necessary information
    • Ability usage - SCP-079 now uses a power called “Auxiliary Power” that recharges over time, it works like mana, that can be used to activate 079's abilities
    • Experience - can be earned by performing actions or simply assisting human kills. Leveling up increases the AP regeneration and unlocks new abilities.
    • Camera movement modes - There are 2 ways of rotating (looking around) your cameras, switchable using spacebar.
    • Tesla gates - SCP-079 can now use tesla gates to his advantage, by using a single instant burst instead of a massive overcharge; practically, we've found it much more efficient than the previous one
    • Locking doors - now instead of a constant time, the door will be indefinitely locked with a constant power decay until 079 presses right-click or runs out of Aux Power.
    • New ability - 079 can now shut down all the power in a room, turning off the lights and locking the doors.
    • Zone-specific camera models, that actually rotate, and tell you if SCP-079 is looking at you.
    • Elevators - 079 can send an elevator up/down to disadvantage his enemies.
    • New recontainment system - There are five generators placed all around the HCZ. These will power up 079 each time they are turned on. However, if all are turned on, a mini-event will occur, where 079 begins to be "fried" out of the facility hardware, gaining a lot of power temporarily before dying. These generators require Weapon Manager Tablets to operate.


  • Weapon System Changes

    • New weapon: USP
      A new "tool" for those pesky Class D's!
      We've added a USP gun, that can hold a couple more attachments than the previous pistol!
      Beware though, only one will spawn and hold its true glory.

    • Weapon attachment changes

      Get ready with those tablets, weapon attachments are now persistent.
      What does this mean?, you may be thinking.

      Any weapons dropped by fellow players will retain the attachments that player had set on them.
      Fancy an E-11 with a scope, while wanting a Red Dot sight for CQC? Now you can! (Just be sure to pick, or modify the carefully 'obtained' second rifle!)
      You now need to hold the weapon you wish to modify.

    • General improvements
      We’ve also balanced the attachments, improved holo sight effects, and E-11 SR shaders.

  • General changes

    • C.A.S.S.I.E. - announces more detailed information about SCP deaths, telling what killed it specifically (i.e. kill by a Tesla Gate, Warhead detonation, etc).
    • Major Scientist keycard can open checkpoints now!
    • Respawn system - has had a few tweaks and changes to improve the queue and way it decides who will spawn in each wave. Spectators chances to respawn increase with the awaiting time.
    • New Permission Manager - allows you to control and set in-game roles via RA. (Use with command PM)
    • Broadcast/bc command - allows you to send a message to all players through the Remote Admin!
    • Hiding UI - You can now hide the UI! Do so by pressing “P”.
    • Engine, Steam & Voice Chat Update - General updates to our systems have been made, and stability of the voice chat has been improved.

  • Bugfixes

    Thanks to your feedbacks, here are the bugs that got fixed in this release:
    • -1HP/One shot bug on self-hosted servers fixed
    • Fall damage in 106 room when exiting the Pocket Dimention fixed
    • Playerlist was sometimes shown empty. Fixed
    • Fall damage when gliding against a surface fixed
    • Fall damage in elevators when jumping fixed
    • MicroHID locking the inventory fixed
    • Standing on a locker's door in the Entrance zone won't trigger the anti-cheat anymore
    • The janitor card can now be given through the Give Item command

    If you notice a bug that wasn't reported, feel free to let us know on the Steam forum.

About This Game

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.
