Outlast is a first person survival horror game released by Red Barrels in 2013, set in the abandoned Mount Massive Asylum in Colorado. Chris Walker is its most feared Variant, a huge former soldier who hunts journalist Miles Upshur throughout the game while muttering about containment. His dedicated chase music became one of the game's signature sounds online, reused in horror edits, memes and livestream alerts alongside other gaming staples like the FNAF jumpscare scream. Players still associate the opening hit with needing to sprint for a locker.
