Overview
- The quest continues the contamination investigation by sending players back to the drain below the Water Treatment Control on the Dam Battlegrounds map.
- Players trace the barrel to a half‑submerged truck in the swamp, take a photo of it, then search the cab for clues.
- Searching the truck spawns a Spaceport Warehouse Key that is not required to complete the quest but can be used later on the Spaceport map.
- Because items can be lost on death, guides recommend stowing the key in a safe pocket or extracting at the nearby Central Swamp Lift to secure it.
- The quest arrived with the Cold Snap update, unlocks The Stench of Corruption toward the Warden outfit, and sits near Candleberry spawns for the time‑limited Flickering Flames project.
