Aside from all the evil animatronics that have been chasing you all over the pizza house throughout the previous chapters of FNAF, there are also other, even more dangerous villains lurking in the shadows. We are talking about William Afton, a person who created Freddy and his friends. He was a mentally ill man who murdered people dressed up as one of the animatronics. That’s why he is now as the Killer in Purple. Tonight he is setting his eyes on you. You have to be very attentive and careful if you want to survive in this intense struggle!
