ARC Raiders has just been updated with a new Map Condition, and this one requires players to head to Spaceport to find the Hidden Bunker, but it’s quite a tricky challenge. If you want to find and open the Hidden Bunker, you’ll first need to accomplish four tasks that almost definitely require back-up to get done quickly enough in-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 location is found between Fuel Lines and Fuel Processing on Spaceport, and it’s admittedly a pretty obvious door for something that’s classified as being ‘hidden’.

Unfortunately, you can’t just run up and open the Hidden Bunker, as there are four objectives to accomplish first, all of which are identical.
There are four antennas spread around the map, and they’re instantly visible when you open your Spaceport map, indicated by the white ‘pylon’ symbol. They’re easy enough to get to, but once you activate each one, two things will happen:
- Everyone in the lobby will know you’ve activated that antenna
- ARC will descend upon you in a flurry of attacks
Once all the antennas have been activated, every player in the lobby will be told that the Hidden Bunker is now open, but it doesn’t appear on anyone’s map – you need to find it.
Fortunately, by using the image above and looking for a very obvious and heavy door set into the sandy ground, you’ll find the Hidden Bunker in ARC Raiders before anyone else can.
Once you’re inside, you’ll want to prioritize downloading the data on the eight terminals found within, which award you 500 XP per terminal. There might be other secrets hiding within, but if there are, nobody has found them yet.
BE WARNED: Every player in the lobby has the potential to access this bunker, so if they’re not there when you turn up, they might be waiting for you outside when you leave.
