Whistleblower will once again take place in Mount Massive Asylum and, according to Red Barrels, “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 addition to new maps and characters, Whistleblower will offer more insight into the “dark history” of the Murkoff Corporation. Players will also “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.”No specific release date has been revealed, but look out for more info in the weeks to come.Outlast was released on PC in September and will come to PlayStation 4 in the future.
