What We Left Behind Quest Guide in Arc Raiders

What We Left Behind is a longer, story-focused quest in ARC Raiders that sends you across multiple surface zones instead of keeping you locked to a single map. The mission is handed out by Tian Wen and unfolds in stages, with each step tied to a different location and a specific interaction you need to complete during live raids. Because of this, it plays very differently from standard contracts and rewards players who plan their routes and extractions carefully. In this guide, you’ll find a clear breakdown of every step in the What We Left Behind quest, including which maps you need to deploy on, what objects or areas you must interact with to progress, and what you receive once the quest is fully completed.

What We Left Behind Quest Requirements

To complete What We Left Behind, you’ll need to deploy into three separate maps and interact with specific points of interest on each one. First, on Buried City, head to the Raider Camp located underneath the Parking Garage and loot two separate containers inside the area. Next, queue into Dam Battlegrounds and make your way to the South Swamp Outpost, where you’ll need to inspect an object tied to the quest to move forward. Finally, travel to Spaceport and locate Bilgunn’s Hideout near the Container Storage section, then interact with a significant item there to finish the last step. Each objective is simple once you’re in the right place, but knowing exactly where to go helps you avoid wasted time, unnecessary fights, and risky rotations during the raid.

1. Buried City

The quest begins on Buried City. Make your way to the Parking Garage and look for a secured entrance that looks similar to an elevator door. Break it open to reach the underground section of the area. From there, continue down until you reach the lowest level, where the Raider Camp is located. Inside the camp, you’ll need to search and loot two separate containers to complete this step. Once both containers have been opened, the objective will update, and you’re free to extract or move on to the next map for the following part of the quest.

2. Dam Battlegrounds

For the second step, head to Dam Battlegrounds and make your way toward the South Swamp Outpost on the western side of the map. Enter the outpost building and search the interior until you find a set of documents or files that can be interacted with. Examine them to complete this objective. After that interaction is registered, this part of the quest is finished, and you can leave the area and prepare for the final location.

3. Spaceport

For the last step, load into the Spaceport map and head toward the Container Storage area. Along the wall behind it, you’ll find a small depot-like structure known as Bilgunn’s Hideout. Go inside and look around the floor for scattered notes or documents. Interact with them to complete the final objective. Once this interaction is done, the quest concludes and your rewards are granted automatically.

Quest Rewards

Once you’ve finished every objective on all three maps, head back to Tian Wen to turn the quest in. Completing What We Left Behind rewards you with three weapon attachments: Muzzle Brake II, Vertical Grip II, and Stable Stock II. Together, these upgrades noticeably improve recoil control, stability, and overall weapon handling, making them solid additions to your loadout for future raids.

Conclusion

What We Left Behind is a great example of how ARC Raiders encourages exploration across multiple maps rather than locking progress to a single raid. By knowing exactly where to go on Buried City, Dam Battlegrounds, and Spaceport, you can complete the quest efficiently without wasting time or taking unnecessary risks. The objectives are simple, but planning your routes and extracting safely after each step makes the process much smoother. Once finished, the weapon attachments you earn are solid upgrades that benefit most loadouts, making this quest well worth completing early as you progress through ARC Raiders.
