Game Theory: FNAF Security Breach, I Know the BIG TWIST... I think
Get our NEW Holiday & Official Theorist x FNAF Merch! ►
We have brand new Holiday Theory Wear + a FNAF x Theory Wear collaboration!
You probably read the title and thought something like, "There goes MatPat, trying to figure out a FNAF game that's not even out yet." Well, you may be RIGHT but you are also WRONG! I'm not "trying" to solve the big TWIST of FNAF Security Breach. All of my days of gathering evidence and researching the Five Nights at Freddy's universe means that I KNOW my stuff. In fact, I know it SO WELL that I can predict - without playing the game - what we will learn that will change the shape of the FNAF story moving forward. What is it? How do I KNOW? Theorists, you'll have to watch to find out.

      okay. So I can no longer ignore all the Glitchtrap clues pointing straight to William like a giant glowing arrow in favor of the possibility of it being Michael. That said, I'm still skeptic about Michael really being dead and I still think the description of that burned body in the hospital matches Michael pretty suspiciously.

    Hi mat I don’t want to be annoying here! But you see in fnaf custom nights and you said it’s Williams hell yet when you play golden Freddy’s mini games in it the audio seems creepy and if you speed it up revers it extra it’s in Doccos video it’s William helloing for help and him saying help and mike and I always come back so why would that be there if it’s William there he wouldn’t be saying that because he’s already there. So what is going on there so can someone help me out with that?

  • RainyNights

    I can’t be the only one who think at this point the theory/lore/story has gone too far right? I feel as if Scott should’ve just ended the series a little after sister location and just completed a story and put the information needed to just finally solve the story. It’s too confusing and too long and dragged out at this point.

    Does anyone else think balloras got something to do with it. The trailer uses her music box song or sounds like her music box song ?? Just listen to both of them they are the same. Ballora may have nothing to do with it but mabey sister location has.

    I think of any is just mentally insane this was the theory before the second trailer in the trailer it says Insanity prevails just like William and if it's glitch trap is just William Afton then William is trying to break Vanessa trying to break her mental state just like his and it is breaking slowly Jeep slowly goes mentally insane each day each day the necessary energy is lost until her sanity breaks just like William Afton sanity in the year 1983 when he lost his child from the bite of 1983 but Batman sanity was breaking slowly and then he started building murder robot to do his bidding and capture children and then he loses his daughter Elizabeth Afton and then his sanity breaks into pieces that is what is going to happen to Vanessa Christianity will break until she snaps haaaaahaaaaa HAAAAAAAAAA!

    On the outside screen, if you look on your right there is supposedly the picture of Vanny/Glitchtrap showing up in the last seconds of it. Now, this is just an idea, but maybe it is one of the two.

  • MurrDurr

    OK I HAVE A GOOD IDEA FINALLY, i need support so he can see this soon. But i realized because of the nightguard in security breach being Vanessa, and Vanny being her killer self, she switches between the nightguard and Vanny because Glitchtrap is like a switch, he turns on and off, and Vanessa wants to help Gregory escape before Glitchtrap takes full control

    Fazbear Ent calls the virus in Special Delivery, the C virus. It's strange for a virus to be called that, let alone Afton is now a virus. The C virus could stand for Cassidy, making the animatronics go after people. In the Fnaf book, Jake has the intention to attack people, but he doesn't want to kill them, he just wants to scare them. When you listen to 1 of the voice lines that Freddy and Foxy say, they mention to the player: Are you scared yet? The biggest thing that I found crazy, is that Illumix revealed Golden Freddy will be in the game. That made we wonder to how that's even possible, let alone the strange noises he makes when you're facing him. The noises sounds like Cassidy is trying to fight William. In the Fnaf story, the man in room 1280, William is in a coma, and a brain scan shows he's fighting against something to be in control, and that something is Cassidy. We're in a new era of Fnaf, but instead of the animatronics being possessed by murdered children, they're under the influence of the one that did the murders, William Afton. Anyone in 2021???
