The Hidden Bunker is one of the newest events added to Arc Raiders that lets players farm up a ton of XP and loot within a short span of time, provided they can complete the puzzle that comes with it.
However, if you’re new to Arc Raiders or just haven’t played enough of the latest event, you might find yourself getting confused when trying to find the location of the mysterious Hidden Bunker.
In this guide, we’ll walk you through everything you need to know about the Hidden Bunker location in Arc Raiders while also taking a look at the puzzle you need to solve during the event.
Arc Raiders Hidden Bunker Event Times
At the time of writing, the Hidden Bunker in Arc Raiders can only be accessed in the Spaceport map. You can only access this event during the following times:
- 10:00 AM – 11:00 AM UTC
- 7:00 PM – 8:00 PM UTC
Upon queuing for the event, you’ll enter a 40-minute raid in Spaceport (unless you join mid-game), with the extended timer giving raiders plenty of time to complete the puzzle and explore the Hidden Bunker.
Arc Raiders Hidden Bunker Location & Puzzle Explained
Once you’re in the raid, you’ll have to find four antennas located at four different corners of the map and activate them to open up the Hidden Bunker in Spaceport.
The location of the antennas will be highlighted on your map, but note that other raiders will also be working to activate the antennas, so it’s unlikely you’ll have to do all the work yourself.
Upon activating all four antennas, everyone in the raid will receive a message on their screen notifying them that the Hidden Bunker has now opened for all players.
When you see this message, head to the southwest of the Departure Building to find the Hidden Bunker entrance. We have highlighted the location of the Hidden Bunker entrances in the image below for your convenience.
Once you’re inside the Hidden Bunker, you’ll be able to find a ton of good loot, including weapons, ammo, grenades, crafting materials, and more. You’ll also be able to farm up a ton of XP by opening containers and downloading data from eight terminals scattered throughout the bunker. Be wary, though, as the bunker is infested with Ticks, Fireballs, and Pops, which can easily take down your entire HP pool if they catch you off-guard.
The community has yet to decide whether the terminals in the Hidden Bunker are linked to a different puzzle or are just there for XP and trials.
