How To Unlock And Locate The Hidden Bunker

ARC Raiders is off to an outstanding start with a concurrent player count that continues to climb and is now north of 400,000. New alternating game modes have also been added into the mix, including Blue Gate night raids, electromagnetic storms, and a hidden bunker mode that may or may not have an unsolved mystery.

The new hidden bunker mode requires players to interact with four antennas placed at different parts of the Spaceport map, which will unlock the entrance to a hidden bunker—but that’s easier said than done. Luckily for you, my Raider, Gorgon, recently teamed up with six other solo Raiders in an epic mission to scout out the antennas, send the unlock signals, and locate the bunker entrance.

Buckle up, Raider, Gorgon will show you the way.

Head To The Surface

To get this mission started, select the hidden bunker mode on the Spaceport map (seen above), and make sure you bring a zipline with you as you’ll need it to reach one of the antennas.

Hidden Bunker Antenna Locations

Once you’ve reached the surface, take a look at your map, and you’ll notice four antennas placed at various locations around the map. These locations alternate so they won’t always be in the same spot, but you’ll commonly see them on top of the Departure Building, Rocket Assembly, Control Tower, the North and South Trench Towers, Vehicle Maintenance, and the Shipping Warehouse.

Most of these rooftops are easily accessible via ladders or staircases, so seek out the antenna closest to you when you spawn in, ascend to the rooftop, and interact with the terminals seen below.

Establish Connection And Send The Unlock Signals

First, you’ll need to establish the connection, and you’ll need to stay close by and wait until it’s finished. Once the antenna is connected, you’ll need to interact with it again to send the unlock signal.

When the unlock signal is sent, a swarm of ARCs will descend upon you, so be ready to defend yourself!

If an antenna has already been used to send an unlock signal, it will no longer appear on the map.

Use Your Zipline

The North and South Trench Towers (seen above) are the only locations that pose a real obstacle, as you’ll need to either use a zipline, or a Trench Tower Key to get to the rooftops.

Once all four unlock signals have been sent, you’ll receive the notification (seen below) that the hidden bunker is now open, but the entrance to it isn’t revealed on the map.

Fortunately, Gorgon and his squad of friendly followers have located the entrance and marked it on the map seen below.

Hidden Bunker Location

This entrance is located between the Fuel Lines and the Fuel Processing Area, and can be seen in the picture above.

Be careful Raider! Bastions and Bombardiers patrol this area diligently.

Go inside the hidden bunker entrance (seen above).

Download And Retrieve The Data

Once you’re inside the hidden bunker, search around until you find the terminals seen above.

When you interact with them, you’ll need to start a download and stay right beside it until the download finishes. When the download is successful, the light will turn green, and you’ll be able to interact with it again to retrieve data—this will reward you with 500 XP for exploration.

If you move away from the terminal while it is downloading, it will fail, the light will turn red, and you won’t be able to retrieve the data.

There are many of these terminals scattered throughout the hidden bunker, and while they provide a great way to farm XP and level up quickly, theories have been circulating within the gaming community that suggest these terminals are actually a puzzle that has yet to be solved.
