Five Nights at Freddy's is a relatively short game with a simple concept - work a night shift as a security guard for a pizza restaurant, and try not to get killed in the process.
The game, developed by Scott Cawthon, became an instant sensation on its release and has spawned numerous sequels and spin-offs in the two years since. The series still has a large cult following online today, and fans are waiting in hope of a new game this October.
FNAF is a simple point-and-click game, but it still has a high fear factor, as you are left with rising panic as the nights go on. Unable to move from your spot, you can only click through the security cameras to keep an eye on the various deadly animatronics that lurk about the place, and hope that they don't make it to the office you occupy.
In this clip, YouTube user Smike is working his way through Night 4, when animatronic Freddy seems to appear out of nowhere, as he is wont to do.
