1941, June 21... Tomorrow the deadliest war in human history will begin. And on this day, at the border between the USSR and Germany, a stalker nicknamed Sniper appears—someone whose will, under the direction of the Monument, was thrown from the Chernobyl Zone into the past. He knows what will happen in a few hours, but what can one person do against the deadly armada of the Wehrmacht—especially since here, at a Soviet border outpost, no one believes him? But Sniper wouldn’t be Sniper if he had just accepted the situation. The war can’t be stopped, but many Soviet soldiers’ lives can be saved. He will try to destroy the plans of the mysterious fascist organization “Ahnenerbe,” and to destroy the man-made monsters in the undergrounds of Chernobyl... and, perhaps, to uncover the secret of the Monument that appeared long before the terrible accident at the Chernobyl nuclear power plant.
