PROJECT BOX takes place only a day or two after the ending of The Twisted Ones. Charlie [the player] wakes up, once again in the underground pizzeria. However, this time she is in a room she has never been in before, and it doesn't look like she’ll be able to leave it so easily. Patronized by Springtrap, Charlie has no other choice but to survive the horrid nights, and solve the mystery shrouding her late father during the lonely days.
