Five Nights at Freddy's 4

Five Nights at Freddy's 4 removes cameras, power meters, and doors entirely, closing out the original storyline in a dark bedroom where the only tools are your ears and a flashlight, and the threats are Nightmare versions of animatronics that don't wait for a system failure to attack.

Because there's nothing to watch on a screen, every check has to happen live and close, listening for breathing at each door before closing it, flashing the closet before Foxy fully emerges, and glancing at the bed rather than assuming it's empty. Reacting a beat too slowly to breathing costs far more here than a missed camera check would in earlier games, since there's no second system to fall back on if a door check goes wrong. Five Nights at Freddy's: Sister Location moves the series into an entirely different underground facility next.
