Red Barrels Games have confirmed the release date for the first batch of downloadable content in their survival horror game, Outlast.

The Whistleblower downloadable content will be available in April for both PC and Playstation 4. This expansion will showcase the events that lead up to the main story of Outlast, but it also provides some closure in a final chapter for the Mount Massive Asylum story.

Check out the official synopsis for the expansion:

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.
