The ARC Raiders Red Room is a secret location in Reinforced Reception on Blue Gate. The room contains valuable loot such as blueprints, crafting materials, high-tier equipment, and weapons.
Let’s see what you must do to solve the Red Room puzzle and unlock the door!
How to Find and Unlock the Secret ARC Raiders Red Room
The Red Room is a locked chamber beneath Reinforced Reception. Make your way to the location and enter the building.

As soon as you enter, you will notice two ziplines. Take either one and descend. Proceed to the main hallway. If you follow the blue line on the floor you will discover the Red Room entrance.

However, don’t go there just yet as you need three batteries/fuel cells to unlock the door.
Where to Find the Batteries to Solve the Red Room Puzzle
From the main hallway, follow the blue and red lines up to the point where you see the L/R markings on the wall.

Go left, following the red line, and you will reach a battery dispenser under the stairs. Take one battery and follow the blue line that leads to the ARC Raiders Red Room entrance. Interact with the machine and place the fuel cell in the slot. You need to find three batteries to unlock the door.

There are several locations where you can find these batteries. From the dispenser machine location, take the stairs up and you might find one near the door. You can also find them downstairs, in the chamber to the left, on the way to the Red Room. Sometimes, a battery will spawn just near the Red Room door.

You need to carry the batteries to the door one by one. They hinder your movement and make you vulnerable, so make sure you clear the area first and be wary of other players. Another thing to keep in mind is that the door can be locked from outside, meaning that other players can trap you inside.
