In Five Nights at Freddy's, you're the security guard who must keep the robots at bay each night. You watch the giant animals on a series of security monitors – until your limited power supply cuts out and the lights go dark. Then all of the doors are disabled and you're at the mercy of whatever lurks behind those giant, dead eyes.
Yeah. Nightmares. Five Nights at Freddy's was Greenlit via Steam and is now out on PC for $5. One dollar for each night, or for the number of times you'll say "NOPE" and force quit the game. Per minute.
