After exiting the Lesser Zone, your journey continues into the sprawling Garbage area. Due to its distance from your starting base, encountering traders will take some time.
Upon completion, the game will guide you to the Slag Heap (north of the laboratory). However, feel free to explore it earlier. The Slag Heap features two valuable traders:
Boozer: Located at the entrance, Boozer runs the bar, selling food and drinks while accepting a wide variety of trade goods. He's hard to miss.
Huron: Found by heading left and entering the open door on your right, Huron specializes in weapons and equipment. His room also serves as your stash, allowing you to store extra items. Speaking with him also initiates a side quest.
While not a trader, a Tech is located at the back of the left corridor. You'll need to interact with him (Diode) to advance the main quest.
Stalker 2: Heart of Chornobyl is available now on Xbox and PC.
