The buzz around Week 12 trials in ARC Raiders is reaching fever pitch. Agents are whispering about a treasure trove of data hidden away in the Spaceport. That’s why everyone wants to get into the Hidden Bunker.
The Hidden Bunker map condition activates a special, normally inaccessible location on Spaceport. When active, the bunker doors swing open, granting access to interactive terminals. The goal? Download enough data from those terminals to snag a three-star rating.
This guide lays out the process step-by-step.
Gaining entry to the ARC Raiders Hidden Bunker
Ever been locked out of your own house? Frustrating, right? The Hidden Bunker is like that, only the stakes are a bit higher. The doorway, marked on the image below, remains sealed until you activate four antennas scattered around Spaceport. Keep your eyes peeled for white radar symbols when the Hidden Bunker map condition is live.

While a solo run is possible, think of it as trying to juggle chainsaws; a three-person team makes the task far less deadly. The bunker needs all four antennas online, regardless of who flips the switches. Once that door hisses open, everyone in the lobby gets the memo.
What are the best team compositions for clearing the Hidden Bunker?
Balance is key. A good mix includes one player focused on crowd control, another specializing in heavy damage against ARCs, and a third providing support and hacking assistance. Consider loadouts that prioritize both firepower and mobility, because standing still is a quick way to get eliminated.
Downloading data within the Hidden Bunker
Inside, it’s a race against time (and other players). Find an un-tapped terminal and initiate the download sequence. Remember dial-up internet? It’s a bit like that. You’ll have to babysit the process for a few nerve-wracking seconds until it wraps.

Repeat until you’ve secured all three stars. One word of warning: the Hidden Bunker is crawling with ARCs and rival agents. Deal with the ARCs swiftly, and consider a temporary truce with other players unless you prefer all-out mayhem.
What happens if another team steals my download?
Unfortunately, data theft is part of the game. If another team swipes a terminal you were using, you’ll have to find another. This is where teamwork and communication become invaluable. Coordinate with your squad to secure multiple terminals simultaneously, reducing the risk of interference.
How often does the Hidden Bunker event appear on Spaceport?
The Hidden Bunker event rotates, but its frequency is influenced by player activity and developer-initiated events. Keep an eye on official ARC Raiders announcements and community forums for clues about upcoming schedules. Being prepared is half the battle.
