Quest Guide: What We Left Behind

Multi-map walkthrough for What We Left Behind with objectives, prep, route order, and extract notes.

What We Left Behind is a quest run in ARC Raiders. This version is written as a practical raid plan: what to bring, the order to run the steps in, and what usually kills the run once the quest is technically done.

Objective list

  • On Buried City, search 2 containers in the Raider Camp beneath the Parking Garage
  • On Dam Battlegrounds, search for anything significant in the South Swamp Outpost
  • On Spaceport, search for anything significant in Bilguun's Hideout, next to the Container Storage

What to bring

  • A reliable mid-range primary and a sidearm or close-range backup; most quest deaths happen while rotating, not while looting.
  • Stamina-friendly utility like smoke or a distraction item, because recon steps usually force you into exposed rooftops, offices, or dead-end rooms.
  • Enough meds and shields to survive two rotations; multi-location quests punish players who arrive at the final step with no resources left.

How to run it

This is a multi-map quest. Unless your quest log explicitly says everything must happen in one round, treat each map as its own clean deployment. Finish one location, extract, restock, then queue the next leg instead of forcing the whole chain in one stressed run.

  1. Step 1: On Buried City, search 2 containers in the Raider Camp beneath the Parking Garage

    Treat this as a hard objective, not a side stop. Finish the interaction, confirm the quest tracker updates, then rotate before the next squad arrives.

  2. Step 2: On Dam Battlegrounds, search for anything significant in the South Swamp Outpost

    Treat this as a hard objective, not a side stop. Finish the interaction, confirm the quest tracker updates, then rotate before the next squad arrives.

  3. Step 3: On Spaceport, search for anything significant in Bilguun's Hideout, next to the Container Storage

    Treat this as a hard objective, not a side stop. Finish the interaction, confirm the quest tracker updates, then rotate before the next squad arrives.

Where players usually throw this quest

  • Running past the actual interaction prompt. Slow down for five seconds, clear the room, and let the tracker update before leaving.
  • Taking a fight on the way out just because you hear it. Quest raids are won by discipline, not by K/D.

Miswired note

If you queue this with friends, split jobs by map familiarity: let one person lead each location and keep the others on security and callouts.
