MMOexp ARC Raiders: Investigate the South Swamp Outpost
Posted: Sun Jan 25, 2026 10:09 pm
If you're still getting familiar with the maps, this quest can feel a little overwhelming at first. The objectives are deliberately vague, and without knowing exactly where to ARC Raiders Coins look, you could waste a lot of time wandering around dangerous areas.
Because of that, it's perfectly safe to deploy with a free loadout if you want to avoid risking valuable gear. You're free to bring stronger equipment if you expect trouble, but it's not required to complete any part of the quest.
Below is a step-by-step breakdown of how to complete every objective in What We Left Behind as efficiently and safely as possible.
Search Two Containers in the Raider Camp Beneath the Parking Garage (Buried City)
The first objective sends you to Buried City, specifically to the Parking Garage located on the northwestern side of the map. This area is popular with looters, as abandoned vehicles often contain useful materials, so it's a good idea to stay alert for other Raiders.
Once you reach the Parking Garage, head inside and make your way to the first floor. Look for a door clearly labeled "01." This door is locked and will need to be breached to open it. Before doing so, pause for a moment and check your surroundings-breaching doors is loud and can easily attract attention.
After breaching the door, you'll find a zipline immediately behind it. Take the zipline down to reach a hidden Raider Camp beneath the garage. This lower area is compact and usually quiet, making it ideal for completing the objective quickly.
Inside the Raider Camp, simply loot any two containers. The specific containers don't matter, as long as you interact with two of them. Once that's done, the first step of the quest will be marked complete.
At this point, you can safely extract and return to Speranza, or you can continue looting if you feel confident. When you're ready, head back underground to prepare for the next stage.
Investigate the South Swamp Outpost (Dam Battlegrounds)
The second objective takes place on Dam Battlegrounds, at the South Swamp Outpost on the western side of the map. Compared to Buried City, this area tends to see less traffic, making it one of the safer locations in the game-though no place is ever completely risk-free.
As you approach the outpost, move carefully and keep an eye out for other Raiders who may be working on the same quest. Once inside, locate the large, circular main room of the building.
In this room, you'll find a stack of papers that can be interacted with. This interaction represents your investigation of "something significant" at the outpost. Activate it, and the second quest objective will immediately be completed.
There's no additional looting requirement here, so once you've interacted with the papers, you're free to extract. With two objectives down, only one final location remains.
Search Bilguun's Hideout Near Container Storage (Spaceport)
The final step of What We Left Behind takes you to Spaceport, specifically to Bilguun's Hideout. This location sits next to Container Storage, attached to a massive concrete wall that makes it easy to spot once you're in the area.
Bilguun's Hideout is rarely occupied by other players, but it's still wise to stay cautious-Spaceport is large, open, and unforgiving if you get caught off guard.
When you arrive, look upward, and you'll see the hideout positioned above ground level. A yellow ladder leads directly up to ARCR Coins it, providing easy access without any complicated traversal.
Because of that, it's perfectly safe to deploy with a free loadout if you want to avoid risking valuable gear. You're free to bring stronger equipment if you expect trouble, but it's not required to complete any part of the quest.
