ARC Raiders What We Left Behind Mission Walkthrough
The tactical extraction shooter ARC Raiders challenges players with numerous multi-region objectives that test survival skills and geographical knowledge. The What We Left Behind mission stands out as a critical early milestone issued by Tian Wen that forces players to navigate three distinct environments. Completing this assignment successfully expands your regional familiarity while yielding vital weapon upgrades without demanding intense combat confrontations.
Navigating the Buried City Parking Garage
Your multi-map scavenging journey begins in the war-torn streets of the Buried City. Players must head directly to the centrally located Parking Garage near Marano Park to track down the initial caches. Because this zone frequently draws hostile ARC patrols, maintaining a low profile while approaching the structure remains highly recommended.
Once inside the Parking Garage, locate the breach door positioned in the southwest corner to unlock the lower levels. Descending the interior zipline brings you to a sand-swept subterranean chamber containing the required Raider supplies. Searching the large item case and the hidden backpack behind the corrugated metal panels satisfies the first phase of the objective.
Scouting the Dam Battlegrounds Outpost
The second phase of the quest shifts the tracking operations over to the heavily forested Dam Battlegrounds map area. Your main objective here involves investigating the South Swamp Outpost, which sits quietly on the western edge near Water Treatment Control. The dense surrounding treeline provides excellent natural camouflage against scanning drones, making this a relatively secure environment.
Move carefully into the clearing and enter the largest cylindrical building occupying the center of the outpost. Scan the interior surfaces to locate a small table positioned to the right of a prominent red storage cabinet. Interacting with the yellow-marked documents resting on this table completes the regional intelligence gathering requirement.
Reaching Bilguun Hideout at the Spaceport
The final and most vertical portion of the assignment takes place within the industrial complexes of the Spaceport. Players must navigate toward the Container Storage sector to track down a highly elusive camp known as Bilguun's Hideout. This particular structure trips up many rookies because it sits high above the ground level rather than inside the standard warehouses.
Locate the massive concrete border wall situated directly east of the primary storage yard structures. Look for the broken sections along the wall or locate the yellow ladder leading upward to scale the defensive perimeter. Once you reach the metal habitation hanging over the side, collect the marked notes inside to conclude your fieldwork.
Claiming Your Weapon Modification Rewards
With all three locations fully searched, players can safely head toward the nearest extraction point to return home. Navigating back to the safety of Speranza allows you to report your field findings directly to Tian Wen. Handing over the gathered data completes the contract and immediately upgrades your standing with the local traders.
Finishing this tracking assignment rewards your character with an impressive bundle of high-grade firearm components. Guardians receive a Tier II Muzzle Brake, a Tier II Vertical Grip, and a Stable Stock II to enhance weapon performance. These tools significantly improve weapon stability during high-stakes raids, ensuring you are better prepared for subsequent survival runs.
