If you have finished loading Arclight Guide And noting that the spaceport is currently home to a hidden bunker map condition, you might be interested in figuring out how to get to the bunker and see what's inside. In this guide, we'll walk you through what you (and possibly other members of your team) need to do in order to open the bunker and see what's hidden inside.
How to open the hidden bunker in the spaceport
When you load into the spaceport in the Hidden Bunker map condition, you can open the map to find a total of four antenna icons scattered in random locations on the map. Look for the icons below to identify their locations.

To open the bunker, these antennas need to be activated by the attacker during the game. That being said, it's not necessarily the same team activating them – which means Different teams can activate different antennas to open cover faster.
Notice Some antennas are difficult, if not impossible, to reach without zip linesso if you're working on unlocking hidden bunkers, it's not a bad idea to bring some in.
When activating an antenna, an ARC will spawn nearby and must be defeated before the antenna's activation can end. after you defeat them Return to the antenna and interact with the prompt “Send unlock signal” to complete activation.
When all four antennas are activated, a team-wide announcement will go out, informing everyone in the match that the hidden bunker has been opened.
Where is the hidden bunker entrance to the spaceport?
There's not much point in unlocking the bunker if you're not sure where to find it, right? The hidden bunker is located in the rock field east of the Fuel Processing POI on the west side of the spaceport.

Opening and entering the bunker is just the beginning, though. There is a bigger mystery hidden here.
Arc Raiders Hidden Bunker Loot
Hidden bunkers contain a variety of weapons and ammo boxes for attackers to loot. By searching the rooms here thoroughly, you might be able to get some good guns or blueprints. However, there's a rather interesting extra mission waiting for you inside.
There are multiple terminals scattered around the bunker that you and other raiders can interact with and download data for a cost of 500 XP each. You'll need to stand near the terminal for a while for the data to download and grant you this experience, and you can then grab some data by clicking “Retrieve Data” on the console – but exactly what the player will do after that remains a mystery.

The community (including us) is working hard to figure out what else can be accomplished in the hidden bunker after downloading the data from the terminal. Rest assured, we'll be sure to update this guide if we discover new information.
