(This is a remake of FNAF: SB) Destiny has intertwined the fates of two innocent souls, Gregory and Violet Buckley, as they find themselves ensnared within the monstrous labyrinth of Freddy Fazbear's Mega Pizzaplex. Once a place of joy and mirth, this colossal mall and amusement park now morphs into a nightmarish realm where their existence is forever altered. The vibrant hues and cheerful ambiance have been tainted, replaced by unspeakable horrors. Roxanne Wolf, Montgomery Gator, and Glamrock Chica, the once-beloved animatronic mascots, have transformed into relentless hunters, driven by a sinister purpose - to extinguish the lives of these hapless children. Bound together with numerous other captive souls, they forge an unholy alliance, united by the sole desire to survive the onslaught of these mechanical murderers and seek an escape from this living nightmare. Violet, intimately acquainted with the Pizzaplex, possesses an intimate knowledge of its twisted layout, a beacon of hope amidst the darkness. Gregory, a nimble and resourceful young lad, wields his ingenuity to fashion tools from the most unlikely of sources. In the depths of this macabre ordeal, a guardian emerges in the form of Vanessa, a valiant security officer who valiantly battles the nightmarish animatronics with her arsenal of weapons and mastery of martial arts. Her indomitable strength and unwavering resolve become a formidable barrier against the relentless onslaught of these monstrous creations. But the children's salvation lies in the most unexpected of allies - Freddy Fazbear himself. Unlike his malevolent companions, he possesses a compassionate soul, devoid of homicidal inclinations. With unwavering dedication, he becomes their protector and guide, leading them toward safety, sparing no effort to ensure their escape from this hellish domain.

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.
