Outlast is scheduled to receive its first downloadable content, Whistleblower, this April on both PC and PlayStation 4.
Developer Red Barrels revealed details about the expansion on their Facebook page:
Whistleblower will let you play as Waylon Park, a software engineer under contract with Murkoff and the man who emailed journalists around the world – including Miles – at the beginning of Outlast. Spending a couple of weeks at Mount Massive, during which he was unable to even talk to his wife and son in Boulder thanks to strict security protocols, Weylon developed a deep-seated distrust of the profit-motivated scientists and doctors leading dangerous and irresponsible experiments on their patients. Identifying with those poor souls fueled Weylon’s anger, and set the stage for his unmasking of Mount Massive’s rotten core.
Outlast: Whistleblower is a prequel which tells the story that led to Outlast, and will go beyond the events of the first game to provide answers to questions left open in the original game.
