Although Arc Raiders have some of the hardest tasks saved for the end game, a very few of them are much easier than expected. One of the simple late-game quests is the ‘What We Left Behind’ quest. The objective is to find rare loot in some specific locations in different maps. In this guide, learn where to find significant loot and complete Arc Raiders ‘What We Left Behind’ quest.
How to Complete ‘What We Left Behind’ Quest in Arc Raiders
Before you start the mission, make sure you have some decent mobility points added to your Arc Raiders skill tree for faster extraction. Here are the objectives for the What We Left Behind quest in Arc Raiders and how to complete them:
1. Search Epic Loot in South Swamp Outpost
The first objective asks players to find a significant loot in the Dam Battlegrounds map. Once on the map, go to the South Swamp Outpost and look for valuable Arc Raiders loot. This area swarms with ARC enemies, which makes it easy to find some higher rarity items. If you don’t find anything significant, extract from the nearest Swamp Elevator and visit the location again.

2. Search Two Containers in Raider Camp
For the second objective in the quest, players must visit the Buried City map in Arc Raiders. When in the map, look for the Parking Garage, located north of the Space Travel building. Now, breach the door in the garage and enter the facility. Once you take the zipline to the bottom, loot any two containers from the Raider Camp and complete the task. The parking garage is always swarming with enemies, so keep some healing items in your bag.
3. Search Epic Loot in Bilguun’s Hideout
For the third objective, players must go to the Spaceport map. Once there, find Bilguun’s Hideout near the Container Storage area. Search this spot and find any significant loot to complete the quest. If the task does not count an item as a high-rarity loot, extract, and revisit.
