Deceive the Deceiver: Stalker 2 Quest Walkthrough

After talking to Zakhar in S.T.A.L.K.E.R. 2: Heart of Chornobyl, you will learn that the stalker who offered you the job in the quest A Big Score wanted to set up both you and David, so the hero decides to take revenge.

Find the corpse of the stalker nicknamed Sanya Dobryak, take his weapon, and follow the new marker to find Zakhar.

During the conversation with the man, show him his comrade's weapon, then escort him to the stash, for which you will receive 3374 coupons.

Note: If you kill Zakhar immediately after receiving the reward, you can return to the bar (a new marker will appear), talk to David, and receive another 3374 coupons.
