ARC Raiders Hidden Bunker Guide – Antennas, Loot & Strategies

What Is the Hidden Bunker?

The Hidden Bunker is a secret event location in ARC Raiders, mainly appearing on the Spaceport map. Only active under certain conditions, it extends match duration and limits standard extraction points, making it a high-stakes objective for players seeking loot, XP, and event completion. 

How to Unlock the Hidden Bunker

• Activate 4 antennas scattered across the Spaceport map. 

• Each antenna requires two interactions:

  1. Triggering a wave of ARC enemies (Hornets, Wasps, etc.)

  2. Sending the unlock signal once the wave is defeated 

• Progress is shared across all players, so teamwork or competition influences who reaches the bunker first.

Tip: Mobility tools like ziplines or grappling hooks are highly recommended to reach antennas on rooftops. 

Bunker & Antenna Locations

Map & Antenna Overview

• Hidden Bunker events only happen on the Spaceport map 

• 4 antenna icons appear on the mini-map (satellite dish symbols), representing rooftop locations

• Positions are randomized per raid, usually following a “north, east, south, west” distribution
  

Common Antenna Locations

• North Antenna – South Trench Tower rooftop 

• East Antenna – Near Rocket Assembly 

• West Antenna – Top of the Departure Building

• South Antenna – Around Vehicle Maintenance, NW corner 

• Other possible spawn rooftops: shipping warehouse, control tower, container storage 

Tip: Some antennas require vertical traversal; ziplines or grappling hooks are essential. 

Bunker Entrance

• After all antennas are activated, the entrance appears in the southwest of Spaceport, between Fuel Processing and Fuel Lines, south of the Departure Building 

• Multiple entrances exist: one near rubble/rocky terrain, another by the Departure Building

• Until unlocked, the bunker isn’t visibly marked on the map. Mini-map icons only appear for antennas. 

• Entrances are guarded by ARC enemies, including Bastions and Bombardiers
  

Navigation Tips

• Scout antenna icons as soon as you enter the map

• Split antenna tasks among teammates for efficiency

• Prepare for enemy waves when activating antennas 

• Be ready for PvP competition once the bunker is announced open

• Know all entrances to plan extraction or defensive positioning

Inside the Bunker

• 8 data terminals allow players to download data for XP rewards

• Terminals are guarded by ARC enemies like Bastions and Bombardiers

• Players must stay near terminals during downloads to avoid failure
