About the Game

SCP: Classified Site takes the haunting atmosphere of the beloved SCP: Containment Breach and transforms it into a fully online multiplayer experience. Rooted in the creative universe originally built by Undertow Games and Third Subvision Studio, this game is licensed under the Creative Commons Attribution-ShareAlike 3.0 License, honoring the community-driven origins of the SCP Foundation mythos. Rather than navigating the horrors of a containment failure alone, players now face them together, or against one another, depending on which side they choose.
At the heart of SCP: Classified Site is a role-based multiplayer structure that gives every player a unique position within the chaos of a containment breach. Here is a breakdown of the available roles and what each one brings to a session:
Class-D Personnel: Expendable test subjects trying to survive and escape the facility against overwhelming odds.
Scientist Personnel: Researchers with access to certain restricted areas, navigating the breach while trying to stay alive.
Security Guard: Tasked with maintaining order inside the facility and protecting key personnel from both SCPs and hostile factions.
Mobile Task Force (MTF): Elite operatives deployed to recontain anomalies and neutralize threats, working with coordinated tactics.
Chaos Insurgency: A rogue faction opposing the Foundation, entering the site with their own agenda that often conflicts with everyone else.
SCP: Players can embody the anomalous entities themselves, becoming the very threat others are trying to escape or contain.
This variety of roles means no two sessions play out the same way. The balance of power shifts depending on how many players align with each faction, what decisions are made in the early moments of a session, and how effectively teams communicate. A coordinated MTF squad can quickly turn the tide against a rogue SCP, while a well-organized Chaos team can destabilize the entire facility from within.
The game draws its tension from the source material. The SCP: Containment Breach universe is known for its oppressive atmosphere, unpredictable anomalies, and a sense of constant vulnerability. SCP: Classified Site carries that tone into multiplayer, where the added layer of human opponents makes encounters even less predictable. You cannot simply memorize patterns when every other player is making their own choices in real time.
For players who want to engage with this experience on a bigger stage, MuMuPlayer allows you to run SCP: Classified Site on PC. The expanded screen gives you a wider field of vision as you move through the facility, which matters enormously in a game where threats can come from multiple directions. Precise keyboard and mouse controls also allow for quicker, more deliberate movement compared to mobile touch inputs, giving you a competitive edge in high-pressure moments. Whether you are coordinating with teammates as an MTF operative or hunting lone survivors as an SCP, the control precision that comes with PC play through MuMuPlayer makes a meaningful difference in how well you can perform your role.
