ARC Raiders Items features multiple maps that divide the Rust Belt into four distinct regions. If you've been playing on the Blue Gate map, you may have come across the Raider's Refuge area, which has a locked cellar door on the exterior of the building. The door has four light bulbs on it, which turn on when players press buttons scattered across the area. This guide will help you unlock the Raider's Refuge Cellar Door by detailing all the button locations for it in ARC Raiders.

Raider's Refuge is a medium loot value area located in the northwest region of the Blue Gate map. Once players arrive at the location, they'll notice a locked cellar door leading to Raider's Refuge basement, which contains some of the rarest loot (Epics and Legendaries) in ARC Raiders.

To open the Raider's Refuge cellar door, you'll need to locate four buttons hidden both inside and outside the building. The location of these buttons is randomized on every run, so the best I can do is share their most common positions, so players can have an easier time locating them all and opening the Raider's Refuge locked door.

Raider's Refuge is a hotspot for both raider and ARC Machine activity. Players will encounter multiple Rocketeers, as well as Snitches, Wasps, Hornets, Spotters, and Bombardiers. Players may also encounter a Turret inside Raider's Refuge main building, so watch out for it.

Once you've finally found four buttons, all bulbs will turn green, and you'll successfully unlock the Raider's Refuge cellar door in ARC Raiders BluePrints. Use the ladder to descend into the basement and loot cupboards, drawers, weapon cases, and other crates inside the basement to find high-value loot. Most commonly, players will find Epic crafting materials, tools, weapon blueprints, Legendary and Epic weapons, and other valuable trinkets in the basement.
