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!

Amidst the chaos of a disastrous mass containment failure at the supposed “master site” Site-02, you fight your way to the top alongside — and against — other players. From devious D-Class and cunning scientists to elite Mobile Task Force units (MTF), rebellious Chaos Insurgency (CI), and even the horrific SCP Entities, there are many key roles to play in this gruesome affair, so... How will you act amidst a containment breach?

SCP: Secret Laboratory (SCP: SL) is a free-to-play multiplayer horror game heavily based on the SCP Foundation series and its expanded universe of monsters and paranormal phenomena. The primary objective of the SCP Foundation (also “the Foundation”) is to safeguard the world from any and all entities, objects, or phenomena that are deemed potential threats to humanity, and thus to uphold the normalcy of the modern world. Recently, however, Chaos Insurgency forces have begun acting against the Foundation in pursuit of a future where humanity reigns supreme.
