Among the inviolable laws of the New Zone is this: all old matters remain within the Perimeter. Whoever you were before you got into the Zone, and whatever enmity previously connected you with your comrades in the stalker craft, don’t remember it. Shkval, a fighter of the Hydra team, the best team of underwater stalkers, strictly followed it and lived the ordinary life of a free vagabond: hunting for mutants, searching for artifacts, and in between - riotous recreation in bars. That was until he met Major Barsukov on his way - a man from his past life, once a comrade in arms, and then his worst enemy. And Shkval accepted this challenge. Moreover, the stake was the legendary “Dead Man’s Chest” - a container with unique artifacts resting at the bottom of the Novomoskovsk Sea. However, fate itself intervened - the Wild Rush hits the Moscow Zone and hordes of mutants are ready to break out into the outside world. And it’s up to Shkval and his comrades to stop them. This battle will be very difficult to win and survive. And it’s even more difficult to remain human.
