They call her ATRI. Anomalous Territory of Radioactive Radiation. A layer between our world and the parallel one. At first glance, it is impossible to survive in these lands. Natural anomalies strive to be torn into pieces, frozen in an instant, or turned into a bloody pancake. Mutant predators try to devour everything that moves. And people... They always have something to share, something to fight for. Military operations in ATRI do not stop for a moment. People fight among themselves, fight with primitive homo sapiens from a parallel world, mutant predatory animals and nature itself. A local war here will not surprise anyone. Yet the attack on the oil refinery was an extraordinary event. A squad of rangers, free vagabonds and rogue mutants set off on the trail of the mysterious enemy. Nobody trusts anyone, everyone is watching each other. And they are doing the right thing, as it turns out, each of them has something to hide. Among them is a Bedouin. It seemed that the simplest task for the former reconnaissance saboteur was to track down the enemy. But in ATRI there are no simple tasks. Nothing here is what it seems. A partner can suddenly hit you in the back, shielding the enemy from the bullet. And whether you live or die will be decided by a small piece of lead, a single cartridge, not without reason nicknamed “Nine grams for luck.”
