About this game
High School 53: Erebus Protocol "When the government contract ends, hell begins." Overview High School 53: Erebus Protocol is a first-person survival horror experience that blends psychological terror with cutting-edge technology in a grimly realistic setting. The game takes place inside an abandoned government education facility in the heart of Saudi Arabia, concealing a secret system that transcends all moral boundaries. In this place, laws no longer exist… only experiments. You are not a hero. You are not equipped to fight. You are just a maintenance technician… who walked into the wrong place. Story Lumina secured a lucrative contract with the Ministry of Education to develop advanced systems. But behind the official facade lay a very different reality. The facility was a cover for a secret headquarters of Erebus, a shadowy entity that reshapes humans through inhumane experiments. After a mysterious incident leads to the site's official closure, Ahmed, a maintenance technician, is sent on a routine nighttime assignment to fix a technical glitch in the basement. But as soon as he descends into the basement, the full isolation protocol is activated. Connections are lost. The doors lock. The place becomes a cage. You are now inside Erebus. And you are not alone. Key Features Two-Layer Horror A visual and psychological contrast between a familiar educational environment… and a terrifying underground surgical facility. Every transition between them increases the tension instead of easing it. Tablet System Your device is not just a tool… it's your only means of survival. Hacking through cameras, decrypting codes, controlling doors, and accessing archives that must never be opened. Adaptive Behavioral AI Enemies don't just "hunt" you. They learn you. They remember your hiding places, change their behavior based on your fear, and communicate indirectly. Every decision you make… has consequences. The Technician's Arsenal No firearms. No easy escape. Rely on your tools: Close doors to isolate the threat Stun devices to temporarily disable enemies Manage resources under pressure Every encounter is a risk. Complete cinematic realism No…
