The SCP Foundation was created to protect humanity. Now it wants humanity dead. Without warning, the Foundation turns against the world it once defended, unleashing its anomalies, weapons, and horrors upon mankind in a brutal campaign of extinction. Cities fall. Governments collapse. Entire populations vanish overnight. At the center of the apocalypse is a single survivor: Pietro Wilson. Hidden inside an experimental suit that makes him impossible to perceive, Pietro travels through the ruins of civilization searching for answers. Why has the Foundation declared war on humanity? What terrible truth did they discover? And why would the people sworn to Secure, Contain, and Protect decide that human extinction is necessary? As the world descends into nightmare, Pietro uncovers classified files, impossible entities, and fragments of a secret so horrifying that even the Foundation itself could not endure it. SCP-5000: The End of Humanity is a dark science-fiction horror story set within the SCP Foundation universe - a chilling journey through paranoia, cosmic terror, and the collapse of reality itself. Because the most terrifying question is not how the world ends. It's why.
