When contacted by email, co-founder Philippe Morin told Polygon the delay was for "additional time to polish, mix the sound and debug."
"We felt it was worth it to enhance the experience," Morin said.
Outlast follows a journalist who, after receiving an anonymous tip, begins investigating a mysterious mountain asylum. Whistleblower takes place shortly before the main events of the game; players take on the role of the tipster who witnesses the chain of events that resulted in the asylum's current state.
