Fans of Choo-Choo Charles Revenge will appreciate the shared focus on evading a relentless monstrous pursuer across hostile terrain while piecing together an escape route.

How to play

Each chapter presents a specific objective required to advance to the next part of the school grounds. You will need to inspect rooms, find keys, repair broken equipment, and lead characters away from danger zones.

• Use the mouse to interact with the environment, inspect objects, and use items from your inventory.
• When moving through 3D sequences, press W, A, S, and D to navigate corridors and steer your character, using the mouse to adjust your camera view.
• Pay close attention to sound effects, as the volume and direction of sirens signal how close the creature is lurking.
• Keep an eye out for hiding spots such as lockers, desks, and side rooms whenever the siren audio intensifies.

Survival tips

• Listen before moving: Sound design is critical in every chapter. If the siren sirens grow louder or distort, stop moving and seek cover immediately behind walls or furniture.
• Check every container: Items needed to unlock doors or disable alarms are often tucked into lockers or high shelves. Search every corner thoroughly before advancing.
• Memorize escape routes: If Siren Head spots you, hesitation is fatal. Always identify a retreat route before entering an open courtyard or long corridor.
• Plan your interactions: Clicking randomly can cause unnecessary noise. Plan your actions and use tools only when you have identified the matching puzzle lock.
