From SCP: Secret Laboratory English Official Wiki


The Heavy Containment Zone is one of four zones found in SCP: Secret Laboratory. It contains the Micro H.I.D. as well as the three Emergency Power Stations.

Description

Heavy Containment Zone (HCZ) is one of four zones in Site-02.
Placed below Light Containment Zone and located right next to Entrance Zone, it is considered one of the most dangerous zones as it is the spawn location for SCP-049, SCP-079, SCP-096, SCP-106, and SCP-939.

Heavy Containment Zone is also the only zone affected by the Overcharge event, which is used to re-contain SCP-079. This event occurs after all 3 Emergency Power Stations have been activated, and the button in SCP-079's Containment Chamber is pushed (this can also occur when SCP-079 is the last SCP alive).

Heavy Containment Zone contains a few important rooms that contain items that can aid a player in escaping or re-containing a SCP.

Unique Areas

Unique areas include containment chambers or other rooms of interest that spawn only once. These areas may include valuable items, weapons or have an important gameplay role.

Elevator Systems

Elevator System A
Elevator System B
Elevators after LCZ is locked down

The Elevator Systems are two rooms that contain two elevators that connect Heavy Containment Zone to Light Containment Zone.

Above each elevator is a timer showing how much time is left until Light Containment Zone gets Decontaminated.

Tesla Gate

The Tesla Gate
ZAP!

Tesla Gates are straight hallways equipped with high powered tesla coils.

If the player enters a room with a tesla gate, it will activate its sensors and charge itself. Standing next to the tesla gate will cause it to fire a large amount of electricity. If a player is in the tesla coil when it is firing, it will shock and deal massive damage, instantly killing humans, SCP-106 and SCP-049-2. Tesla Gates only deal damage for three ticks, allowing most SCPs to not die in one blast.
Tesla Gates are quite loud and can be heard from several rooms away when operational.

If SCP-079 viewing a room containing a tesla gate, the tesla coil will begin to charge itself even if no player is nearby.


Server Room

Top level
Bottom level

The Server Room is a two-level room full of servers. This room is mainly used for hiding.

A Scientist Keycard can spawn either on the top or bottom floor behind the servers.
Up to two First Aid Cabinets or Emergency Power Stations can also spawn on the top floor.

2 common hiding spots in this room include behind any of the servers or in a small area under the stairs.

The Alpha Warhead Silo is the location of the Alpha Warhead. It is located above HCZ, and can only be accessed via an elevator system.

In the center of the area, is the silo itself, with the Alpha Warhead seated in place.
Opposite of the elevator system is a small control room, which contains a control panel. This panel is used to activate or deactivate the warhead.
The control room is covered by a wall with openings that face the elevator system. These openings make great cover when shooting enemies coming up the elevator.

Beside the control panel is an armory which does not require a Keycard to enter.
The armory will always contain a Workstation, and either a MTF-E11-SR Rack or Weapon Locker Type 21 as well.

Two Emergency Power Stations can spawn on the wall in this area.

The entrance of SCP-079's Containment Area is a small stairway which leads to the two gates outside SCP-079's chamber.

At the start of the round, both gates will be locked shut and cannot be opened until all 3 Emergency Power Stations have been activated. Once all 3 have been activated, the gates will be forced open.

Behind the gates is a medium sized room that contains SCP-079 behind a cage.
There is also a side room that contains lots of loot and a button to terminate SCP-079. Pressing the button will cause the Overcharge event to occur, and will allow the gates to be open/closed with any keycard with Containment Tier 2. Near the upper right of the button, one of the four hidden Hubertballs can be found. It is nearly impossible to see without noclip.

A plaque can also be found in SCP-079's room for the ARG event held in December of 2019. The plaque has a list of the main people who participated in the event.
Scanning the QR code on the plaque leads to the following link

The area outside the gates contains two possible spawn locations for Emergency Power Stations.

SCP-106's Containment Area is a massive room that contains the chamber of SCP-106. This room is a even darker compared to the rest of the HCZ.

To the right of the entrance is SCP-106's containment chamber. The chamber floats above the ground, held in place by powerful electromagnets. The chamber can be jumped to from the entrance platform, but missing the jump and falling is fatal. The top of the chamber can act as a hiding place or to avoid some SCPs.

The main doors require a keycard with Containment Access 3  Janitor Icon dark.png Guard Icon dark.png ZManager icon dark.png
Scientist Icon dark.png Cadet icon2 dark.png Owner Icon.png
Research Supervisor Icon dark.png Lieutenant Icon dark.png Chaos card icon2 dark.png

to open. Both doors will lead to the main control area in SCP-106's chamber.
Both doors function on a time lock similar to checkpoints and will automatically close after 10 seconds.

Inside the control room is a shelf, several control panels, a button, and the Femur Breaker.
The Femur Breaker is a small room that allows a single person to sacrifice themselves and re-contain SCP-106. Once a human goes inside the Femur Breaker, they are instantly killed and the door is closed behind them. Another human is also required to push a button in the control room. Once the button is pushed, an audio cue will start to play and soon after, SCP-106 will be re-contained.

An Emergency Power Station can spawn near the entrance of the room.

SCP-106 will spawn at the bottom of his containment chamber at the start of the round.

Trivia

  • In 3-Way Intersections, two doors are noticeably uncentered. Have fun knowing this forever.
  • Since SCP-173 teleports between blinks, it is possible for them to teleport outside the walkway and into the pit at the Ammunition Armory.
