S.T.A.L.K.E.R. The Sixth Step

During an operation of the Center for Anomalous Phenomena to seize a shipment of missing artifacts, almost the entire team—experienced stalkers—dies. The sole survivor, Borland, falls under suspicion. Detective Viktor Korneev takes on the case and must figure out what happened at the site—and why Borland decided to destroy his own team. However Borland’s former partner, Mark, believes his friend was framed. They join forces to determine the circumstances, especially since the dangerous cargo is already out in the open. They have only one clue, and it is extremely unusual: a fake note in the melody that played during the operation. Viktor and Mark must solve a complex task to prevent an even bigger tragedy.
