How to open the hidden bunker in Arc Raiders?

Arc Raiders has much for players to explore and discover, despite having a limited number of maps. The game quickly became a hit among fans of extraction shooters, and it’s no surprise why. Naturally, players have to discover a handful of things themselves, including where to find the hidden bunker.

The hidden bunker requires players to first activate the antennas, which open the said bunker. These bunkers only spawn during raid-wide events, and knowing where to find them on the west side of the map, just near the fuel processing POI, is key to getting there before other players.

So, if you’ve been attempting to locate and open the hidden bunker in Arc Raiders, keep reading because we have you covered.

How to activate the antennas to open the hidden bunker in Arc Raiders?

To unlock the hidden bunker in Arc Raiders, players must start a match on the Spaceport map when the hidden bunker condition is active. Opening the map reveals four antenna icons around the area. These antennas are essential because activating all four is the first step to revealing the bunker’s location. A single player or team doesn’t have to activate every antenna. Different raider teams can work on different antennas simultaneously, and an announcement will notify everyone once all antennas have been activated and the bunker is accessible.

Players will find a terminal at the base of an antenna. Interacting with this terminal begins the activation process, but it summons ARC enemies like hornets and wasps that players must defeat. After defeating them, the player must go back to the terminal and interact with the “send unlock signal” prompt to complete the antenna’s activation.

Some antennas are difficult to reach because they’re positioned on rooftops, so players won’t be able to get to them without items like ziplines. Areas around antennas and the bunker entrance are full of ARC enemies like bastions and bombardiers, so players must prepare with weapons, ammo, and healing items before going in.

When can players find the hidden bunker entrance on the Spaceport map?

After the raid-wide announcement informs everyone that the hidden bunker is open, players must find its entrance. The bunker is on the west side of the map, around the rocky field area that’s east of the fuel processing POI. If players zoom in on their map between the Fuel Processing and Fuel Lines POIs, they’ll see three light-gray paths. The hidden bunker is in the middle of one of those paths.

Players can go to the hidden bunker using an alternate method if they are having issues finding the main entrance. Another entrance is at the eastern side of the southernmost path between fuel processing and fuel lines. Once players are inside the bunker, they must be careful because threats like fireballs and pods can lurk nearby.

What is inside the Arc Raiders’ hidden bunker, and how do you get the data?

Players will find numerous types of weapons and ammo crates to loot inside the bunker, providing them a chance to get powerful guns and blueprints. The main objective in the bunker is to interact with eight computer terminals that are spread throughout the facility to download and retrieve data. This data retrieval is essential to complete the “download data during hidden bunker” trial, which rewards players with epic loot after successful extraction.

Players can identify terminals through a beacon light on top of them, and the light’s color shows their current state. A red light means that data is ready to be downloaded, a yellow light means there’s a download already happening, and a green light means the data is ready to be retrieved. To retrieve the data, players must find a terminal with a red light and begin the download. It’s important to stay close to the terminal while it’s downloading, or it will cancel. 

Once it’s complete, the light will turn green, and players can interact with the terminal again to “retrieve data” for a 500 XP reward. Since multiple raiders can cooperate, the player doesn’t need to start every download, but they can only get data from each terminal once. The goal is to retrieve data from all eight terminals before extracting to get the reward.
