Evaluation
Outlast launched on September 4, 2013 as a complete first-person survival horror game. It received one paid DLC — Whistleblower — which released on May 6, 2014, adding a prequel story to the base game. A patch in April 2014 added achievements, a new difficulty mode, and DLC support. The game was later ported to Mac and Linux on March 31, 2015. In November 2015, Red Barrels announced Outlast 2 as a separate sequel title. There are no unreleased DLC items, no announced future content for this game, and no developer communications suggesting additional content is planned. The last developer activity related to Outlast itself dates to the Mac/Linux port in March 2015. The game shipped as a complete product and has received all of its planned content.

About this game
Hell is an experiment you can't survive in Outlast, a first-person survival horror game developed by veterans of some of the biggest game franchises in history. As investigative journalist Miles Upshur, explore Mount Massive Asylum and try to survive long enough to discover its terrible secret... if you dare.
Synopsis:
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.
Outlast is a true survival horror experience which aims to show that the most terrifying monsters of all come from the human mind.
Features:
Warning:
Outlast contains intense violence, gore, graphic sexual content, and strong language. Please enjoy.
