What to know

  • The trial only progresses during the Hidden Bunker map modifier
  • You must activate antennas before the bunker opens
  • Downloads come from terminals inside the bunker
  • Multiple downloads are needed to secure three stars

In ARC Raiders, Season 2 Week 4 introduces a trial that pushes you into one of the game’s riskier PvE objectives. “Download information inside the bunker” is tied entirely to the Hidden Bunker world event, meaning preparation and timing matter more than raw combat skill.

If you approach it methodically, you can clear the objective and secure three stars in a single run.

How the Hidden Bunker works during Week 4

The Hidden Bunker is a conditional map modifier. If it does not appear when you deploy, the trial will not track progress at all. When active, the map spawns several antenna or scanner consoles that must be activated to unlock the bunker entrance.

ARC Raiders: Hidden Bunker Location Guide
The Hidden Bunker is a sealed underground structure in ARC Raiders containing high-value loot, crafting items, and rare materials. This guide explains where to find it, how to enter it, what you’ll find inside, and the best tips for farming it efficiently.

How the Hidden Bunker works

Location for the Hidden Bunker on Spaceport

On Spaceport, the hidden bunker is near the Departure Building. It is usually accessed through a sealed underground structure that only opens after all antennas are active. The interior is compact, with limited cover and predictable enemy spawns, making it one of the more dangerous download locations if other players arrive mid-event.

How to complete the bunker download trial

Step 1: Load into a run with the Hidden Bunker modifier

Before committing gear, confirm the run includes the Hidden Bunker condition. If it is not listed, extract early and redeploy rather than wasting time.

Step 2: Locate and activate all antenna consoles

Move between the marked antenna or satellite terminals across the map. Each one must be interacted with until its activation completes. Expect enemy patrols and occasional player interference while doing this.

Step 3: Reach the newly unlocked bunker entrance

Once all antennas are active, the bunker door unlocks. On Spaceport, this is usually underground and clearly marked once accessible.

Step 4: Enter the bunker and find download terminals

Inside the bunker, you will find computer terminals positioned along corridors or rooms. Each terminal allows a data download interaction with a visible progress bar.

Step 5: Complete all required downloads for three stars

One download advances the trial, but full three-star completion typically requires interacting with multiple terminals. Move carefully between them and finish every available download before extracting.
