Tian Wen’s weapon shop sends you on a three-part quest across various areas in ARC Raiders to collect items once again. Of course, the locations won’t be marked on your map, so we’ll show you where to go to complete the quest.
What is this quest about? The weapons dealer Tian Wen will eventually send you on the quest “What We Left Behind.” In this quest, you need to visit three maps, loot items, and gather information.
As usual, there’s no quest location marked in ARC Raiders, so you’ll have to search for the locations yourself. That’s why we visited all three locations to show you where they are.
Dam Battlefields: Find Something of Importance
In the dam battlefields, you need to find “something of importance” in the swamp area. For this, Tian Wen sends you to the southern swamp outpost, which is located west of the water treatment control room.
Go into the swamp and look for a building that looks like a rundown silo – go inside. On one of the shelves, you will find some documents that you need to interact with. Once you’ve done that, this part is complete.



Buried City: Find 2 Containers under the Parking Garage
In the buried city, you now need to head to the parking garage, which is located near the hospital. Go to the lowest floor and look for a sealed door with the sign “1” – break it open.
Go through the door and use the zip line to reach the lowest floor. Once you arrive, you need to search 2 containers of your choice. These include hoods from vehicles, weapon cases, bags, metal boxes, and much more. Once you’ve searched 2 containers, you’re done here as well.



Spaceport: Find Bilguun’s Hideout
The probably hardest part is finding Bilguun’s hideout. It is located on the outer wall of the container storage in the spaceport. Visit the east side of the storage and look for a ladder. Climb up and search southeast for a small book that is on a pile of clothes. On our pictures, you can see the exact locations.



What rewards are there for the quest? Once you have completed the quest, you will receive three level 2 upgrades:
- a muzzle
- a grip
- a stock for your rifles.
The rewards are a nice bonus, but not high-end components for your builds.
Those were all the important details for the quest “What We Left Behind.” Did you have any trouble finding Bilguun’s hideout? Some players have also struggled with the Major’s box alongside this quest, as it seems to be bugged. We’ll show you how to possibly fix this problem in our guide: ARC Raiders: Major’s Footlocker – How to solve the quest (also with a bug)
