You can get Surveyor Vaults in ARC Raiders by either destroying Surveyors (the big blue‑beam machines) or looting ARC Couriers , though the former is the most reliable method.

Where Surveyor Vaults Drop

  • From Surveyors :
    Surveyor Vaults are scavenged from destroyed Surveyors , which appear on most maps as tall machines firing a blue beam into the sky.
* Surveyors only attack once they “see” you, and their weak‑core is exposed when they stop moving.

* Use heavy weapons from a distance and try to have a teammate bait them while you shoot the core.
  • From ARC Couriers :
    Surveyor Vaults can also drop from ARC Couriers (marked on your map as smoke icons), but this is not guaranteed and should be treated as a bonus, not your main farming route.

Best Maps & Spots to Farm

Here are the most commonly recommended maps and zones to find Surveyors and Surveyor Vaults:

Map / Area| Why it’s good
---|---
Dam Battlegrounds| High Surveyor spawn density; popular farming spots include Ruby Residence and nearby high‑ground areas. 15
Buried City| Good open sightlines and frequent Surveyor spawns; many players farm here solo. 156
Stella Montis| Lobby‑side areas, Medical Research , and Assembly Workshop often spawn Surveyors. 1
Blue Gate| Surveyors frequently appear around the northwestern village , which tends to be less crowded. 35
Spaceport / Blue Gate (Night Raids / Storms)| Event‑style raids can also spawn Surveyors and Couriers, but extraction is trickier since raider hatches may be inactive. 4

Quick Farming Tips

  • Look for the blue beam : Open your map and watch for the tall blue beam in the sky; that’s the Surveyor’s current position.
  • High‑ground advantage : Get on elevated terrain (rooftops, hills) so you can see the beam and line up shots on the core.
  • Run event‑style raids : Electromagnetic storms, night raids, and hidden‑bunker‑type events can increase chances to encounter Surveyors or Couriers, but be mindful of extraction rules.

If you tell me which map you play most (e.g., Buried City vs. Dam Battlegrounds), I can sketch a simple route‑style loop to maximize Surveyor encounters and Surveyor Vault drops.
