Keys
Keys and map-grid locations
Keys open special loot rooms. Their descriptions supply map-grid clues that help locate the destination.
Reported key and room
Read the key’s grid clue
Map letters run west to east and numbers north to south. The guide uses D7 at Imjin Farmland to explain coordinates; it is not the destination of an identified key. Read each key’s own description before planning the route.
A named example: The Chemist’s Secure Armory
The selected Legendary key describes an I4 bunker near the Haneul Nuclear Reactor boat house. Its visible controls are Secure, Drop and Ping. The tooltip gives a destination clue; the image does not show acquiring the key or opening the bunker.
Locked from inside is a different clue
The guide says a door locked from inside can have another way in.
What keys do and how to locate destinations
| Detail | Value |
|---|---|
| Function | Unlock special loot rooms |
| Location hint | All Keys have grid location in description |
| Grid | Letters west to east; numbers north to south |
| Example | D7 Imjin Farmland describes the grid, not an identified key coordinate |
| Door distinction | Locked from inside may require another entrance; not every locked door takes a key |
