The game was first announced with a teaser that was posted on Scott's website on December 6, 2014. Several more teasers on his website followed, the next being an image of a yellow animatronic in disrepair with the words "I'm still here" on the image along with a small 3 in the corner, this image being added on January 2, 2015. The last teaser image he revealed on his website was an image of a box full of parts from the Toy animatronics, parts from some old animatronics, and some other objects, such as a paper plate man. A yellow figure can be seen standing next to the box. The file's name was "whatcanweuse.jpg".
On January 26, 2015, Scott released the teaser trailer for Five Nights at Freddy's 3 on its Steam Greenlight page, the page also containing various in-game screenshots.
The game was officially released on March 2nd, 2015 - first, as a demo given out to Let's Players on Twitch.tv and YouTube, then hours later as a full game available to the public on Steam. An Android version was released on March 7th, 2015.
History
- On December 6, 2014, when brightened, Scott's website had a very large number three on the bottom right. This is possibly hinting at a third installment to the Five Nights at Freddy's series.
- On January 3rd, the "offline" image was replaced with a picture of a deteriorated animatronic suit's face looking out from the darkness with the accompanying text, "I am still here."
- On January 14th, the deteriorated animatronic image was replaced with a picture of the Animatronics' empty heads, including the Paper Plate Man, inside a box. A big, red "3" is seen above them. When the image is brightened, one can see the full deteriorated animatronic from the first teaser image to the right of the box.
- On January 26, after the trailer's release, Scott replaced the image on his website with a black image with very light text that reads "He always does".
- On February 3, an image on Scott's website appeared to have a map on it with an icon that reads "YOU" and an arrow across from said icon.
- On March 1, the image was changed once more on Scott's website of an image of Balloon Boy that reads "Guess Who?" with a faded 10 on the bottom left hand side.
- On March 2, Scott released another image of Chica and Foxy that reads "It's all in your mind".
- On this same day, Scott released a demo to a number of Let's Players on YouTube and Twitch. Hours later, the full game was officially released to the public.
