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 Areas
In SCP:SL there are 4 areas. The Light Containment Zone (LCZ), the Heavy Containment Zone (HCZ), the Entrance Zone (EZ), and the Surface Zone
Areas – LCZ
Light Containment Zone
Alternative name: LCZ
Classes spawning in LCZ: Scientists, Class D Personnel, SCP-173
The Light Containment Zone is the deepest part of the facility. It contains 4 SCP containment chambers, and a few other special rooms which will be listed down below
Each room in LCZ has a codename, which is displayed above the door which leads to the room described. Some codenames are also accompanied by a number, but they don’t mean anything (Unless it’s a containment chamber. In this case the number represents the SCP object (with the exception of PT))
The codenames are explained down below:
HS: Hallway (straight)
HC: Hallway (corner)
IT: Intersection (t-shape)
IX: Intersection (x-shape)
PC: Computer room
GR: Glass room
CD: Class D Personnel Cells
#914: SCP-914 containment chamber
#012: SCP-012 containment chamber
PT: SCP-173 containment chamber
EX-A: Exit leading to the elevator system A
EX-B: Exit leading to the elevator system B
Rooms of interest
Some rooms in the LCZ are more important than others, since they can contain items that can aid you in your escape. These rooms will be listed down below.
The computer room is pretty self-explanatory. It contains computers and that’s it
It always contains a Scientist Keycard.
This room has a chance to contain a Janitor Keycard or sometimes even a pistol.
SCP-372’s containment chamber. SCP-372 is not in SCP:SL, however.
This room can contain a lot of things. Inside the glass chamber there can be a pistol. Inside the locker to the right of the entrance a First Aid Kit, a Scientist Keycard, a Research Supervisor Keycard, or a Zone Manager Keycard can spawn there. Sometimes even a flashlight.
SCP-012’s Containment Chamber
This room contains (or contained) SCP-012. SCP-012 is also not present in SCP:SL. A Research Supervisor Keycard always spawns there. A pistol also has a chance to spawn.
SCP-914’s Containment Chamber
This room contains SCP-914, an SCP crucial to getting good equipment. For more information, see the SCP-914 section.
SCP-173’s Containment Chamber
SCP-173 spawns in this room. Alongside the containment chamber there is a control room, in which a pistol can spawn.
Once you have a keycard with Light Weaponry Access, you can enter this room. It contains various weapons, two workstations (See Weapons section), ammo, weapon manager tablets and grenade containers.
Upon the start of the game, an LCZ Decontamination Process starts. After 15 minutes have passed, all doors in LCS including checkpoint doors and elevator systems are locked, and everywhere inside LCZ a deadly gas starts spreading and killing every living object inside LCZ.
Areas – HCZ
Heavy Containment Zone
Alternative name: HCZ
Classes spawning in HCZ: SCP-049, SCP-079, SCP-096, SCP-106, SCP-939
HCZ is the middle part of the facility. It contains most of the game’s SCP objects. Unlike in LCZ, rooms in HCZ do not have codenames.
Rooms of interest
Elevator Systems A & B
The entrance to LCZ.
SCP-049 Containment Chamber
The elevator in the picture goes to SCP-049’s containment chamber, in which he spawns. Next to the containment chamber there is an armory for which you need a keycard with Heavy Weaponry access. This armory contains a P90, or an M4 and a workstation.
SCP-096 Containment Chamber
Very useful room if you have a keycard with Euclid-Class CC access. An MTF Commander/Lieutenant keycard always spawns there.
Micro H.I.D. Room
Requires MicroHID access keycard to open. Contains the Micro H.I.D. a weapon, which basically melts SCPs.
A two-floor server room. Behind the servers in the top floor in this picture you can always find an MTF Cadet keycard.
There are plenty of such rooms in HCZ. Upon approaching the tesla gate, the tesla charges and bursts after a very short period of time. You need to time your pass correctly to survive.
Doing this with SCP-096 is especially hard due to his slow speed and will probably get you killed if you’re unexperienced.
Alpha Warhead Elevator
Elevator leading to the Alpha Warhead Maintenance Station. In that station you can arm the warhead. You can also find plenty of loot here. In the shelves inside the station there will be most likely a Guard Keycard. You can also find an M4 and a pistol inside the armory along with a workstation.
The main armory of HCZ. Requires a keycard with Light Weaponry access to open. This armory contains a lot of 5.54mm ammo and a workstation.
SCP-106 Maintenance Room
Room, in which you can sacrifice someone to contain SCP-106. For further information, see Classes – SCP-106.
When all 5 generators are active (see SCP-079), the Overcharge process starts. After a minute, the whole facility goes through a short blackout. After the blackout, SCP-079 is recontained.
Areas – EZ
Alternative names: EZ, Entrance
Classes spawning inside EZ: Facility Guard
The Entrance Zone is the last part of the facility. It leads to both Gate A and Gate B: gates, which you need to cross to get out of the facility.
Rooms of interest
The most famous room in SCP:SL. You can broadcast anything you want in here from normal info to USSR Anthem (Earrape Version) 10 hours.
Self-explanatory. In the lockers you can find various keycards, ranging from Research Supervisor all the way to MTF Commander.
Facility Exit. C.I. units will most likely come through this gate into the facility.
Facility Exit. MTF units will most likely come through this gate into the facility.
Areas – Surface
Alternative name: Surface
Classes spawning inside Surface Zone: MTF units (all ranks), C.I. agents
The name is pretty self-explanatory. The surface zone leads to elevators to Gate B & A, facility entrances.
Rooms of interest
Alpha Warhead Control Room
The room used to activate the Alpha Warhead. Requires a keycard with Warhead access to open.
The main objective of D-Class and Scientists. For further info, check Classes – D-Class, Classes – Scientist.
Alpha Warhead Detonation
Upon activating the warhead from the control room, if the warhead was armed first, an emergency evacuation protocol will start throughout the whole facility. During this protocol all doors are permamently opened. After 90 seconds, the underground part of the facility (including gate b & a elevators) explodes, eliminating all life be it mechanical or organical that was in there.
The Alpha Warhead can be deactivated by going into the maintenance station, flipping the lever and clicking the button.
