About SCP: Secret Laboratory

✦ AI summary

Survive a massive containment breach at an SCP Foundation facility by playing as one of five factions—scientists, guards, prisoners, elite task forces, or insurgents—each with conflicting objectives in a sprawling underground complex. Fight supernatural horrors, rival players, and environmental hazards in this free multiplayer horror game where cooperation and betrayal are equally viable strategies.

Deep within one of the SCP Foundation’s emergency containment sites, a catastrophic containment breach leads to multiple SCP subjects being released from their cells. With containment compromised, facility personnel rush to evacuate while waiting for Mobile Task Forces to arrive and restore order, but with the Class-D population running amok in a desperate attempt to escape, along with the involvement of the Chaos Insurgency, the fate of Site-02 remains uncertain. SCP: Secret Laboratory (SCP:SL) is a free-to-play multiplayer horror game where you must escape from fearsome entities, or fight to secure a facility under the control of the SCP Foundation, an organisation which seeks to secure and contain anomalous items and creatures in order to protect humanity. These objects, or SCPs, range from mundane-looking items with extraordinary effects, to horrific abominations capable of bypassing the most impenetrable containment methods the Foundation puts in place.Throughout the game, you will witness the perspective of the 5 different human classes, each trying desperately to survive. These include:
  • Scientists: Foundation personnel caught in the midst of the chaos, they must work with Facility Guards and the Mobile Task Force while using their equipment and wits to escape.
  • Class-D Personnel: Prisoners and test subjects using the breach to their advantage, they start with nothing and will do anything it takes to escape from the Foundation.
  • Facility Guards: The woefully unequipped first responders who must help the Scientists escape, prevent the Class-D from escaping, and hold back the SCPs for as long as possible until the Mobile Task Force arrive.
  • Mobile Task Force: Specialised re-containment agents sent into containment breaches to restore order and eliminate threats, they are tasked with assisting in the evacuation of Scientists and taking down anything that poses a threat to the Foundation.
  • Chaos Insurgency: Soldiers of an unknown directive, who are ordered to attack major Foundation sites and terminate all Foundation personnel. They also aim to rescue Class-D Personnel in order to gather useful information from them.
Site-02 is a sprawling maze of different zones. Light Containment Zone, where Scientists and Class-D Personnel reside. Heavy Containment Zone, where the SCPs are contained. Entrance Zone, where Facility Guards are stationed, and Surface Zone, where the evacuation point is located, along with the insertion points for Mobile Task Forces and Chaos Insurgents. The site is prepared for these breaches, containing numerous emergency measures — from Tesla Gates able to electrocute anything caught in the blast, to emergency bulkheads able to temporarily hold back threats from a fleeing target, or even the on-site nuclear warhead capable of vaporising the entire underground section of the site.Despite all the security precautions and safety measures, Site-02 is not impenetrable. Fight alongside and against other players in order to help the Foundation restore containment and order, sabotage the site as the Insurgency, or kill everyone as a SCP in a murderous rampage.
