From the Press Release
Red Barrels today revealed the first details for its upcoming DLC, Outlast: Whistleblower. Starting just before the events of the original game, Outlast: Whistleblower will take players on another horrifying journey through Mount Massive Asylum and into the depths of the human mind. As the whistleblower whose anonymous tip brought original protagonist Miles Upshur to Mount Massive on one fateful night, you’ll encounter the experiments and abuse (conducted in the name of science, of course) that led to the asylum’s downfall – in fact, your encounter may be a bit too close for comfort… Explore the asylum minutes before the slaughter, then experience the outbreak firsthand. If you can survive, you’ll find new environments and meet terrifying new characters in another quest to uncover truths which were never meant to be revealed.
