How to Open the Hidden Bunker in ARC Raiders—New Map Condition Guide

by

A new update to ARC Raiders introduces a challenging Map Condition that sends players to Spaceport in search of a Hidden Bunker. Finding and opening this bunker requires completing four tasks, and it’s likely you’ll need help from teammates to do it quickly during a raid.

In this guide, I’ll teach you how to open the Hidden Bunker on Spaceport as quickly as possible.

Where is the Hidden Bunker on Spaceport?

The Hidden Bunker is located on Spaceport, between the Fuel Lines and Fuel Processing areas. It’s surprisingly easy to find, despite being labeled as ‘hidden’.

You can’t simply access the Hidden Bunker right away. First, you need to complete four identical objectives.

You’ll find four antennas scattered across the map, clearly marked with a white ‘pylon’ symbol as soon as you open your Spaceport map. They’re fairly accessible, but activating each one triggers two effects:

  1. Everyone in the lobby will know you’ve activated that antenna
  2. ARC will descend upon you in a flurry of attacks

Once the antennas are all turned on, everyone in the game will receive a message saying the Hidden Bunker is open. However, it won’t automatically show up on your map – you’ll have to search for it.

Luckily, you can find the Hidden Bunker in ARC Raiders quickly by using the image as a guide and searching for a large, noticeable door built into the ground.

Once you’re inside, your first goal should be to download data from the eight terminals – each one gives you 500 XP. While there might be other hidden things to discover, no one has found them so far.

Just a heads-up from someone who’s played a lot: be careful with this bunker! Anyone in the game can get in, so if you don’t see other players inside, they might be camping right outside waiting for you to come out. It’s a real risk!
