Kidnapped, and alone, a young orphaned boy named Gregory escapes confinement and finds himself in a cat and mouse game, inside the Freddy Fazbear Mega Pizzaplex. He is being hunted down by the animatronics that roam the Pizzaplex, and all of them have become merciless killing machines who seek nothing more than the blood of their victims. While Gregory tries to survive, he quickly realises he's not the only kid who's in this facility, for many more children like him roam the building, trying to survive the animatronics. The Pizzaplex has become a mall from hell, and the robots keep picking off each kid one by one. However, Gregory isn't completely alone though, for he soon gets help from a young security guard and one of the animatronics, and the trio do their best to survive and discover the secrets of the Pizzaplex. However, the journey for the young Gregory won't be so safe, for the horrors he had witnessed catch up to him, and the atrocities he sees in this establishment slowly makes him loose his grip.

A complete rewrite of the game Security Breach. This takes concepts introduced from the games and books and implements them into the setting of the mega pizzaplex. This is not about theories. In fact, it's probably going to be far off from canon. This is just how I would've handled the story of Security Breach.
Gregory sneaks into Freddy Fazbear's Mega Pizzaplex in order to uncover the secrets of the pizzeria and find information about the recent disappearances from within. During the five nights he stays inside the pizzeria, he befriends animatronics, discovers information about not only the recent disappearances, but also the dark history of Fazbear Entertainment, all while he has to avoid being killed by rabid animatronics and whomever this mysterious "Vanny" is.
