The third FNAF game came out on March 2nd, 2015. Many trailers were released to hype up the game. Including one with the words "I am still here." You can see a bit of Springtrap next to the words, and this was the first the community saw of the game's main antagonist, Springtrap. A little fun fact is that if you take the photo and brighten it, you can see the number three in the bottom right, hinting at how this is the third game of the series. Another trailer shows the map to FNAF 3.
If you brighten the photo up, you'll see secret pathways. These end up being the vents that Springtap can sneak through.
Thought 10 animatronics was too much? So did Scott! In the third FNAF game, you play as a security guard in the future (or present now) in 2023 in a horror attraction based on the stories about Freddy Fazbear's pizza. And this time, you only have to defend yourself against one animatronic! All you have to do is lure the animatronic to a room using an audio lure, and the occasional sneaking through the vents won't be too much of a problem. And unlimited power! Too good to be true, right? Right.
There are hallucinations of Phantom animatronics that will cut off power for cameras, audio, and ventilation, and those take a very long time to fix! Like I never said, there's always a twist. Just survive for 5 nights, and you win!
