How to open the hidden bunker on Spaceport

When you start a match on the Hidden Bunker map at Spaceport, four antenna icons will appear randomly on your map. Use the icon shown to help you find them.

The bunker will open when raiders activate certain antennae during a match. It doesn’t require a single team to activate all of them – different teams can work on different antennae to open the bunker faster.

Many of the antennae are hard to get to—you might even need a zipline to reach them. If you’re trying to open the secret bunker, it’s a good idea to bring extra antennae with you.

When you start activating an antenna, enemies will appear nearby. You need to defeat these enemies first. Once they’re gone, go back to the antenna and select the option that says “Send unlock signal” to finish activating it.

Once all four antennas are turned on, a message will be sent to everyone in the game letting them know the secret bunker is now accessible.

Where to find the hidden bunker entrance on Spaceport

Okay, so I finally figured out how to get into the bunker! It’s not enough to just know how, you also need to find it. It’s over on the west side of Spaceport, in that rocky area right next to the Fuel Processing building. It’s easy to miss, but that’s where it is!

Getting inside the bunker is only the first step. A larger, more complex mystery awaits within its walls.

The hidden bunker is filled with weapon and ammo crates that raiders have left behind. A careful search of the rooms could turn up some useful guns or weapon blueprints. But there’s also a mysterious extra objective waiting for anyone who ventures inside.

Throughout the bunker, you’ll find several computer terminals. Interacting with them lets you and your fellow raiders download data, earning 500 XP per download. The download takes a little time, but it’s currently unclear what players are supposed to do after getting the data.

We’re all working to understand what else we can do in the hidden bunker now that we’ve downloaded the data. We’ll update this guide with any new discoveries we make.
