You play as the brother of the night-guard from the second game. Try to prevent Goldie, Trina, Tucker, Fishy, and Reaperfish from entering your office. The other instructions are in the game if you listen to the voicemail. Try to survive until 8 AM. Btw, the game will only start if you press 1 to listen to the voicemail or press 0 to ignore the voicemail.
Thanks to Scott Cawthon for making fnaf games so some of the credit goes to him but the rooms and characters were made by me. No advertising! Advertisements will be deleted, I check all comments >:(
