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.

    I feel like we're also going to be introduced to someone new that is a huge part of the lore. The creator of the place couldn't be William Afton because he is Glitchtrap because is unable do much. Since one of the endings in Help Wanted showed that the Pizzaplex was under construction. It couldn't be Henry because he dead and all. And it couldn't be Vanny because she is helping Glitchtrap all the time. So I feel like we're going to be shown more characters that are a huge part of the story other than Vanny and other new animtronics.

    But if it was glitchtrap in stage 01 in fnaf 3, why would he give a birthday cake to the crying child in the minigame instead of like, going stabby stabby or something?

    Alright people, i have a dumb thoery but what if tape girl is Vanessa? Like think about! How can tape girl just vanish out of nowhere unless her mind has been taken away by glitchtrap and who else do we know is under glitch rabbits control? Vanny, aka vanessa. Whenever we meet a character in the fnaf lore we see them again another point, example : WILLIAM EXOTIC BUTTER NITPICK SPRING TRAP HOLLADAY AFTON! And micheal to and the animatronics, so tape girl should come back but as another character, like who? Vanny Sorry if this is long and annoying this is just a theory

    So i guess the Vanessa and Vanny are really are both and the same in the upcoming Security breach.. The security Gaurd Vannessa is Vanny and will be torn apart from either OBEYING... or to PROTECT the child... Thus dub the reluctant Follower

    We know security breach is in the 1980's but we also know that's when the missing children's incident happened. But that can't be posable if Afton is already dead. So either security breach takes place in the future or this isn't cannon. Is security breach in the end of the timeline or is this all fake MatPat Or maybe Afton is still alive

    WAIT A SECOND vanny has a suit like an animatronic now this is the future so this could be false and the spring lock suits have been deemed unsafe could this be another spring trap in the making?

    Theory: So since molten freddy and scrapbaby are 2 different people in fnaf 6 what if it's a prequel? Like during fnaf 4 they are still in the works and since the fire happened in fnaf 3 that's why scraptrap looks like that.

    couldn’t the company who made the game have gotten the circuit board out of the fire if it survived? i feel like while cleaning up, if they found the board they would’ve just kinda been like “oh hey here’s another board for you guys!”

    You said that purple bonnie is glitch trap but it is really shadow bonnie

    At this point, I think Scott is just taking whatever Game Theory gives him, sorts through it, and slaps it on a rusty deathly-smelling silver platter.

    The more we talk about this game the more I think that its a messed up game

  • SaberSapphire

    Let me guess the new game if you complete the game and don’t die to vanny the story line is that hiding from her gets so extreme that the anamatronics have to turn gregory into one of them soon accidentally killing him(if that happens may pat ya gotta credit me for being right)

    what if in security breach there was a mechanic where you can hide inside the rockstar freddy suit but if you did for too long then you would either suffocate or get spring locked and lose. so it would be like a hide and seek chase against bendy with a little miracle station animatronic follows you around
