The sequel to the original critically acclaimed game, Outlast 2 is a twisted new journey into the depths of the human mind and its dark secrets. Blake Langermann, a cameraman working with his wife Lynn, must take risks and dig deep to uncover the stories no one else will dare touch. As the two follow a trail of clues that started with the seemingly impossible murder of a pregnant woman known only as Jane Doe, the investigation leads them miles into the Arizona desert to a darkness so deep that no one could shed light upon it, and a corruption so profound that going mad may be the only sane thing to do.

The original Outlast game released in 2013 and takes place in the remote mountains of Colorado where horrors wait inside Mount Massive Asylum. A long abandoned home for the mentally ill, Mount Massive Asylum was recently re-opened by the "research and charity" branch of the transnational Murkoff Corporation, and has been operating in strict secrecy. 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, 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 Whistleblower is DLC that tells the story before and after the events of Outlast to show the final chapter in Mount Massive Asylum's story. Players take on the role of Waylon Park, a software engineer under contract with Murkoff, who identifies with the poor souls housed in the facility. Fueled by his anger, the stage is set for the unmasking of Mount Massive's rotten core.
