How to Solve the Hidden Bunker in Arc Raiders – New Puzzle Event on Spaceport
A new “Map Condition” has just been added to ARC Raiders, and this one is a high-stakes, lobby-wide race for glory. The event sends players scrambling across the Spaceport map to find and unlock a secret Hidden Bunker. But it’s a tricky challenge that requires you to complete some dangerous tasks before you can plunder the treasures within.
This isn’t a simple loot run; it’s a puzzle that almost certainly requires cooperation. In this guide, we’ll show you exactly how to find and open the Hidden Bunker on Spaceport and what to do once you’re inside.
Recommended Preparation

This is a high-risk, high-traffic event. The entire lobby will be competing for the same prize, so you must go in prepared. Don’t try to play this as a hostile solo, unless you know exactly what to do – try to cooperate to increase your chances of solving the puzzle and extracting with the loot:
- Bring Utility: The Antennas you need to activate can spawn behind Locked Doors, so bring Ziplines to access them.
- Gear for a Fight: You will be attacked by swarms of ARC drones and, more importantly, other players. Bring your best armor, your most reliable weapons, and plenty of meds.
- Study the Map: Use our Spaceport Interactive Map. Before you even load in, identify the locations of the four antennas and memorize the location of the Hidden Bunker itself.
Step 1: Activate the Four Antennas
The first step to opening the bunker is to activate four antennas spread across the map. These are easy to find, as they are clearly marked on your in-game map with a white ‘satellite’ symbol. You can’t miss them – below is an Example, but the Antennas can spawn in other places during your raid!

Be ready for a fight. The moment you activate an antenna, two things happen immediately:
- The entire lobby gets a notification that you’ve activated that specific antenna.
- A flurry of ARC units will immediately descend on your position to attack.

This is why it’s useful to team up with other Solos or go in as a Squad – other Raiders can cover you and help you deal with the ARC drones that spawn once the Antenna is activated.
Step 2: Find the Hidden Bunker in Arc Raiders Spaceport Map
Once all four antennas are active, the entire lobby will get a notification: “The Hidden Bunker is now open.” Here’s the catch: the bunker’s location does not appear on anyone’s map. This is where your preparation pays off.

The Hidden Bunker is located between the Fuel Lines and Fuel Processing POIs. For something “hidden,” it’s a pretty obvious, heavy-duty hatch-door set into the sandy ground. Head there once you know that all Antennas have been activated! There are a couple of entrances to the Hidden Bunker, but they are all in a close proximity to each other.
Step 3: Download and Retrieve Data inside the Hidden Bunker
Getting inside is only the first part of the challenge. Once you’re in the bunker, you’ll be able to find eight data terminals (PCs), each with a light above it. Your main objective is to download the data from all of them.

You must interact with each active terminal and stay close to it to complete the download. According to our intel, one player must retrieve all the data files from every Terminal. You could try to coordinate with your squad to have one designated “data runner” while the others defend the room and watch the entrances.
Once you retrieved all the Data from each Terminal, the next step is currently unknown and we are trying to progress and figure out this puzzle together with ARC Raiders Community on Discord. What an exciting activity from Embark Studios bringing the whole lobby together! AS SOON AS WE KNOW MORE DETAILS, this article will be updated with full solutions and the rewards information!
