ARC Raiders Surveyor Vaults: Locations & Loot Guide
Quick Takeaways
- The Core Objective: Surveyor Vaults are highly fortified, sealed underground bunkers containing tier-four weapon blueprints and rare pristine materials.
- Access Requirements: Opening a vault requires a Surveyor Decryption Key and a sustained ninety-second terminal hack.
- High-Risk Defense: Initiating the hack triggers a localized security lockdown, spawning aggressive ARC defensive units and alerting nearby rival Raiders.
- Top Locations: The three primary vaults are situated at the Sunken Outpost, Sector Bravo Depot, and the Ridge Line Bunker.
Complete Overview & Search Intent
In the harsh, mechanized wasteland of ARC Raiders, survival demands more than quick reflexes—it requires superior technology. For Raiders looking to transition from basic survival gear to endgame weapon systems, finding and successfully looting a Surveyor Vault is the ultimate milestone. These subterranean bunkers, remnants of pre-collapse automated research operations, contain the most coveted loot caches on the map.
However, getting inside a Surveyor Vault is not as simple as stumbling upon a door and pressing an interaction prompt. These vaults are locked behind multi-layered security protocols, heavily guarded by automated ARC systems, and frequently monitored by rival squads looking for an easy ambush. This guide provides the exact coordinates, entry requirements, defense strategies, and extraction routes needed to secure this high-tier loot and make it back to the Sperry settlement in one piece.
Deep Dive Mechanics & Technical Specs
To successfully raid a Surveyor Vault, you must first understand the technical loop governing these high-tier loot zones. Vaults do not remain open; they are permanently sealed at the start of each match and require active player intervention to unlock.
The Surveyor Decryption Key
Before heading to a vault entrance, your squad must secure a Surveyor Decryption Key. These keys are high-grade electronic items that drop exclusively from elite ARC patrol leaders or can be found rarely inside heavy industrial crates in high-threat sectors.
- Drop Probability: Elite ARC Patrol Units (15% drop rate), Heavy Industrial Crates (5% spawn rate).
- Inventory Footprint: Takes up a 2x1 slot in your inventory. If you are eliminated before reaching the vault, the key is lost.
The Decryption Hack Sequence
Once you insert the key into the vault terminal, a ninety-second countdown begins. This sequence is loud, highly visible, and triggers several environmental shifts:
- Acoustic Signature: A heavy klaxon sounds within a two-hundred-meter radius, alerting any nearby Raiders that a vault breach is in progress.
- Security Response: The automated vault defense system deploys waves of ARC units directly to your position. These are not standard roaming units; they are specialized security models programmed to target the terminal and your squad.
- Interruption Mechanic: If an ARC machine or an enemy player interacts with the terminal during the countdown, the hack pauses, extending the time you must defend the choke points.

Step-by-Step Tactical Walkthrough
Successfully executing a Surveyor Vault run requires precise coordination. Split your run into five distinct operational phases.
Phase One: The Pre-Drop Loadout
Do not attempt a vault run with budget gear. Your squad needs a balanced mix of crowd control, high burst damage, and defensive utility.
- Weapons: At least one squad member should carry a high-impact kinetic rifle for armor stripping. Another should run an energy-based weapon to quickly melt ARC shields.
- Gadgets: Bring EMP Grenades to temporarily disable incoming security waves. Deployable Decoys are also highly effective at redirecting ARC aggro away from the hacking terminal.
Phase Two: Securing the Access Key
Avoid wandering aimlessly looking for a key. Drop into zones adjacent to the vaults that feature high concentrations of industrial containers. Search these areas quickly. If an elite ARC patrol spawns nearby, coordinate a silent takedown using suppressed weapons to avoid drawing the attention of other players early in the match.
Phase Three: Approaching the Vault Perimeter
When approaching any of the three vault locations, do not rush straight to the terminal. Assume another squad is already watching the entrance.
- Establish a perimeter watch.
- Send your scout to check high-angle overlooks.
- Verify that the terminal has not already been accessed or tampered with.
- Clear out any local roaming ARC units before inserting the key.
Phase Four: Defending the Terminal
Once the key is inserted, the ninety-second defense phase begins. Do not cluster around the console. Instead, establish a triangular defensive posture covering the main entry points.
Use EMP grenades on the first wave of fast-moving drones to prevent them from interrupting the hack. Save your heavy munitions for the second wave, which typically includes armored bipedal ARC units. Keep one player dedicated to monitoring the terminal's status and scanning the rear flanks for opportunistic player squads.
