OLD Fredbear Friends: Reboot is a discontinued FNaF fangame that serves as a tribute to the original game. Although it is no longer being actively developed, the developer, Penumbral Studios, has announced a better sequel with improved mechanics, visuals, and lore. The game offers a public demo version with two nights of gameplay.

The story of OLD Fredbear Friends: Reboot takes place a week before the accident that occurred in the game's universe. Players assume the role of a nightguard tasked with preventing any robberies or break-ins while also keeping an eye on the animatronics. These animatronics are known to move around at night, adding to the suspense and challenge. After completing night shifts, players have various tasks to complete, such as repairing animatronics and performing maintenance. Once the work is done, players can enjoy their free time before heading home.

It's important to note that the game includes data saves, allowing players to progress and save their game at certain points during the night.
