Protocol X

1975, East Germany. Accused of an unknown act of espionage, you are labeled as “anti-system.” You, your family, and the Weltel family are abducted by a secret state unit and taken to an unregistered underground facility beneath Oreinburg - a place hidden from the public where the covert Protocol X experiments are conducted. The chemical and psychological tests carried out here have spiraled out of control, leaving irreversible effects on the human mind and body. If you don’t act now, both your family and the Weltel family will be lost. Your mission is clear: Descend to the reactor, shut down the system, bypass security protocols, and escape with everyone back to your village home.
