This comprehensive guide details the completion of the 'What We Left Behind' quest in Arc Raiders, which involves locating hidden Raider Camps across various regions to gather vital salvage for the character Tian Wen. The mission can be challenging due to the elusive nature of some camp locations. This walkthrough provides clear instructions to navigate each area and successfully retrieve the necessary items, ensuring players can progress efficiently through this intricate task.

The 'What We Left Behind' mission in Arc Raiders presents a significant challenge, requiring players to meticulously search for concealed Raider Camps. These camps, scattered across diverse environments, hold crucial salvage sought by Tian Wen, a character known for her expertise in weaponry. While one of the camps might be easily discovered, others are considerably more difficult to pinpoint, necessitating a precise and detailed approach. This guide breaks down the mission into manageable steps, focusing on three primary locations: Buried City, Dam Battlegrounds, and Spaceport. Each section offers specific directions and contextual details, helping players to overcome potential frustrations and successfully complete their objectives. By following these instructions, players can efficiently gather all required items and advance in their Arc Raiders adventure, contributing to Tian Wen's inventory and overall game progression.

Navigating Raider Camps in Buried City and Dam Battlegrounds

In the Buried City, players must locate two containers within a Raider Camp situated beneath the Parking Garage. This area, known for frequent encounters with Arc enemies, demands a cautious approach. Upon entering the Parking Garage, players should find a breachable door in the southwest corner, leading to a zipline. This zipline descends to a sand-filled room, where the two salvage containers—a long case and a bag behind corrugated metal—are found amidst a makeshift settlement. Moving to the Dam Battlegrounds, the task simplifies: head to the South Swamp Outpost, near Water Treatment Control, and search the main cylindrical building for documents marked with a yellow search icon on a table.

To successfully navigate the initial stages of the 'What We Left Behind' mission, players begin their search in the Buried City. The primary objective here is to secure two specific containers hidden within a Raider Camp. This camp is strategically located beneath the Parking Garage, adjacent to Marano Park, which is known for its intense Arc activity. Therefore, discretion and readiness for combat are advised. Upon infiltration of the Parking Garage, look for a distinctive breachable entrance in the southwestern sector. This passage leads to a zipline, providing access to a lower level that is largely submerged in sand. Within this subterranean space, an improvised living area hosts the two target containers: a lengthy case and a fabric bag concealed behind some corrugated metal. Following this, the mission directs players to the Dam Battlegrounds. This part of the quest is less complex; players need to make their way to the South Swamp Outpost, found in the western part of the Dam Battlegrounds, close to the Water Treatment Control facility. Inside the central cylindrical structure of this outpost, a table bearing important documents, highlighted by a prominent yellow search marker, awaits discovery.

Uncovering Bilguun's Hideout in Spaceport

The most challenging part of the mission involves locating Bilguun's Hideout in Spaceport. This hideout is not on ground level but atop a wall east of Container Storage. Players need to find broken sections of the wall, either to the north or south, to climb up. Once on the wall, the metal Raider Camp, hanging off the side, becomes visible. Inside this camp, players will find and collect yellow-marked notes, completing this final, often elusive, objective of the quest.

The search for Bilguun's Hideout in the Spaceport district often proves to be the most perplexing segment of the entire mission. This elusive camp is not located on the conventional ground level but is ingeniously positioned on the elevated wall that runs directly east of the Container Storage area, situated centrally within the Spaceport. To gain access, players must meticulously scout along the northern or southern stretches of this wall for any compromised or broken sections that facilitate climbing. Once successfully ascended to the top of the wall, the distinct metallic structure of the Raider Camp, visibly suspended from the side, will come into view. Entry into this elevated hideout reveals a collection of yellow-marked notes. Interacting with and collecting these specific notes signifies the triumphant completion of this particularly challenging and often frustrating phase of the 'What We Left Behind' mission, bringing players closer to fulfilling Tian Wen's request.
