• If the condition looks active, queue right away because the window lasts one hour and the start time is random.

This is the simplest answer for how to access hidden bunkers ARC Raiders, because the map condition decides access.

Prep for a fight before touch objectives

Treat this as an ARC Raiders bunker enemies guide run, because can meet strong Arc units on the way, and also risk contact with hostile raiders during the push.

Go in ready, so your objective time stays safe.

• Bring a high damage weapon, because Bombardiers and Rocketeers can punish slow clears.
• Bring extra healing items, because fights can stack fast during the event window.

Do this because survival plus extraction can pay with epic loot ARC Raiders rewards.

Open the in-match map and start scanning for ARC Raiders antenna locations spaceport, because four antennas spawn in the four corners and they sit on high rooftop spots that change per match.

Keep your search simple and repeatable.

• Look for high ground and rooftop icons, then sweep corners until spot the antenna model.
• Plan a route that touches two corners fast, so another team can cover the other side during cooperative bunker runs.

Are doing antenna activation ARC Raiders work here, and this is the start of how to open bunker ARC Raiders.

Activate an antenna without losing the connection

Go to the terminal at the base of the antenna and interact once to start the secure connection.

Clear the forced defense instantly, because hornet and wasp enemies spawn on activation and they can disrupt your connection if let them live.

Finish the antenna clean with a second terminal interaction, and that second use sends the unlock signal antenna and broadcasts the activation to the match.

Repeat this on more antennas, because the bunker needs multiple activations when other raiders do not cover their corner.

Move to the ARC Raiders hidden bunker location in the bunker southwest spaceport corner, and use your ARC Raiders spaceport hidden bunker map view to line up Fuel Processing and Fuel Lines.

Use the terrain clue that always shows on the map.

• Find the three parallel light gray paths between the fuel processing area and the fuel lines area.
• Take the middle path for the main entrance, because it is the direct line into the bunker interior.

Slow down at the door because Arcs can guard the entrance zone.

Use the alternate entrance when the main door is hot

Switch to the alternate bunker entrance at the eastern end of the south path when the main approach looks risky, and both routes still lead to the same interior area.

Respect the outside guard pack.

• Watch for Bastions and Bombardiers near the entrances, because they can lock the area fast.
• Push with stealth timing, or push with a quick clear, based on what see in front of the door.

Keep a flashlight ready, because arc enemies inside bunker space can include Fireballs and Pods and need safe visibility.

Switch objectives to ARC Raiders bunker terminals data, because the goal inside the hidden bunker ARC Raiders run is collecting data from eight terminals across the facility.

Use the layout rule so your path stays simple.

• One terminal sits on the top floor.
• Seven terminals sit on the lower floor.

Read beacon light colors, because the red yellow green terminal state tells the exact action.

Treat this as data terminals bunker management, so avoid wasting time on already-used stations.

• A terminal gives data once per match, so remember which ones already finished.
• Can let another raider start a download, then wait for green and take the data, which fits cooperative bunker runs well.

Leave the facility after collect your target data, and focus on a safe exit line because the bunker extraction loot only matters after a clean extraction.

Get ARC Raiders hidden bunker rewards mainly from completing the steps and extracting safely, with epic tier loot as the main payoff mentioned in the event description.
