In a fit of drunken nostalgia, he will ask you to learn about their fate, promising a reward.
Having received from the Cardan quest "Three comrades", the first thing to go to an abandoned gas station, near the cleft. When he reached it, turn to the West, to the grove, which is about anomaly "Sosnodub". Addresses on the way from a pack of blind dogs and looking at the body of Stalker.
Found in thick grass picked clean skeleton, inspect the ground around looking for a PDA. It can be easy to find, thanks to the luminous screen. Pick up the computer and records it, find out that the skeleton belongs to a Stalker named Joker.

Reach the ruins and search them. In the absence of the body farm, the hero of the game will come to the conclusion that the Barge went down in the cave.
Go down to the base of the hill and find the entrance to the cave. One failure leads to a small cave with a monster controller, however, among the piles of dead bodies you Barge will not find. The second failure leads deep underground. Go down it and you will find yourself in an extensive but closed network of caves and tunnels.
Using a flashlight or night-vision goggles, methodically scour every nook and cranny of the cave, paying special attention to the puddles "soda". In the end, one of the anomalies you find the twisted body of the Stalker. Pick up his PDA and make sure that it is a Barge. Take PDAs Barge Cardan.
