ARC Raiders: Spaceport Hidden Bunker Location Guide

ARC Raiders’ newest map condition has added a thrilling new mystery — the Hidden Bunker on the Spaceport map. It’s not just a regular locked door; opening it requires coordination, timing, and combat readiness. Here’s a complete breakdown of where to find it, how to open it, and what dangers to expect inside.

Where to Find the Hidden Bunker on Spaceport

The Hidden Bunker is located in the southwestern region of the Spaceport map, sitting between Fuel Lines and Fuel Processing. At first glance, it looks like a sealed, heavy metal door set into sandy terrain — easy to overlook if you’re not paying attention.

This bunker used to be just scenery, but during the current map condition rotation, it’s finally active. When the Hidden Bunker condition is live, special interactive objectives appear around the map, allowing players to unlock it.

How to Open the Hidden Bunker

Unlocking the Spaceport bunker isn’t as simple as finding a key — it’s an event-driven process that involves multiple objectives and waves of enemies.
Here’s the full process:

Locate Four Antennas (or Buttons)
- Four antennas appear across the Spaceport map, marked with a white pylon symbol.
- These can also appear as button prompts depending on your instance; treat them the same way.
Activate Each Antenna
- Interacting with an antenna triggers ARC swarms, including Wasps and Hornets.
- Defeat the wave, then finish the activation sequence.
Trigger the Global Announcement
- Once all four antennas are activated (by you or other squads), every player in the raid receives a message: “The Hidden Bunker has been unlocked.”
- Note: The exact location doesn’t appear on the map — you’ll have to find it manually.
Race to the Bunker Entrance
- Head toward the southwestern area between Fuel Lines and Fuel Processing.
- Look for a large, reinforced door embedded in the ground — that’s your entrance.
Enter and Secure the Interior
- Inside, you’ll find data terminals.
- Each terminal grants 500 XP when downloaded. Start all downloads simultaneously to complete the puzzle efficiently.
- Watch out: Other players may follow you in or camp outside waiting for you to exit.

Alternative Access: Spaceport Outskirts Bunker Key

If the map condition isn’t active, you can still enter the bunker with the Spaceport Outskirts Bunker Key.

This consumable key can be looted in residential areas or as a random drop from other maps like Dam Battlegrounds.
It grants direct entry to the same bunker located far west on the Spaceport map, skipping the antenna event.

Be cautious — the door animation alerts nearby players, and this area is a PvP hotspot.

What’s Inside the Hidden Bunker

Once inside, you’ll find:

Eight data terminals, rewarding XP and potential loot.
High-tier components rumored to drop during this event.
Challenging encounters, as ARC enemies and rival Raiders often converge on the site.

Players suspect there may be more undiscovered secrets within, but as of now, the data terminals are the confirmed reward source.

Tips for Players

Coordinate with a squad: Solo raiders can activate antennas, but clearing waves is risky.
Travel light: You’ll need stamina for running between antennas and dodging ambushes.
Use cover wisely: The western ridge offers limited protection from long-range attacks.
Plan your extraction: Once you’ve looted the bunker, have a clear escape route before the latecomers arrive.

The Spaceport Hidden Bunker is one of the most exciting additions to ARC Raiders’ evolving world. Whether you’re chasing XP or rare loot, the challenge of unlocking and surviving the bunker makes it a must-visit event for every raider. Just remember — once the antennas go live, everyone knows, and the real fight begins. Play Now!
