Zone 13

What are the walls of the invisibility laboratory hiding? Sounds only heard by those disappeared. The silence in "Zone 13" is deceptive. The walls here remember the whispers - those only they heard. Those who dissolved into the air, leaving only cold sweat and records with disjointed phrases: "It breathes behind the door", "They didn't leave, they just became invisible". Sometimes footsteps echo down the hallways. Not yours. Not ours. Theirs. Someone touching wires, dropping flasks, as if the experiments are still ongoing. But the laboratory is empty... or does it just appear that way? They were not supposed to survive. Criminals, traitors, murderers - those who were sentenced to execution or life imprisonment. But instead of a bullet, they faced a different end. "Zone 13" - the last chance to atone for their sins with blood. Not theirs. There are no randoms here. Each was selected for having already crossed a line. A terrorist, a poisoner, a sadist, a rapist - their psyche is broken, their will is suppressed. Perfect subjects. Who would notice if they burn in the experiment? But among them - those who were supposed to control the process. Scientists, military personnel, doctors. Those who knew too much. Those who could not be let go. Now the border between torturers and victims is erased. They are all part of one nightmare. Are you ready to find out how it ended?
