Survival depends on your ability to move quietly and hide efficiently. The game is fully optimized for responsive, stealth-focused inputs.

💡 Strategy & Walkthrough

• How do I avoid getting caught by Sister Madeline?

  Listen before you leap. Sister Madeline has incredible hearing and will track your noises. Dropping an object, walking on broken glass, or running will immediately draw her to your location. Always listen for the sound of her heavy footsteps or humming before entering a new hallway.

• What should I do first when starting the game?

  Focus on the First Escape Route. Your initial goal is to find the Main Door Key. This usually involves solving multi-step horror puzzles, finding fuses to restore power to the generator, and safely scouring the gymnasium and classrooms for hidden lock codes.

• Where is the best place to hide if I am spotted?

  Do not just run in a straight line—break her line of sight first! Once you turn a corner, quickly dive into a hiding spot. Lockers, under-bed spaces, and the school's tight ventilation shafts are your best tools for surviving a direct chase.

• How can I safely explore a highly guarded area?

  Master the art of "Sound Baiting." Because the AI relies heavily on audio, you can intentionally drop an item (like a bottle) or make a loud noise to lure the Nun to one area. Once she investigates the sound, quickly take a back staircase to search the opposite side of the school completely undisturbed.
