Hidden Bunker in ARC Raiders – Locations, Spaceport & More
The ARC Raiders Hidden Bunker is a Spaceport map condition that turns the raid into a lobby wide race. You unlock it by activating four rooftop antennas, then you go inside and use the data terminals.
Most players miss it because the bunker is locked at the start, the antenna rooftops change, and the bunker itself is not marked on the map.
This page gives you a clean checklist. Confirm the condition, locate the bunker, activate the antennas, retrieve data, then extract.
It stays focused on the Hidden Bunker steps only. It does not cover full Spaceport loot routes or Trials ranking theory.
ARC Raiders Hidden Bunker Assumptions
Find The Entrances
The bunker is on the southwest side of Spaceport. It is not marked on the map, so you need to recognize the area.
Unlock Requirement
Four satellite dish icons appear on your map when the condition is active. Each antenna needs two interactions.
Data Progress
Inside the bunker, use terminals with the “Start download” prompt, stay close, then “Retrieve data.”
ARC Raiders Hidden Bunker Forks
Use these forks so you do not waste a full raid doing steps that cannot work in your current run.
- If you are not on Spaceport: this guide does not apply. Extract, queue Spaceport, then go to ARC Raiders Hidden Bunker Spawn Check.
- If you do not see satellite dish icons on your map: Hidden Bunker is not active in this raid. Stop and play normally, or requeue. Then go to ARC Raiders Hidden Bunker Spawn Check next run.
- If you already saw “The Hidden Bunker is now open”: skip antennas and go to ARC Raiders Hidden Bunker Entry.
- If you keep dying on rooftops: go to ARC Raiders Hidden Bunker Antennas and use the safe path notes before you attempt a full four antenna run.
ARC Raiders Hidden Bunker Spawn Check
Type: Diagnostic check. This tells you if the Hidden Bunker steps can work in your current raid.
- Queue into a Spaceport raid.
- Open your map as soon as you load in.
- Look for the satellite dish icons. These icons mark the antenna rooftops for this run.
- If you do not see those icons, treat this as a normal Spaceport raid.
ARC Raiders Hidden Bunker Location
Type: Navigation fix. This gets you to the bunker entrances so you can rotate back the moment the last antenna is finished.
The Hidden Bunker sits on the southwest side of Spaceport. It is near the outskirts, and it is not marked on your map as a special icon.
- Open your map and locate the southwest side of Spaceport.
- Move toward the area between Fuel Lines and Fuel Processing.
- Look for a sandy mound with multiple heavy bunker style entrances clustered close together.
- Note the safest approach route so you can return fast after antennas are complete.
ARC Raiders Hidden Bunker Antennas
Type: Root cause fix. The bunker stays locked until all four antennas are completed.
Each antenna is on a rooftop and is marked by a satellite dish icon on your map. Antenna locations can change between raids, so always follow your current map icons.
Each antenna is completed with two interactions. The first interaction establishes the connection and can trigger ARC reinforcements. The second interaction sends the unlock signal and marks the antenna complete.
- Open your map and choose the closest satellite dish icon.
- Reach the rooftop and find the console below the satellite dish.
- Interact with the console once to establish the connection.
- Clear the incoming ARC reinforcements around the roof.
- Interact with the console again to send the unlock signal.
- Repeat this process until all four antenna icons have been cleared from the map.

Type: Execution step. This is the fast rotation back to the bunker once it is open.
Once all antennas are done, the bunker entrances can be used. Expect danger near the mound. Bastion patrols can be present, and a Bombardier can sometimes circle the area.
- Rotate back to the Hidden Bunker mound on the southwest side of Spaceport.
- Check the clustered entrances and pick the safest entry line.
- Clear immediate threats near the entrance before committing to the descent.
- Enter the bunker and move off the entrance choke point.
ARC Raiders Hidden Bunker Terminals
Type: Objective completion. This is how you convert a successful unlock into real progress, like “Download Data” style objectives.
Inside the bunker you can find multiple data terminals. Each usable terminal shows a Start download prompt. After the download completes, you get a Retrieve data prompt for a limited time.
- Find a terminal with the Start download prompt.
- Interact once to start the download.
- Stay close to the terminal until the download finishes.
- Interact again to Retrieve data.
- Move to the next terminal and repeat as needed.
- If a download cancels, return to that terminal and retry if it is still available.
ARC Raiders Hidden Bunker Extraction
Type: Survival step. If you do not extract, you do not lock in the run.
Extraction options can change across raids, so always confirm what is available in your current session. Use your map and plan around the closest active Return Point.
- Open your map and identify your closest active Return Point.
- Start rotating before you are fully committed to a last second sprint.
- Extract and hold position until the extraction completes.
- If your chosen Return Point closes, reroute to the next active one immediately.
