How to Open the Hidden Bunker in Arc Raiders – Puzzle Event Trial Explained

Arc Raiders North Line update is moments away, but before jumping into the new map, there are certain new tasks players can complete for some progress. One of the new tasks is the Hidden Bunker Trials, added with the new events update. In this guide, learn where to find Arc Raiders Hidden Bunker and how to complete the new puzzle event trials.

How to Complete Arc Raiders Hidden Bunker Event

To start the new Arc Raiders Trials, you must select it while entering the Spaceport map. The Hidden Bunker is an event that only appears during select hours in the Spaceport map in Arc Raiders. Here are some important things you must remember before entering this special event map:

• During the Hidden Bunker expedition, there are fewer Return Points. This is why we suggest grabbing some better healing items and focusing on the objectives.
• In the Spaceport Hidden Bunker map, you will not find any Raider Hatches. So, avoid fighting the ARC enemies and try to go for the exit as soon as the tasks are done. Some gadgets and utilities, like Ziplines, will come in handy to quickly move across the map or even reach areas to complete the tasks.

Now that you are prepared for the Hidden Bunkers, here is how to open them in Arc Raiders and find their location.

1. How to Activate Antennas in Arc Raiders

To open the Hidden Bunker in Arc Raiders, you must locate four Antennas and activate them. You can simply locate them through a white ‘satellite’ symbol. These locations can change, so keep up with the locations every time you load into a new event. Here is the map showing how the Antenna locations look in Arc Raiders:

To activate the Antenna, go near it and hold the E button to ‘establish connection’. Once you do so, an army of ARCs will swarm the area. You can either go into attack mode or just hide before the first process is settled.

Now go back to the Antenna again and press the E button again. Repeat this process for all the other Antennas on the map. Once you activate any of the four Antennas, a server-wide notification will pop up. This will alert all the other players on the map. So, make sure you have enough Arc Raiders weapons to fight back.

2. Arc Raiders Hidden Bunker Location

After completing all the Antenna tasks, the Hidden Bunker entrance will open on the Spaceport map. There are two fixed locations to enter it, so finding it will not be that difficult. However, given that the full server already gets alerted, expect some serious arson from the ARCs and human enemies in the area. Having some durable Arc Raiders shields is the only way to visit this place.

That said, here is the Arc Raiders Hidden Bunker location: there are two entrances between Fuel Lines and Fuel Processing. Both are, of course, “hidden”. That means you might need to look around the rocks, stones, and sand to find them. One closer to the Departure Building is much harder to locate. So go for the one on the south, you will find it right around a rubble.

3. Download and Retrieve Data Inside the Hidden Bunker

That is not the end of the event. To complete the Hidden Bunker puzzle event trials in Arc Raiders, you must interact with the data terminals. There are a total of eight data terminals inside the bunker that look like old PCs. You can identify the working ones by finding a light above it. Go near these PCs and hold E to retrieve data.

Once you do it, you must stay near it to complete the process. In case you go too far, you must revisit the terminal and do the process again. We suggest you go for the strategy of two players defending the room while one completes their task.

That is how you can find and open the Arc Raiders Hidden Bunker and complete the puzzle event. Completing the trials gives you a lot of EXP and progress toward the trials rank. Did you unlock the bunker yet? Let us know in the comments.
