SCP-173 is one of the best-known creatures from the SCP Foundation, a collaborative horror-fiction project, and it became a central threat in SCP: Secret Laboratory, the multiplayer horror game based on that universe. In the game, players must watch the concrete statue at all times because it moves when unobserved, and a containment breach turns a routine round into a frantic escape. Clips of its alarms and breach moments spread through gameplay videos and horror edits, where the sound now signals sudden danger even for viewers who have never played the game.
