You only went to the dump from Cordon, your task to help Besu to facilitate the destruction of bandits, do not take the task of helping at the demon, and come to the bandits (they will not shoot you) and throw a grenade. On the same territory of the Cemetery of Technology, go (jump) in KAMAZ, in the box you will find the first silencer.
At “Agroprom”, come to the radioactive lake, where the single soldier hides (the only neutral of the military) and ask him. In this lake, if you enhance it well, you will find the artifact “Battery” of the electric shock +30. In the tunnel of the railway lies the artifact “Golden Fish”.
