SCP: Secret Laboratory (often shortened to SCP: Secret Lab or abbreviated SCP:SL) is a free-to-play multiplayer horror game developed by Northwood Studios. It is based off the Garry's Mod game mode "Breach", which is based off SCP – Containment Breach.


In SCP: Secret Laboratory, five classes compete to survive and complete their objective during a containment breach of anomalous entities in the SCP Foundation Site-02. Players are randomly chosen to play as one of five classes, with each having their own unique strengths, weaknesses, objectives and items.

These classes consist of the Class-D personnel, inmates used for testing with the anomalous subjects; the Scientists, the researchers who work for the Foundation; Facility Guards, security for Site-02; the Chaos Insurgency, a splinter group that seeks to antagonise the Foundation; MTF Epsilon-11, an elite unit sent to rescue the scientists; or one of many hostile anomalous SCPs that now freely roam the facility.
