The hero of this story agreed to take part in testing a new generation game - and found himself locked in its virtual world. And this is a very gloomy world - the catacombs of two planets, inhabited by the distant descendants of refugees from the Earth suffocating from overpopulation. There, in the underground corridors, squads of combat cyborgs and mutants fight for life and death. Genetically modified flesh, fused with metal and microcircuits, crushes its own kind with rockets and flamethrowers. Synthetic blood flows, mixing with hydraulic fluid from broken hoses, mutated skin, rough as the sole of a soldier’s shoe, crackles and shrinks in the napalm flame. And our contemporary, who finds himself in the shoes of a cyborg mercenary, will also have to fight, kill - and die, retreating to the local bio-cybernetic hell for reformation. But, most importantly, he has to find out who locked him in this creepy virtual reality? After all, there is simply no other way to exit the game.
