Hidden Bunker ARC Raiders appeared during February gameplay sessions on the Spaceport map, creating a high-risk objective that pushes squads across rooftops and underground corridors. Access to the bunker requires activation of antenna transmitters scattered across elevated structures. After the signal network completes transmission, sealed bunker doors open across the southwest area of the map.
The objective creates intense competition across the raid. Squads move quickly across rooftops to activate transmitters while defending against robotic ARC units and rival players.
Hidden Bunker Location on the Spaceport Map
The bunker sits in the southwestern section of the Spaceport map, close to industrial structures and fuel infrastructure.
Nearby landmarks help players identify the correct area.
| Location Detail | Description |
|---|---|
| Map | Spaceport |
| Area | Southwest sector |
| Nearby zones | Fuel Processing, Fuel Lines |
| Nearby building | Departure Building |
| Access | Multiple sealed bunker doors |
The terrain around the bunker features rocky ground and reinforced metal entrances embedded into the hillside.
Heavy ARC patrols guard the surroundings, making direct entry difficult before the antenna system activates.
Steps Required to Open the Hidden Bunker
Access requires several coordinated actions across the map. Players must locate and activate four rooftop antennas that transmit signals to the bunker control system.
Activation process
- Enter a raid on the Spaceport map
- Locate antenna towers shown on the map
- Travel to rooftop antenna locations
- Activate each antenna transmitter
- Defeat ARC units that spawn after activation
- Interact again to send the signal
- Repeat the process for all four antennas
After the fourth signal transmits successfully, bunker doors unlock across the map.
At that moment every squad in the raid receives access to the bunker entrances.
Antenna Locations Across the Map
The antenna transmitters appear on rooftop structures scattered across Spaceport. Each raid rotates the positions, forcing players to search elevated buildings.
Common antenna locations appear on rooftops such as:
- Departure Building roof
- Control Tower
- Maintenance Facility
- Cargo Warehouse
- Launch Operations structure
- Storage hangars
Because the locations rotate each raid, movement across multiple sectors often becomes necessary.
Enemy Threats During Antenna Activation
ARC robotic units attack players immediately after antenna activation. These enemies appear in waves and create intense rooftop battles.
Common enemy types near antenna towers:
- Hornets – fast aerial attackers
- Wasps – small drone swarms
- Bastions – armored defensive robots
- Bombardiers – explosive artillery units
Players who arrive unprepared often lose valuable equipment during these encounters.
Equipment Recommended for the Mission
Preparation greatly improves survival chances across antenna towers and bunker corridors.
Recommended loadout items:
- Assault rifles for medium-range combat
- Long-range rifles for rooftop enemies
- Shield recharge kits
- Ammunition reserves
- Explosive grenades
- Ziplines for rooftop access
Many rooftops lack ladders or easy entry points, making mobility tools extremely helpful.
Entering the Hidden Bunker
After antenna signals complete transmission, bunker doors unlock across the southwest region of the map.
Several entrances exist, allowing squads to approach from different directions. Combat frequently breaks out near these entrances because multiple squads attempt to enter at the same time.
Inside the bunker players encounter:
- weapon crates
- supply containers
- crafting resources
- underground hallways
- data terminals
The bunker interior contains several connected chambers filled with loot and defensive ARC units.
Data Terminal Objectives Inside the Bunker
Several data consoles remain scattered throughout the underground facility. Raiders interact with these terminals to begin file downloads.
Terminal lights display status indicators.
- Red light – inactive terminal
- Yellow light – terminal ready for interaction
- Green light – active download in progress
Players must remain close to the terminal until the download completes.
Enemy waves often attack during the process, forcing squads to defend the room while data transfers finish.
Hidden Bunker Loot Rewards
Loot inside the bunker ranks among the most valuable items found during Spaceport raids.
Important rewards may appear in crates and locked containers.
| Loot Category | Example Items |
|---|---|
| Weapons | rifles, SMGs, rare variants |
| Crafting resources | mechanical parts, batteries |
| Ammunition | light, medium, heavy ammo |
| Upgrade components | weapon attachments |
| Data files | mission progress items |
Risks Inside the Hidden Bunker
The bunker location creates one of the most dangerous zones on the map. Several factors increase the risk level dramatically.
Main dangers:
- multiple squads entering simultaneously
- tight corridors that limit movement
- continuous ARC enemy patrols
- explosive robots near choke points
- limited escape routes
Players who move carefully and clear each room gradually survive longer inside the facility.
Raid Conditions During the Hidden Bunker Mode
The Hidden Bunker scenario changes several raid mechanics on the Spaceport map.
| Feature | Gameplay Effect |
|---|---|
| Raider hatches | Disabled |
| Map objective | Antenna activation |
| Bunker access | Locked until signals transmit |
| Enemy activity | Increased patrols |
| Raid duration | Around 40 minutes |
These conditions increase tension across the entire raid as squads compete for bunker access.
Strategy Tips for the Hidden Bunker Mission
Experienced players follow certain strategies to increase survival chances.
Useful tactics:
- Activate antennas early in the raid
- Travel across rooftops to avoid ground patrols
- Carry additional shield packs
- Clear bunker entrances before entering
- Secure escape routes before collecting loot
- Work in coordinated squads
Movement speed and communication often decide who exits the bunker alive.

Where is the Hidden Bunker located in ARC Raiders?
The bunker sits in the southwest section of the Spaceport map, near Fuel Processing and Fuel Lines close to the Departure Building.
How many antennas must be activated to open the bunker?
Four rooftop antennas must transmit signals before bunker doors unlock.
Do antenna locations stay the same every raid?
No. Antenna towers rotate across different rooftops each raid, forcing players to search elevated buildings.
What enemies guard the bunker area?
Players usually encounter Bastions, Hornets, Wasps, and Bombardier robots near antenna towers and bunker entrances.
Can a single player unlock the bunker?
Yes. A solo player may activate all antennas, though squads complete the objective faster.
What rewards appear inside the bunker?
Players can collect weapons, ammunition, crafting materials, upgrade components, and data files from bunker containers.
Hidden Bunker ARC Raiders creates a high-risk objective across the Spaceport environment. Players activate rooftop antennas, battle robotic enemies, and descend into underground corridors packed with valuable loot. Squads that move quickly, coordinate effectively, and secure bunker rooms often exit the raid with the strongest rewards.
