Looting locked rooms in ARC Raiders can be an exciting part of the game, especially for seeking the best gear and blueprints. With so many different key rooms available, it can be difficult to know which ones truly deliver great value for the effort and risk.

ARC Raiders Locked Room Tier List (Loot & Location)
In ARC Raiders, locked rooms are scattered across the map, each requiring a unique key card (green, blue, or pink rarity) to access. These rooms are typically loaded with high-value loot, ranging from weapons and attachments to healing items, blueprints, and rare trinkets. The loot varies between day and night raids, with night runs often providing a noticeable boost in both quality and quantity.
