The Hidden Bunker in ARC Raiders: Unlocking and Exploring the Secret
The Hidden Bunker is a new version of the Spaceport map in ARC Raiders. This special event offers players an extended match time of 40 minutes to unlock the Hidden Bunker, discover its location, and unravel the mysteries it contains.
Where to Find the Hidden Bunker
The Hidden Bunker is located southwest of the Departure Building on the southwest side of the Spaceport map. You’ll find several entrances around a mound leading down into the bunker. Be aware that a Bastion—and sometimes a Bombardier—circles the area.
At the start of the match, the Hidden Bunker is locked, meaning you will have to complete certain tasks before gaining access.
How to Unlock the Hidden Bunker
To unlock the Hidden Bunker, you must activate four antennas positioned at each major cardinal direction on the Spaceport map:
- North: South Trench Tower (requires a zipline)
- East: Rocket Assembly
- South: Vehicle Maintenance
- West: Departure Building
Each antenna is located on the roof of a building. If you spawn near one, it’s your responsibility to activate it. The northern antenna on the South Trench Tower can only be accessed using a zipline, so make sure to come prepared.
To activate an antenna, climb to the roof and locate the computer terminal beneath the satellite dish. Interact with the terminal to establish a connection. Be ready—once the connection is triggered, ARC reinforcements will attack your position. After the connection is made, interact again with the console to send the unlock signal.
Once an antenna is successfully activated, all players on the map will see an on-screen message indicating which antenna has been completed (e.g., “[North/East/South/West] antenna has been successfully activated”). Additionally, the satellite icon for that antenna will be removed from the map.
After all four antennas have been activated, head to the Hidden Bunker southwest of the Departure Building to proceed with the next step.
How to Solve the Hidden Bunker
Currently, there is no clear consensus on whether a puzzle exists inside the Hidden Bunker. The primary rewards appear to be breachable containers and the ability to download data.
Here’s what you need to do to interact with the bunker terminals:
- Find a terminal with the “Start download” prompt.
- Stay close to the computer while the data downloads.
- When the green progress bar fills, interact again with the terminal to “Retrieve data.”
After retrieving the data, the terminal’s green light will turn red after 25 seconds, entering a cooldown period lasting a few minutes. It seems you can only download data once from each console per match, but other players can download from it as well.
Why Download Data?
At the time of writing, there is a Weekly Trial that requires players to download data during the Hidden Bunker event. The more data you download, the higher your score—helping you progress through the ranks.

Is There More to the Hidden Bunker?
Whether there is a secret beyond the data downloads remains unknown. There have been matches where all terminals’ data were retrieved simultaneously, but nothing additional occurred. There could be more hidden within the bunker, so dive in and explore—you might discover something new!
