1975, East Germany. You are declared an “enemy of the state” based on unknown espionage charges. You, your family, and the Weltel family are abducted by a secret unit of the regime and taken to an illegal, off-the-record underground facility beneath Oreinburg. This is a dark laboratory where experiments known only by the code name Protocol X are conducted.

Chemical and psychological experiments in this facility have spiraled out of control, irreversibly altering human minds and bodies. If you don’t act, you will lose both your family and the Weltels.

Your mission is clear: Descend into the reactor, shut down the system, bypass security protocols, and return to your home in the village by saving everyone. However, this mission leaves your fate entirely to your choices.

This is a historical story shaped by multiple endings: Every decision you make—who you trust, who you save, and how you face the dark truths—will determine your future.

And remember… Getting out of the facility alive is only the beginning
