Players can access the Spaceport’s hidden bunker only after activating every required antenna on the map.
The “Spaceport Hidden Bunker” is a map modifier that forces Raiders to navigate the terrain quickly. This operation requires syncing radar dishes to unlock a secure zone filled with hostiles and high-tier loot.
Mastering the various phases of this challenge – from the antenna hunt to the final breach – is necessary for survival. Since success is difficult without cooperation – players should prepare for a significant combat trial.

Learning the specific steps to navigate the Hidden Bunker location and identify radar equipment is the first priority.
To open the vault – players must find four antennas marked by white radar icons. These appear randomly each game – but they are always found on the roofs of buildings that do not require keys for access.
Each activation triggers waves of Arc Raiders – Hornets – and Wasps. Once all four are active – a global notification confirms the bunker is open. Move quickly – or the loot will be gone before you arrive at the entrance.
Bunker coordinates and accessibility

The facility is in the southwestern corner – near the Departures building between the fuel refinery and the pipelines. Entry is possible through several main doors or a detour path further to the southwest.
The perimeter is patrolled by Bastions – Bombers – Rocketeers – and aerial units. Stealth is difficult without a photoelectric cloak – so players must bring their best weapons for the fight.
Data extraction and rewards

Inside the bunker – Raiders will find eight terminals for data extraction. To earn experience and complete “Trials” – players must stay near the consoles until the green light appears.
The vault holds weapon cases – medical bags – and grenade launchers. There is a chance to find the Vulcan blueprint in containers. Blueprints may also appear in hackable crates within Spaceport tunnels – though this is unverified.
