Navigating the post-apocalyptic landscapes in ARC Raiders requires a blend of tactical awareness, map knowledge, and efficient scavenging. The What We Left Behind quest assigned by Tian Wen pushes players to explore three separate regions to locate key raider camps and lost supplies. Understanding how to clear each objective safely ensures steady progression without taking unnecessary combat risks.
Searching the Buried City Raider Camp
The initial objective takes place in the Buried City, where you must locate a hidden raider camp situated beneath the central Parking Garage. Enter through the southwest breach door and descend the zipline into the underground structure to find two key containers. Be cautious of high enemy patrols around nearby landmarks, and focus on looting quickly before extracting.
Exploring the South Swamp Outpost in Dam Battlegrounds
Your second destination leads to the Dam Battlegrounds to investigate the South Swamp Outpost located west of Water Treatment Control. The dense forest surrounding the area provides excellent environmental cover against scouting ARC units. Head inside the central cylindrical structure and interact with the marked documents resting on the table.
Uncovering Bilguun's Hideout at Spaceport
The final task demands exploring the Spaceport region to find Bilguun's Hideout positioned near Container Storage. Scale the wall on the eastern border using broken sections and climb the ladder to reach the suspended raider dwelling. Collect the notes on the floor inside the habitation module to fulfill the remaining quest requirement.
Quest Completion and Recommended Loadout Tips
Since this scavenger mission does not require extracting specific inventory items, players can complete objectives across multiple raids using basic gear. Returning to Speranza after visiting all three sites unlocks valuable weapon attachments including muzzle brakes and grips. Using stealth techniques and keeping a mobile playstyle ensures smooth completion across all map locations.
