If you've loaded up Arc Raiders and noticed that Spaceport is currently home to the Hidden Bunker map condition, you may be interested in figuring out how you can reach the bunker and see what's inside. In this guide, we'll walk you through what you (and potentially the rest of the raid) need to do to pop open that bunker and take a look at what's hiding within.
When you load into Spaceport during the Hidden Bunker map condition, you can open your map to find a total of four antenna icons scattered across the map at random locations. Look for the icon below to identify their locations.
Antenna icon
To open the bunker, these antennae will need to be activated by raiders during the match. That being said, it doesn't have to be the same team activating them all--meaning different teams can activate different antennae to get the bunker open more quickly.
Note that some of the antennae are difficult, if not impossible, to reach without a zipline, so it's not a bad idea to bring a few in if you're working toward unlocking the hidden bunker.
When activating an antenna, ARC will spawn nearby that must be defeated before you can wrap up the antenna's activation. When you've defeated them, return to the antenna and interact with the prompt that says "Send unlock signal" to complete the activation.
When all four antennae have been activated, a raid-wide announcement will go out to inform everyone in the match that the hidden bunker has been opened.
Unlocking the bunker doesn't mean much if you aren't sure where to find it, right? The hidden bunker can be found on the western side of Spaceport in the rocky field just east of the Fuel Processing POI.

Opening and entering the bunker is just the beginning, though. There's a much bigger mystery at play within.
Inside the hidden bunker are a wide variety of weapon and ammo crates for raiders to loot. You may be able to score a few good guns or blueprints by thoroughly searching the rooms here. However, there's quite an intriguing additional task waiting for you inside, too.
Scattered around the bunker are multiple terminals you and other raiders can interact with to download data for 500 XP each. You'll need to stand near the terminal for a bit for the data to download and grant you this experience, then you can pick up some data by clicking "Retrieve Data" on the console--but what exactly players are expected to do afterward remains a mystery.
Stay near the console while you wait for the green bar to fill up.
The community (including us) is working hard to figure out what else may be able to be accomplished down in the hidden bunker after downloading the data from the terminals. Rest assured that we'll be sure to update this guide if and when we discover new information.
