Difficulty level: Hard
Reward: 3000 Exp, Shark Mod
Carter is in one of the huts in the village (1) #1. Once you get inside you'll see him mourning his murdered wife. He will ask you to avenge him by killing Vargass, Afran's gang member. It is the best to take a car to go to the destination - you can find one right outside the village (2) #2.
After reaching the place (3) prepare you firearms because you'll have a small shooting. You can shoot at the gas tank near the station building #1, another one is located on the roof. Before you go inside, you might walk to the other side of the building. There is one unsecured window #2 there - you'll be able to take down two soldiers.
Break the door into the broadcasting station and go inside. Vargass hides behind lockers #1 - you can throw a Molotov or a grenade there - he can't escape. Once he is dead return to Carter (1) #2 and tell him that you killed the murderer.