Phase Five: Looting and Clean Extraction
When the countdown hits zero, the vault doors will hiss open. Inside, you will find three high-tier storage lockers.
- Prioritize Blueprints: Grab the weapon schematics first; these are secured to your progression once extracted.
- Quick Inventory Sort: Do not linger inside the vault. Grab the loot, distribute the weight among your squadmates, and immediately head for the nearest extraction point. The longer you stay near a freshly opened vault, the higher the likelihood of running into an extraction-camping squad.
Map Locations & Threat Mitigation
The Sunken Outpost Vault
Located in the southern lowlands, this vault is partially buried under mud and concrete debris. It is the most accessible vault for solo players or under-geared squads, but its low-lying position makes it vulnerable to long-range sniper fire from the surrounding ridges.
- Tactical Approach: Approach from the western drainage tunnels. This allows you to enter the vault area without crossing the open mudflats.
- Defensive Strategy: Use the concrete pillars surrounding the terminal for cover. Place a deployable shield facing the northern ridge to block incoming sniper fire while defending the hack.
Sector Bravo Depot Vault
Situated in the heart of an abandoned industrial manufacturing complex, this vault is surrounded by multi-story warehouses and catwalks. The verticality of this zone makes it incredibly dangerous.
- Tactical Approach: Access the depot via the underground utility corridors. Avoid the main roads, which are heavily patrolled by high-tier ARC units.
- Defensive Strategy: Assign one squad member to hold the high catwalk directly above the terminal. From this vantage point, they can rain down fire on incoming security units and spot hostile Raiders attempting to push your position.
The Ridge Line Bunker Vault
Perched high in the snowy northern cliffs, this is the most difficult vault to crack. It requires two Decryption Keys inserted simultaneously into dual terminals, making it a challenge designed specifically for coordinated three-player squads.
- Tactical Approach: Climb the eastern mountain trails to bypass the heavily guarded valley floor.
- Defensive Strategy: Because you must defend two terminals separated by thirty meters, split your squad into a two-one configuration. Use high-damage claymores or proximity mines to secure the blind approaches while your squad focuses fire on the main valley path.
Pro Survival Tips & Stash Strategy
- The Decoy Hack: If you suspect an enemy squad is stalking you, insert a key and immediately retreat to a hidden vantage point. Let the enemy push the terminal to stop the hack, then ambush them while they are distracted by the incoming ARC security waves.
- Inventory Management: Before opening the vault, discard low-value materials like scrap metal or common wiring. You need every available inventory slot for the pristine composites and weapon frames found inside the vault lockers.
- Extract with Discretion: Never head for the closest extraction point if it lies in a wide-open area. Travel an extra two hundred meters to a forested or industrial extraction zone where you have ample cover to defend against exit campers.
Frequently Asked Questions (FAQ)
Can I open a Surveyor Vault without a Decryption Key?
No. The physical vault doors are completely invulnerable to standard explosives, kinetic weapons, and energy tools. The only way to initiate the opening sequence is by inserting a valid Surveyor Decryption Key into the primary terminal.
Do Surveyor Vault keys persist in my inventory if I die?
No. Decryption Keys are active raid items. If you are eliminated while carrying a key in your backpack, it will drop on your player crate, allowing other Raiders or your teammates to loot it.
Can a solo player successfully complete a vault run?
While possible, it is exceptionally difficult. The security waves that spawn during the hacking phase are tuned for group encounters. Solo players should focus on the Sunken Outpost Vault, utilizing heavy crowd-control gadgets like EMP mines and decoys to manage the ARC units.
How many times can a single vault be looted per match?
Each vault can only be unlocked and looted once per match. Once the doors are opened and the lockers are cleared, the terminal becomes inactive for the remainder of the session.
Final Verdict & Raider Checklist
Before heading out on your next drop to hunt down a Surveyor Vault, run through this operational checklist to ensure your squad is fully prepared for the trial ahead:
- Key Acquisition Plan: Do you know which industrial sectors you are looting first to secure your Decryption Key?
- Balanced Loadout: Does your squad have a mix of armor-stripping kinetic weapons and shield-melting energy firearms?
- Crowd Control Preparedness: Is everyone carrying at least one EMP grenade or decoy to manage security waves?
- Designated Roles: Have you decided who will monitor the terminal and who will hold the primary defensive lanes?
- Extraction Route Planned: Have you identified two backup extraction zones in case your primary exit is camped?
