The “Download Data during Hidden Bunker” trial in ARC Raiders takes place on the Spaceport map and is active for only an hour at a time. To obtain the best rewards, you need to get a 3-Star Rating when participating in the Trial. This Trial generally starts at 5 a.m. EST, 2 p.m. EST, and 11 p.m. EST, so you need to be ready. If you’re not sure how to go about obtaining a 3-Star Rating and completing the Trial successfully, here’s what you need to do in ARC Raiders.
Activate Four Antennas on the Spaceport Map

To unlock the Hidden Bunker and download its data, you need to activate four Antennas around the Spaceport map in ARC Raiders. They are indicated by four “Antenna” icons on your map. Since their spawn locations vary every match, you need to open your map and check for the “Antenna” icons. Generally, each of these Antennas spawn at the north, east, south, and west, and they’re easy to locate on the map.

They spawn on rooftops, so once you locate them, you need to interact with the terminal at their base. After that, multiple ARCs, specifically Wasps and Hornets will spawn, and you need to take them out. When all the ARCs are defeated, interact with the terminal once again to activate the Antenna, which will send a signal to the entire lobby. Now, do not worry, since players will more or less help you in completing the Trial rather than hunting you down.
You don’t need to activate all four Antennas yourself. Even if random Raiders activate all four Antennas, it will still count towards opening the Hidden Bunker.
Head to the Hidden Bunker

The Hidden Bunker is located between Fuel Processing and Fuel Lines, at the bottom of the Departure Building on the Spaceport map in ARC Raiders. After activating all four Antennas, head to the Hidden Bunker, whose spawn location stays consistent in every match. Look out for Bombardiers and Bastions patrolling the area.

Before you enter the Hidden Bunker, clear them out; otherwise, you’ll have trouble in downloading the data. Don’t worry about other players, since they’re most likely to be friendly and after the same thing: downloading the required data from the Hidden Bunker to get a 3-Star Rating. Rather, team up with them and take out the Bombardiers and Bastions outside, along with Fireballs and Pods inside, to grant safe passage for all in ARC Raiders.
Download Data From Five Terminals Inside the Hidden Bunker

Next, download data from five terminals scattered throughout the Hidden Bunker in ARC Raiders. Inside the Bunker, look for the terminals that have a beacon light on them. The color can be either red, yellow, or green, and here’s what they indicate:
- Red Beacon: Data is ready to be retrieved, or it has been retrieved, and Raiders need to wait for a few seconds before they can download it again.
- Yellow Beacon: Data download is in progress.
- Green Beacon: Data has been downloaded and is ready to be retrieved.
After starting the download process, stay close to the terminal; otherwise, it will cancel the download process. Each time you retrieve data from a terminal, you get 800 Points, and you need a total of 4,000 Points to get a 3-Star Rating for the “Download Data during Hidden Bunker” Trial event. This means you need to search for five terminals inside the Hidden Bunker, then retrieve data from them to accumulate a total of 4,000 Points in ARC Raiders.
Similar to the Antennas, if other players have already started the download process, you can simply interact with that terminal after the beacon light turns green to retrieve the required data. Look around for more terminals to extract data, and keep track of the ones you’ve already retrieved data from. Chances are, other players will be extremely friendly during this event, meaning you’ll work together for the greater good, i.e., completing the Trial for everyone in ARC Raiders.
Once you’ve interacted with five terminals and retrieved the data from them, you can return to Speranza Base in ARC Raiders. Getting a 3-Star Rating in the “Download Data during Hidden Bunker” Trial guarantees epic loot, so it’s well worth going through the herculean effort to retrieve the data.
Tips to Get a 3-Star Rating in the “Download Data During Hidden Bunker” Trial
Here are a couple of tips and tricks to obtain a 3-Star Rating when participating in the “Download Data during Hidden Bunker” trial in ARC Raiders:
- Go Solo: Participating with a squad leads to chaotic PvP mayhem. Instead, go solo and start activating the Antennas, then move on to the Hidden Bunker, and start the download process. In Solo mode, players are more friendly and will actually help you out in taking down ARCs around the Antennas and Hidden Bunkers. Simply speaking, you’ll have your work cut out for you.
- Activate Antennas Early On: To get the most out of the “Download Data during Hidden Bunker” Trial, start activating Antennas early on during your expeditions in ARC Raiders. You must be quick since this event is active only for an hour at a time. Activate the Antennas and pray that the other players are doing the same, and chances are, they will.
- Gear Up: Before you start activating the Antennas then moving on to the Hidden Bunker, make sure you gear up a bit, since you’ll have to deal with multiple ARCs around these areas. However, you’ll most likely receive help from other players trying to complete the Trial as well.
- Retrieve Data From Eight Terminals For Most Points: Even though you only require 4,000 Points to obtain a 3-Star Rating in the “Download Data during Hidden Bunker” Trial, you can aim for higher by downloading data from every terminal inside the Bunker. There are a total of eight terminals inside the Bunker, and each will give you 800 Points. The more Points you can farm, the better rewards you’ll get.
