Stalker: Call of Pripyat → Quests → Attack
In both cases, you’ll receive a reward. And also a trophy weapon, which is better than the starting one… And yes, if you decide to support the stalkers, wait until the bandits form a single line, then throw a grenade into the center of the line. There won’t be many survivors.
Sultan, the bandit kingpin, asks for help with a dirty deed. He wants to kill some stalkers on a nearby barge, the “Shevchenko.” The attack will take place at midnight. You can help him and attack the stalkers. Or you can tell Boroda, the bartender, about this mission.
