t's 1979. You play as Arnold, a technician dispatched to Murray’s Costume Manor, a long‑abandoned workshop once owned by inventor Edwin Murray

Your task: recover Fazbear Entertainment’s "stolen" prototypes and retrieve the “Mimic,” a next‑gen endoskeleton with unsettling powers , being able to fit in any suit in the facility .

You entered the facility through the back entrance, only to be greeted by a room filled with costumes, animatronics, and suits—all dancing and moving in different ways. A small robotic creature named Mr. Helper slowly emerged from the top of the doorway and joined in with the tune. Miss Helper briefly appeared too, until everything suddenly shut off.

You made your way through the secondary exit and entered a storage-like area. Inside, the air smelled of dust, leather, and discarded dreams—costume parts lay strewn about, and the old, yet strangely clean, suits cast eerie silhouettes under broken lamps.

After finishing the puzzle, you rushed out—only to find the mimic standing at the gate of the door you needed to reach. Thinking fast, you threw a mouse in the opposite direction and sprinted through the door.

You took an elevator up and entered a mysterious room with a large music box in the center. Slowly, you pulled the handle until Jackie suddenly popped out. Startled, you quickly grabbed the handle from the box and ran to the locked gate, using it to open the way forward.

The next hallway was lined with posters of countless strange characters. At the end, you found a “Mail Bot” and carefully made your way to the generator. You pulled the lever—but just then, Jackie burst into the hallway, trying to force her way into the room. She got stuck, and in the struggle, her box broke off, leaving only her arms.

She hurled the Mail Bot across the room, smashing it through the wall and breaking it open.
