ARC Raiders Hidden Bunker Locations | Is This Event Still Worth Farming?

Category: ARC Raiders Posted: Jan 20, 2026 Views: 12363

Besides exploring the regular maps, various map events that spawn at any time not only feature unique terrain but also offer more loot or trial points - of course, the enemies are also more difficult to deal with.

Among all ARC Raiders map mods, Hidden Bunker is unique in that it only spawns on Spaceport map and was temporarily removed with the release of Patch 1.5.0, only to be reinstated with Patch 1.7.2.

So how is Hidden Bunker now, and does it still offer enough farming value? We'll analyze it.

ARC Raiders Hidden Bunker Locations | Is This Event Still Worth Farming?

What is a Hidden Bunker?

First, like most map events, during a Hidden Bunker, you cannot activate Raider Hatches and then use a key to leave, and the available extraction points are reduced, while the danger from enemies is greatly increased.

Furthermore, Hidden Bunker doesn't create a map-wide effect; instead, it exists as a bunker complex on the west side of Departure Building. You need to activate it under specific conditions to begin the challenge.

How to activate Hidden Bunker?

After entering Spaceport map where the event spawns, you'll see an antenna in each of the four cardinal directions (north, east, south, and west) on the mini-map. You need to find and activate them one by one through exploration.

The tricky part is that the exact locations of these four antennas change every time the map refreshes. However, regardless of the location, the antennas will always appear on rooftops, so you can use high ground to observe and search after entering the map.

Next, you need to activate all the antennas. To save time, it's best to team up and split up with your teammates to complete this step. Find the terminal at the bottom of the antenna and interact with it to activate it and connect it to other antennas.

Upon first activating an antenna, it will emit a brief alarm and spawn two specific ARC enemies, Wasp and Hornet. You must defeat them to continue the mission.

After interacting again, the antenna will be marked as complete, and all antenna unlock progress messages will be shared throughout the matchmaking lobby. Once all antennas are activated, all players will receive a message that Hidden Bunker is open.

Where is the bunker complex?

After the event is activated, you need to travel to the southwest of the map and find three paths between Fuel Processing and Fuel Lines. The bunker entrance is on the middle path. Alternatively, you can find an alternate entrance on the east side of the southern path.

The bunker entrance looks like it leads to an underground shelter. Two Bastions and one Bombardier will be constantly patrolling around it. You need to kill or avoid them to infiltrate deeper into the bunker. Enemies will also appear inside the bunker.

If you're worried about handling it alone, you can team up. However, if your teammates are strangers you've been matched with, be careful not to get ambushed. After all, ARC Raiders brings a world where the strong prey on the weak.

How do you get the event rewards?

As you enter and explore the bunker, you can obtain loot by defeating enemies or finding hidden containers. However, to unlock the ultimate reward, you must complete the specific Download Data during Hidden Bunker trial.

This trial requires you to find eight scattered terminals within the bunker complex and download and retrieve data at each terminal. Each terminal has an indicator light; you can determine its status by the light's color:

  • Red: Data has not yet been downloaded, or it has already been downloaded; you need to wait for the cooldown to finish before downloading again.
  • Yellow: Data downloading.
  • Green: Data download complete.

Similar to activating the antenna, this step is more efficient when done in cooperation with others, and Hidden Bunker event itself only lasts 40 minutes. Also, be sure to stay close enough to the terminal while downloading data, otherwise the download may be interrupted.

Each terminal provides 800-1200 event points; you earn points for each completed data download. Reaching certain point thresholds unlocks additional point rewards:

  • 1,000 Points: Uncommon rarity item.
  • 2,500 Points: Rare rarity item.
  • 4,000 Points: Epic rarity item.
  • Max Points (6,400+): Ensures you achieve the highest rewards and double Trial Points in this week's Trials.

It's worth noting that while exploring the bunker, you might find special items or markers. Some are related to puzzles that grant rewards upon completion, while others may be Easter eggs planted by the developers for future updates.

Is Hidden Bunker worth completing?

Compared to other map events, Hidden Bunker's rewards aren't particularly generous, but correspondingly, the chance of spawning high-difficulty ARC enemies is also slightly lower. This event seems to emphasize the importance of cooperation more than difficulty.

Therefore, overall, this event is suitable as a practice ground for advanced Raiders, but it doesn't present a challenge for top players who have already mastered the map event mechanic.

This concludes our introduction to Hidden Bunker gameplay and a brief analysis of its farming value. We hope this information is helpful for your ARC Raiders gameplay!
