After exiting the Lesser Zone, your journey continues into the challenging Garbage area. Due to the distance from your starting base, encountering traders in this region takes time.
Upon completion, the game will guide you to the Slag Heap, situated north of the laboratory. However, feel free to explore this area earlier. The Slag Heap houses two valuable traders.
Boozer, located conveniently near the entrance, runs a bar selling food and drinks. He also accepts a wide variety of items for trade.
Huron, accessible by heading left and entering the open door on your right, specializes in weapons and gear. His room also serves as your stash, a safe place to store extra items. Interacting with Huron also initiates a side quest.
While not a trader, a Tech resides at the back of the left corridor within the Slag Heap. You'll encounter him while progressing the main quest, interacting with Diode.
