Outlast is a first-person survival horror game series developed by Red Barrels, built around helpless protagonists who must hide and record rather than fight back. The original game became widely known through playthrough videos and streaming, where its asylum setting and relentless chases made it a staple of horror content. Later entries, including The Outlast Trials, kept that same tense atmosphere for a new audience. Ending cues from the series are now reused by creators who want a familiar signal that a frightening run is over, without needing to explain the game itself.
