The demand for Surveyor Vault in ARC Raiders has gone up ever since the first Expedition project kicked off on Dec. 22, and you’re going to need plenty of them.
The Surveyor Vault is required as an upgrade material for the Medical Lab. While you might have kept all your upgrades intact, you’ll still have to build them with the correct resources. This guide will help you find the best spots possible to find this specific item.
Best locations to find Surveyor Vault in ARC Raiders
The only known way to find a Surveyor Vault is by taking down Surveyors. You’ll find the Surveyor on every map. My favorite locations are Dam Battlegrounds, Buried City, and Stella Montis. The Surveyor will only attack if it becomes aware of your presence. You’ll need to wait for it to become stationary since its core will then be exposed.
It’s pretty easy to take down a Surveyor when its core is exposed. However, you’ll want to do so from a distance, as it can alert your position to nearby ARCs. You can also use one of your teammates to bait it out while you can shoot at its core. Try to carry heavy weapons as they’re ideal to shred the armor of the Surveyor.

The Dam Battlegrounds appear to have the most spots when it comes to Surveyor spawns. I have marked a few of the locations where I have found them. You can try out the Ruby Residence, as this specific spot also spawns plenty of keys.
The Lobby area on Stella Montis is another great spot to come across different Surveyors (but their spawn rates will vary across raids). You can also possibly find them at the Medical Research and Assembly Workshop areas.

You can also find them on Buried City, Spaceport, and Blue Gate, but these maps can be harder to survive. Additionally, you can also find Surveyor Vault from ARC Couriers. However, it’s not guaranteed, and ARC Couriers spawn randomly on the maps. Hence, it’s best not to rely on this method.
