Five Nights at Freddy's (FNaF) is a 2014 point-and-click survival horror game developed and published by Scott Cawthon. The player takes on the role of Mike Schmidt, a night security guard at a family pizzeria. Schmidt must complete his shifts without being confronted by the homicidal animatronic characters that wander the restaurant at night. The player has access to security cameras to monitor the animatronics throughout the shift, and a set of steel doors that can lock out the characters. Using the cameras and doors consumes the player's limited electricity, and draining all of the power causes these tools to become inoperable.
Cawthon conceived the idea for Five Nights at Freddy's based on criticism of his previous game, Chipper & Sons Lumber Co. Reviewers complained of its unintentionally frightening characters that had animatronic-like movement, inspiring Cawthon to create an intentionally scarier experience. Developed in six months using the Clickteam Fusion 2.5 game engine, Five Nights at Freddy's was released for Windows through Desura on August 8, 2014, and through Steam on August 18. It was made available for Android, iOS, and Windows Phone later in 2014. Versions for Nintendo Switch, PlayStation 4, and Xbox One were released in 2019.
Five Nights at Freddy's received generally positive reviews from critics, many considering it a frightening and distinct horror game. Reviewers praised the atmosphere, sound design, and gameplay mechanics, although some found the jumpscares repetitive and the game to have little replay value. It became the subject of Let's Play videos on YouTube and gained a large fan following. The game's success led to the launch of a media franchise, including sequels and books, and its popularity led to several imitations and fangames. A film adaptation by Blumhouse Productions was released in 2023.
