On the location of the “Dark Valley” you can get the SCU (something like SVD, weighs less, and the other characteristics are almost like in SVD. To do this, we need to climb the radioactive part of the base of freedom to the second floor or the roof, I don’t remember exactly, then you will see the leader of the freedom in the window on the opposite. Flashki needed. Attention !!! It is necessary to shoot it only after the quest line is fulfilled, and after his murder, it is impossible to enter freedom, t.to. only he takes a grouping!!!
