SCP: Secret Laboratory is a free-to-play multiplayer horror action game set in the secretive world of the SCP Foundation, where players navigate a chaotic containment breach in an underground facility.
Gameplay
In SCP: Secret Laboratory, the core experience revolves around asymmetric multiplayer matches where participants take on various roles during a facility-wide anomaly escape. You might spawn as a Scientist, scrambling to flee with limited tools, or as a Class-D prisoner, scavenging for weapons to break out. Facility Guards act as initial defenders, holding the line against threats until reinforcements arrive. The gameplay emphasizes survival, teamwork, and betrayal, with mechanics like activating Tesla Gates to zap intruders or sealing bulkheads to block paths. Players can also trigger a nuclear warhead as a last resort to contain the breach. Combat involves firearms, SCP abilities, and environmental hazards, all within a maze-like site divided into zones such as Light Containment for starting classes and Heavy Containment for anomalies.
Mechanics encourage dynamic interactions, where human classes must cooperate or compete to achieve objectives like evacuation or re-containment. SCP entities, which players can control, possess unique powers to hunt others, adding horror elements through pursuits and ambushes. The game's Unity engine supports fluid movement and voice chat, fostering tense alliances that can shift based on role assignments each round.
Game Modes
The primary mode in SCP: Secret Laboratory is a round-based multiplayer scenario focused on the containment breach event. Matches unfold in real-time, with players assigned to roles at the start, aiming to fulfill faction-specific goals like escaping the facility or restoring order. This setup supports up to dozens of participants per server, blending elements of hide-and-seek with tactical shooting.
While there are no distinctly named alternative modes, community servers often host variations with custom rules, though the official experience sticks to the core breach simulation. Recent updates have refined balance, such as adjustments to SCP abilities and class spawns, keeping the mode fresh as of early 2026.
Factions and Classes
SCP: Secret Laboratory features distinct factions that drive the conflict. The SCP Foundation side includes Scientists, Facility Guards, and Mobile Task Force units, all working to secure anomalies and evacuate personnel. Opposing them is the Chaos Insurgency, which infiltrates to terminate Foundation staff and extract Class-D Personnel for intelligence.
- Scientists: Equipped with keycards and knowledge, they collaborate to navigate exits.
- Class-D Personnel: Start unarmed but can loot gear to aid their escape attempts.
- Facility Guards: Armed responders who protect Scientists and contain threats early on.
- Mobile Task Force: Elite squads that enter mid-game to eliminate dangers and assist allies.
- Chaos Insurgency: Invaders focused on disruption and recruitment.
- SCPs: Playable anomalies with abilities like instant kills or regeneration, tasked with preventing escapes.
