💳Keycard Rooms

Around the map you will come across securely locked doors blocking access to a room. To unlock these doors will require you to use the associated keycard (see above image) on it, which will grant you access to the room, as well as whatever mysteries may lie within it.

Keycards can be found around the map, predominantly in military areas. Certain events may also include them within their contents, so be sure to be on the lookout for both the cards themselves, and any dynamic events around the map!
