Here’s the clearest summary of what the community has pieced together so far:
- Activate all 4 Antennas on different edges of the Spaceport map (bring Ziplines)
- Head to the Hidden Bunker on the south-west side of Spaceport (details below)
- Inside, interact with all 12 Data Terminals to Download Data
- After downloads complete, Retrieve Data from each terminal
- The next step is still being solved by the ARC Raiders community — share findings on your Discord
Recommended Preparation
This isn’t a casual loot run. Expect heavy PvP and constant pressure.
- Bring utility (Ziplines): Antennas can spawn behind Locked Doors, so mobility tools matter.
- Gear for a fight: You’ll get swarmed by ARC drones, and other Raiders will absolutely show up. Bring strong armor, reliable weapons, and lots of meds.
- Study the map first: Use your Spaceport Interactive Map to identify likely antenna locations and memorize where the bunker hatch is before you load in.
Also: don’t try to brute-force this as a hostile solo unless you already know the flow. Cooperation (even temporary) boosts your odds massively.
How to Do the Hidden Bunker Map Condition
A new Spaceport “
” has landed, and it plays like a lobby-wide race. Players scramble across the map to unlock a secret bunker, but you’ll have to complete multiple dangerous steps before you get access to the rewards inside.
This is almost certainly designed with teamwork in mind — not because it’s impossible solo, but because the event broadcasts your progress and attracts attention fast.
Step 1: Activate the Four Antennas
To unlock the bunker, you must activate four antennas spread around Spaceport.
- Antennas are easy to identify: they’re marked on your in-game map with a white satellite icon.
- Important: antenna positions can vary — you may not see the same exact spots every raid.
The moment you activate an antenna…
Two things happen immediately:
- The entire lobby receives a notification that you activated that antenna.
- ARC units rush your position, usually in a quick swarm.
This is why it’s smart to squad up or temporarily cooperate with other solos — someone can cover the activation while the others clear drones and watch angles.
Step 2: Find the Hidden Bunker Location (Spaceport)
Once all four antennas have been activated, everyone gets the message:
“The Hidden Bunker is now open.”
Here’s the catch: the bunker does NOT appear on your map. If you didn’t prepare, you’ll lose time searching while other players beeline straight to it.
Where it is
The Hidden Bunker is located between the Fuel Lines and Fuel Processing POIs on Spaceport.
For something “hidden,” it’s not subtle: you’re looking for a heavy-duty hatch door set into the sandy ground. There are a couple of entrances, but they’re all close to each other.
Once you know all antennas are active, get moving — the longer you wait, the more likely the bunker becomes a PvP choke point.
Step 3: Download Data Inside the Bunker (12 Terminals)
Opening the bunker is only the beginning. Inside, you’ll find twelve data terminals (PCs), each with a light above it.
Your objective: download data from all twelve terminals.
- Interact with each active terminal
- Stay close to it while the download completes
- Expect interruptions: people will push in, and fights tend to break out mid-download
Coordination tip (best known approach)
Based on current intel, one player may need to retrieve all data files from every terminal. A strong setup is:
- 1 designated data runner
- 1–2 defenders watching entrances and controlling the room
This keeps progress consistent while the rest of the squad focuses on survival and area control.
