FNAF (Five Nights at Freddy's) is a popular indie horror video game franchise where you play as a night security guard surviving against haunted, killer animatronics at pizza restaurants, famous for its jump scares and deep, dark lore involving murdered children's souls possessing the robots, a sinister murderer (William Afton), and a sprawling mystery. It started with a simple game concept by Scott Cawthon but exploded into a huge multimedia universe with sequels, books, and even a major film, all centered on creepy animatronics, hidden secrets, and survival horror.
