ARC Raiders' newest map, Stella Montis, has several areas that require a key to access, and the Archives room can help you out with some incredible rewards.
The room will be initially locked when you first come across it in Stella Montis. Once you have the key, you can unlock the door and loot as many items as you can (and want). This guide will tell you where you can obtain the key and where to use it if you manage to get lucky.
