High School 53: The Erebus Protocol

Game Overview

High School 53: The Erebus Protocol is a psychological and technical first-person survival horror game set inside an abandoned government school in Saudi Arabia, where the educational building hides a darker underground facility connected to a mysterious organization known as Erebus and a technology company called Lumina Corporation.

The story begins when Ahmed, an ordinary maintenance technician, is sent on a nighttime assignment to repair an electronic failure inside the school after its official closure. The task sounds simple: enter, inspect the system, repair the fault, and leave.

But once Ahmed reaches the inner area, the self-isolation protocol activates. Doors lock. Communications die. Emergency exits stop responding. The facility begins treating him as an intruder that must be contained.

What looked like an abandoned educational building slowly turns into an underground nightmare of secret laboratories, containment rooms, surveillance systems, encrypted archives, and human experiments that have gone out of control.

You are not a soldier. You are not a hero. You do not have firearms. You are a maintenance technician who entered the wrong place on the wrong night.

Story

Years earlier, High School 53 received a major contract to develop a modern educational infrastructure connected to advanced technology systems. On paper, the project was part of school modernization and digital transformation. Under that cover, an underground facility was being used for illegal human research connected to Erebus.

After a mysterious incident, the school was officially shut down. Reports blamed structural issues, operational failures, and the end of the project. The truth is that what exists beneath the school never stopped.

The systems are still running. The cameras are still watching. And the thing buried below is not dead.

When Ahmed enters the site, he discovers that the closure was not meant to protect people from the school. It was meant to protect the world from what was inside it.

Player Character — Ahmed

Ahmed is a professional maintenance technician, but he is an ordinary human being. He has no combat training and does not know the truth of the place before entering. His strength comes from practical experience: reading panels, handling faults, understanding systems, and using available tools intelligently.

Ahmed makes the horror more grounded. He does not enter the place to save the world. He enters because he was doing his job. That makes the situation harsher.

Horror Style

The game does not rely only on jump scares. Horror is built through constant pressure, silence, distant sounds, disturbing files, places that look too clean, and the feeling that the facility is watching you.

The real horror is not only in the monsters. The real horror is in the system that created them.

Art Direction

The game uses a realistic cinematic visual style. The school feels familiar and abandoned, while the underground facility becomes a cold, technical, medical, and disturbing world.

Lighting relies on believable sources such as emergency lights, weak fluorescent tubes, server lights, the handheld flashlight, and reflections on glass and metal. The goal is a believable world, not just horror decoration.

Audio

Audio is central to the experience. The player hears Ahmed’s breathing, footsteps, electrical hum, moving cameras, distant doors, sounds inside ventilation, and interference from old devices.

Music is rare and limited. Silence itself is part of the horror.
