Arc Probes are ground units dropped by ARC during “Prospecting Probes” events. This guide covers where to find them, how they behave, and step-by-step breach tactics to minimize danger and maximize loot.

Common ARC Probe spawn areas on each map

On every major map—Dam Battlegrounds, Acerra Spaceport, Buried City, Blue Gate, and Stella Montis—ARC occasionally deploys Prospecting Probes. While exact spawn points rotate, several locations consistently host probes:

  • Dam Battlegrounds: Hydroponic Dome Complex near the water treatment structures.
  • Acerra Spaceport: Cargo bays adjacent to the main hangar, especially around the southern elevator.
  • Buried City: Baron Husk scavenging zones in narrow alleyways and collapsed plazas.
  • Blue Gate: Around mountain pass Raider Hatches, where probe husks often appear.
  • Stella Montis: Ruined cantina rooftops overlooking the valley.

Listen for the characteristic pinging to zero in on a probe. Once in proximity, it appears as a radar icon on your map.

How ARC Probes function and why they matter

ARC Probes are static beacons that land from orbit, broadcasting a siren once breached. They never directly damage players but trigger:

  • Local attraction of ground ARC patrols.
  • Repeated air reinforcements (typically one Hornet plus two Wasps) if the breach timer runs long.

Fast, coordinated breaches minimize these responses, making probes a high-reward, low-risk objective when handled correctly.

How to breach an ARC Probe safely

Step 1

Scout and clear nearby static defenses such as turrets or cameras to prevent surprise alarms.

Step 2

Position two lines of cover with sightlines to the sky; use these spots to dodge incoming drone fire.

Step 3

Engage the first panel breach quickly—once you start, finish before reinforcements arrive.

Step 4

Watch for the first wave of Wasps. Their laser telegraphs: step out of the endpoint before it turns red, then punish them.

Step 5

Respect the Hornet’s stun round: break line of sight as it telegraphs, then focus rear rotors.

Step 6

Move immediately to the second panel and begin the breach, swapping cover as needed.

Step 7

If reinforcements stack up, kite them away from the probe, thin the group, then return to finish the final panel.

Step 8

Collect loot and exfiltrate before the next probe wave spawns elsewhere—avoid lingering around after all panels are open.

Expected ARC Probe loot

Panel roll Possible quantity
ARC Alloys 0–2
ARC Powercell 0–1
ARC Circuitry 0–1
ARC Motion Core 0–1
ARC Flex Rubber 0–1
Recipe 0–1

Each of the three panels can yield separate rolls. Dismantling nearby drones mid-breach often drops extra PowerCells to sustain shields.

Consistently hunting ARC Probes sharpens situational awareness and rewards you with crafting materials and rare schematics. By learning spawn hotspots and practicing rapid breach routines, you’ll integrate Prospecting Probes into every extraction route, boosting efficiency and loot haul.
