Arc Raiders ‘What We Left Behind’ Quest Guide

TL;DR

  • Complete three loot collection objectives across Dam Battlegrounds, Buried City, and Spaceport maps
  • Utilize strategic extraction and re-entry when loot doesn’t register properly
  • Prepare for heavy enemy resistance with proper healing and mobility skills
  • Earn valuable weapon attachment upgrades including Muzzle Brake II and grip attachments
  • Master location-specific tactics to minimize completion time and maximize efficiency

While Arc Raiders presents numerous challenging endgame activities, the ‘What We Left Behind’ mission stands out as one of the more accessible late-game objectives. This scavenger hunt-style quest requires locating valuable equipment caches across three distinct combat zones. Understanding the core mechanics and preparing adequately will significantly enhance your success rate.

Before initiating this operation, ensure you’ve allocated sufficient mobility enhancements within your Arc Raiders skill progression system. Enhanced movement capabilities facilitate quicker extraction when missions require rapid disengagement. Consider investing in dash upgrades and stamina regeneration to navigate hostile environments more effectively.

Common Preparation Mistakes: Many players underestimate the enemy density in target areas and arrive with insufficient healing items. Always carry at least three medical kits and consider bringing distraction devices to create escape opportunities when overwhelmed by ARC forces.

Your initial objective directs you to the Dam Battlegrounds territory, specifically targeting the South Swamp Outpost sector. This region typically contains concentrated ARC patrols, which paradoxically increases your chances of discovering superior rarity equipment. The heightened enemy activity often correlates with better loot spawn rates, making the combat risk worthwhile for determined Raiders.

Navigation Strategy: Upon reaching the map, proceed directly to the southern swamp sector. The outpost is recognizable by its elevated structures and damaged industrial equipment. Approach cautiously, as ARC units frequently patrol in coordinated patterns that can quickly overwhelm isolated players.

If your initial search fails to yield appropriate high-value items, employ the extraction reset method. Withdraw via the nearest Swamp Elevator extraction point, then immediately redeploy to refresh the loot tables. This technique typically requires 2-3 attempts before registering completion.

Advanced Tactical Insight: Seasoned players recommend engaging enemies from elevated positions around the outpost before looting. Clearing nearby hostiles first reduces the risk of interruption during the collection process and may slightly improve loot quality through the game’s dynamic difficulty scaling.

The second phase transports you to the urban decay of Buried City, targeting the multi-level Parking Garage complex situated north of the Space Travel architectural landmark. This location presents unique challenges due to its confined spaces and limited escape routes, demanding careful tactical planning.

Access Protocol: Breach the reinforced entrance door using your standard equipment, then descend via the internal zipline system to reach the subterranean Raider Camp. This lower level contains multiple storage containers, from which you must secure loot from any two to fulfill the objective requirement.

The garage interior maintains consistent enemy presence, with patrols rotating between levels. Always maintain awareness of your positioning relative to extraction points. For optimal results, consider coordinating with squad members to cover different entry points while looting.

Combat Preparation: Given the predictable heavy resistance, equip yourself with area-denial tools and rapid-healing items. The confined environment favors close-quarters weaponry, though bringing a versatile mid-range firearm provides flexibility when engaging from the garage’s upper levels before descending.

Your final destination lies within the Spaceport operational zone, specifically targeting Bilguun’s Hideout adjacent to the Container Storage sector. This location typically features less concentrated enemy presence than previous objectives, though remaining vigilant is still essential.

Location Identification: The hideout is situated near the western perimeter of the container storage area, recognizable by its makeshift barricades and accumulated salvage materials. Search the premises thoroughly for any high-value equipment that meets the quest’s rarity threshold.

Should the game fail to recognize your collected items as qualifying loot, repeat the extraction reset procedure used in previous locations. This consistency in troubleshooting methodology across all three objectives streamlines the completion process.

Verification Technique: Before extracting, open your inventory to confirm item rarity meets requirements. Some players mistakenly collect adequate loot but extract prematurely without proper verification, necessitating unnecessary repetition.

Upon successful completion of all three loot retrieval operations, you’ll receive substantial advancement resources, particularly focusing on weapon modification systems. These components significantly enhance your combat effectiveness in subsequent endgame activities.

Primary Reward Analysis: The quest grants three specialized attachment upgrades: Muzzle Brake II for improved recoil control, Vertical Grip II enhancing aiming stability, and Angled Grip II optimizing movement while aiming. Each attachment provides tangible benefits that complement various playstyles and weapon configurations.

The Muzzle Brake II specifically reduces vertical recoil by approximately 15%, making it invaluable for automatic weapons. The grip attachments offer between 8-12% improvement in their respective specialized areas, allowing for more precise customization of your preferred firearms.

Progression Impact: These mid-tier attachments serve as crucial stepping stones toward unlocking superior modifications. They’re particularly valuable for players transitioning into advanced content where weapon performance becomes increasingly critical.
