In the remote mountains of Colorado, horrors wait inside Mount Massive Asylum. A long-abandoned home for the mentally ill, recently re-opened by the “research and charity” branch of the transnational Murkoff Corporation, the asylum has been operating in strict secrecy… until now.

Acting on a tip from an anonymous source, independent journalist Miles Upshur breaks into the facility, and what he discovers walks a terrifying line between science and religion, nature and something else entirely. Once inside, his only hope of escape lies with the terrible truth at the heart of Mount Massive.

Stealth-based gameplay, with parkour-inspired platforming elements.
You are no fighter - if you want to survive the horrors of the asylum, your only chance is to run... or hide.
Outlast’s setting and characters are inspired by real asylums and cases of criminal insanity.

Included DLC: Whistleblower

Requires Mac OS X 10.9 or later
