Bilguun’s Hideout sits on the Spaceport map, next to the Container Storage area. Head into that cluster of stacked freight and yard structures and sweep the hideout for any epic-rarity (“significant”) loot. Picking up a qualifying item completes the Spaceport leg of the quest.

If the game doesn’t register the pickup, extract and re-enter the zone, then try again. This objective can be picky about what counts, and a fresh instance often resolves it.

Complete the other objectives (quest order)

The quest “What We Left Behind” spans three hotspots across different maps. Tackle them in any order, but the loop below keeps travel efficient and extraction safe.

Objective Map Where to go What to do Notes
Search epic loot in South Swamp Outpost Dam Battlegrounds South Swamp Outpost Find and pick up any epic-grade item to progress. If nothing qualifies, extract at the nearest Swamp Elevator and re-run.
Search two containers in Raider Camp Buried City Parking Garage north of the Space Travel building Breach the garage door, take the zipline to the bottom, and loot any two containers in the Raider Camp. Expect heavy resistance inside; carry healing items.
Search epic loot in Bilguun’s Hideout Spaceport Container Storage area Pick up any epic-grade item within the hideout to complete the step. If it doesn’t register, extract and try another instance.

What counts as “significant” loot

For this quest, “significant” means epic-rarity items. Valuable or recyclable epic items both qualify. If you’re sweeping a marked area and only finding lower tiers, cycle the instance by extracting and dropping back in until an epic spawns or an epic container roll appears.

Setup and survival checks

  • Mobility perks: Invest a few points in mobility on your skill tree to shorten extraction runs.
  • Healing and ammo: The Buried City parking garage is packed with enemies; go in topped up and with a fallback route to the exit.
  • Instance cycling: If an objective pickup fails to tick, extract and re-enter the map. This is the fastest fix.

Rewards for “What We Left Behind”

  • Muzzle Brake II
  • Vertical Grip II
  • Angled Grip II

Those parts feed clean attachment upgrades and are worth the short detours, especially once you know where each hotspot lives.

Fast route recap

Hit Dam Battlegrounds first and clear the South Swamp Outpost, extract via the closest Swamp Elevator if needed, then pivot to Buried City’s parking garage north of Space Travel to loot two camp containers. Finish in Spaceport at the Container Storage cluster—Bilguun’s Hideout—snag an epic item, and extract. If any step fails to log, cycle the zone and repeat the sweep. With this route and a little instance luck, the quest typically falls in a couple of runs.
