Finding the Hidden Bunker Location
The Hidden Bunker is located southwest of the Departure Building, positioned between Fuel Lines and Fuel Processing. Look for heavy metal doors set into the sandy terrain—there are multiple entrance points around this mound area.
Before you can enter, four rooftop antenna dishes must be activated, which spawn randomly across different rooftops near the map center. These are clearly marked on your in-game map with white satellite dish icons.
How to Activate the Four Antennas
Step 1: Locate the Antennas Open your map immediately upon spawning. The four antennas appear as white satellite symbols on random rooftops across Spaceport.
Step 2: Prepare Your Loadout Bring ziplines to access antennas behind locked doors or on hard-to-reach rooftops. Some antenna locations like the North and South Trench Towers require ziplines or special keys.
Step 3: Establish Connection Climb to the rooftop and interact with the console at the antenna’s base. Once you activate an antenna, the entire lobby gets a notification and ARC units immediately descend on your position.
Step 4: Defend and Activate Fight off the spawned Wasps and Hornets, then interact with the console again to send the unlock signal. Repeat this process for all four antennas—different teams can activate different antennas cooperatively.
Inside the Hidden Bunker
Eight terminals are scattered throughout the bunker, each awarding 500 XP when you download data. Stand near terminals while the green progress bar fills, then retrieve the data. Be cautious—smaller ARC units like Ticks lurk in the darkness, and rival squads are racing for the same loot.
The bunker contains breachable containers, raider caches, and high-tier equipment. Extraction is critical—dying before leaving means losing everything.
Pro Tips for Success
Team Coordination: Solo attempts are extremely difficult. Teaming up with other solos or going in as a squad helps deal with ARC drones and provides defensive coverage.
Clear Before Looting: Eliminate all nearby threats before interacting with terminals or containers. You’re vulnerable while downloading data.
Plan Your Exit: The nearest elevator is approximately 100 meters north of the bunker entrance. If overwhelmed, sprint halfway and crawl the rest.
Bring Essential Gear: Pack weapons and gadgets suitable for both rooftop combat and close-quarters bunker fighting.

Frequently Asked Questions
Q: Can I complete the Hidden Bunker solo?
While technically possible, solo completion is extremely challenging due to simultaneous threats from ARC reinforcements and hostile players. Squad play dramatically improves success rates, especially when activating antennas that trigger server-wide alerts.
Q: Do the antennas spawn in the same locations every time?
No, antenna locations randomize with each Hidden Bunker event session. Always check your map immediately upon loading into Spaceport to identify the current antenna positions and plan your route accordingly.
