SCP - Containment Breach Wiki

SCP-106, known as "The Old Man", is a hostile SCP encountered in SCP - Containment Breach.


SCP-106 is an elderly humanoid, with a general appearance of advanced decomposition.

SCP-106 causes a “corrosion” effect in all solid matter it touches, engaging a physical breakdown in materials several seconds after contact.

SCP-106 is capable of passing through solid matter, leaving behind a large patch of its corrosive mucus. SCP-106 is able to “vanish” inside solid matter, entering what is assumed to be a form of “pocket dimension”.


SCP-106 is a mobile threat, and appears quite often. It can spawn at any time near the player (either from the floor or from the ceiling). Once SCP-106 has spotted the player, it will immediately begin to pursue them. SCP-106 is difficult to deter, due to it being able to phase through doors, with the only way to shake it off being to wait out its pursuit for an amount of time or trick it into walking into a Tesla gate, stunning it and causing it to retreat. Should the player wander too far from SCP-106, it will teleport closer to them. If the player attempts to pause the game while being chased by SCP-106, the game will quickly unpause with the message "STOP HIDING".

If SCP-106 manages to catch the player, it will take them to its Pocket Dimension. At the first intersection, SCP-106 will wander around this room in a counter-clockwise pattern through the walls of the hallways. Physical contact with it in this dimension results in instant death. After it performs 3 full rotations around the map it'll head straight towards the player if they are still in the intersection.

SCP-106 appears again in the pillar area. SCP-106 will be floating upside-down a few pillars away and will teleport to adjacent pillars, coming closer to the player. Every time SCP-106 teleports, the player is forced to blink.

In the throne room, SCP-106 will be perched atop a large throne-like column. The player is only able to see its eyes and upon approaching the throne, the camera is forced up in its direction. Staying too long in the room will cause a deep voice (possibly that of SCP-106) to tell the player to kneel.

  • "Kneel."

SCP-106 can also spawn in events, such as in the Maintenance Tunnels, in front of SCP-895, or when it captures a janitor in an end room. It can also be seen traversing across the grated hallway and the T-shaped hallway where it drops a dead scientist from the ceiling.

In the T-shaped hallway or the four-way hallway, the player can occasionally find a large sinkhole in the center of the room. Walking into the center of it will cause the player to sink into it and be teleported to the Pocket Dimension.

SCP-106 appears at the Gate A ending, attempting to escape when it is effectively halted with the H.I.D. Turret, causing it to retreat to its pocket dimension. However, If SCP-106 is contained by the player beforehand, this cutscene will not occur and the player will unlock the alternate Gate A ending.

Judging by the corrosion found in Dr. Maynard's room and the fact that the player can find his security code note in the pocket dimension, it is presumed that Maynard was taken by SCP-106.

Dr. L.'s notes reveal that he was being tormented by SCP-106 and begun to go insane because of it. Entering his office will reveal that the room is completely corroded in moss stone similar to that of the Pocket Dimension.

SCP-106 can be detected using an S-NAV Ultimate, even if the corrosion sound is not heard.

At some point before the game's events, Agent Skinner (whom is actually a Chaos Insurgency operative) allowed SCP-106 to breach containment. This in turn allowed Dr. Maynard to enter SCP-079's containment chamber unnoticed as the site was busy dealing with SCP-106's breach.

Recall Protocol

Upon entering SCP-106's containment chamber, the player has the option to use the Recall Protocol to re-contain SCP-106. The following is a step-by-step process to successfully recapture SCP-106:

  • Obtain an individual between the age of 10-25 (already done, thanks to a pre-restrained lure subject).
  • Turn off the magnets switch (ELO-IID magnetics).
  • Turn on the intercom to transmit the sound throughout the facility.
  • Press the femur breaker button (automated hydraulic press) and wait for SCP-106 to appear.
  • Once SCP-106 appears in the chamber, quickly turn the magnets back on.

This should successfully re-contain SCP-106 and it will no longer appear around the facility. Note, that if the player does not turn on the magnets before the screen blacks out from corrosion, SCP-106 will not be contained, and will chase the player instead. The player can also turn off the magnets once SCP-106 is contained if they want to release it. If the player fails to correctly contain the SCP or lets it out, it is impossible to re-contain it.

Re-containing SCP-106 also allows the player to reach the alternate Gate A ending.

A document about the protocol can be found on a desk next to a keyboard.
