• Retrieve data from the bunker
Hidden Bunker is a map modifier that grants access to a bunker complex on Spaceport, located west of the Departure Building.

To unlock the bunker, Raiders must activate four rooftop antenna dishes. These antennas spawn randomly on different rooftops near the center of the map. Any antennas that haven’t been activated yet will show up as icons on the map fully zooming out often makes them much easier to spot.
All antennas can be activated by a single player, or split between multiple Raiders. Progress is shared across the entire lobby.
Each antenna requires two interactions:
- First interaction: triggers a short alarm and spawns Wasp and Hornet ARC. Defeat them to continue.
- Second interaction: completes the antenna and displays a progress message to everyone in the lobby.
Once all four antennas are completed, the Hidden Bunker is revealed. It has multiple entrances, all located immediately west of the Departure Building.
Inside the bunker, you can interact with any terminal to start a download sequence, which can be monitored on the terminal’s screen. After the download finishes, you have a limited window to interact with the terminal again and retrieve the data. This can be done four times total, each time requiring a different terminal.
Additional info
- Maximum raid duration: 40 minutes
- The bunker is guarded by 2× Bastion and 1× Bombardier
- The bunker has 2 entrances
