On July 24, 2014, Cawthon submitted Five Nights at Freddy's to IndieDB, where it gained massive popularity. He then submitted it to Desura on August 13, 2014, and also submitted it to Steam Greenlight on June 13, 2014, where it was accepted August 18, 2014. A trailer was shortly released on June 14, 2014, with a demo following on July 24, 2014. On August 8, when the game was accepted, the game was released for $4.99 on Steam. The game was well received by critics and became the subject of a number of popular Let's Play videos on YouTube. Scott Cawthon then went on to develop multiple followup games. In April 2015, Warner Bros. announced that they had acquired the rights to adapt the Five Nights at Freddy's game to film.
Soon after the release of Five Nights at Freddy's 2, Cawthon removed all information from his official site and replaced it with an image of the word "offline". The website soon began to show teasers of Five Nights at Freddy's 3, which was released on March 2, 2015. In July 2015, Cawthon released the fourth game of the Five Nights at Freddy's horror series, along with an additional automatic update that was released on October 31, 2015.
On September 15, 2015, Cawthon announced the development of a new RPG, titled FNaF World. The game is not a horror game; rather, a stylized RPG. It was released on January 21, 2016. Four days later, Cawthon pulled it from the store, not satisfied with the results and released an improved version on GameJolt for free on February
On May 21, Cawthon released a teaser trailer for Five Nights at Freddy's: Sister Location, featuring a clown-like animatronic and a dancer animatronic. The first trailer shows four animatronics never seen before and a lot of secrets. The game was released on 7 October 2016 and was not fully free roam but some parts allow you to crawl or walk. Custom night mode was released on Friday 2 December and Golden Freddy mode unlocked soon after.
