The Hidden Bunker in ARC Raiders pops up only in the Spaceport region. When it starts, players drop in and search spots of interest for antennas. Turn them on to open the bunker door on the map's edge. Inside are solid loot items that Raiders grab and battle over.

After turning on four antennas, go to the Hidden Bunker entrances in Spaceport and head inside. Expect weapon crates and loot containers. Keep in mind this spot turns into heavy PvP area, so check corners carefully.

Inside the bunker, eight consoles let you download data. Find one like the one pictured and begin the download. Stay in range during it. Yellow light means download active; red light means it's cut off.

When finished, a green light shows up. Grab the data for 500 XP plus stars toward ARC Raiders week 5 Trials.
