After being temporarily removed in Patch 1.5.0 and officially returning in Patch 1.7.2, many players are once again questioning whether this Spaceport-exclusive event is still worth the time and risk.
Before deciding whether to farm it regularly—especially if you are managing your resources or considering ARC raiders coins cheap options—it’s important to fully understand how Hidden Bunker works and what it actually offers.
What Makes Hidden Bunker Different from Other Map Events?
Unlike global map modifiers such as Night Raid or Electromagnetic Storm, Hidden Bunker does not affect the entire Spaceport map. Instead, it introduces a sealed bunker complex located on the western side of the Departure Building.
During this event:
Raider Hatches are disabled
Available extraction points are reduced
Enemy density and patrol strength increase
This design significantly raises the risk level, especially for solo players.
How to Activate the Hidden Bunker Event
Once you enter a Spaceport match where Hidden Bunker is active, four antenna markers will appear on your minimap, positioned roughly in the north, east, south, and west.
Their exact locations change each match, but they always spawn on rooftops. Using elevated terrain or long sightlines helps speed up discovery.
Each antenna must be activated manually:
Interact with the terminal at the base
Defeat the spawned Wasp and Hornet units
Interact again to complete activation
Progress is shared across the entire lobby. Once all four antennas are activated, a system message confirms that Hidden Bunker is open.
Bunker Entrance and Enemy Threats
The main entrance lies between Fuel Processing and Fuel Lines on the southwest side of the map. Two Bastions and one Bombardier patrol the area constantly, making stealth or coordinated combat essential.
Inside the bunker, additional ARC enemies guard narrow corridors and rooms, increasing the danger during prolonged fights.
Rewards and Coin Efficiency
The primary reward source comes from the “Download Data during Hidden Bunker” objective. Eight terminals are scattered inside the bunker, each offering 800–1200 event points.
Reaching higher point thresholds unlocks better loot and double Trial Points, which indirectly improves your overall economy. Players focused on optimizing progression often compare this grind with alternatives such as best way to earn coins ARC raiders, balancing risk versus consistency.
While Hidden Bunker isn’t the fastest way to farm currency, it remains a solid cooperative event—especially for players who already prepare efficiently through platforms like EZNPC.
