In the What We Left Behind quest in ARC Raiders, you will be sent to three different maps to uncover valuable loot. The objectives are straightforward, but they may require some patience. Follow along with this guide for a walkthrough on each mission objective so you can complete it easily and efficiently.
Loot at the Dam
Your first stop is the Dam Battlegrounds Map, at the South Swarm Outpost. You should head to the area and start looting any of the containers inside and around the building until it completes the objective.

If your progress doesn’t count the first time, you may have to restart the run and try again. Sometimes the quest tracker just needs a refresh to recognize your loot.

Bilguun’s Hideout
Next, move over to the Spaceport map and head toward Bilguun’s Hideout, which is located right next to Container Storage. You’ll need to climb the ladder up to the top section where the hideout sits. Once inside, loot any of the containers here.

Again, if the quest doesn’t update, repeat the process. This can be frustrating, but the game may have issues recognizing your loot.

Raider Camp
For the final objective, you will need to play on the Buried City map. You’ll need to search two cars in the bottom of the Parking Garage. Try to start by looting the vehicles in the area, but work your way up if the quest hasn’t counted yet. If nothing still doesn’t count, follow the route toward the underground Raider Camp and loot throughout there.

Once you loot the correct containers (the game can be picky), this will complete your final objective and complete your quest.

And that is all there is for the What We Left Behind quest in ARC Raiders! The mission may seem tedious, but it gets you exploring different maps and locations, gathering new loot, and increasing your route knowledge. Sounds like a win-win to me!
