[SPOILERS for Survival Mode Gameplay!]
Below you'll find a list of locations in The Long Dark's Survival Mode. We hope these might be useful to you in completing the Faithful Cartographer Achievement.
NOTE: In v1.19 of The Long Dark, we've released a fix for an issue with the Faithful Cartographer achievement that was keeping it from unlocking for many players. The fix is retroactive but may require performing one mapping action per region to update the Achievement “checklist”.
An overview of mapped locations including maps.
Everything in this post was mapped after the 1.21 release, alas no achievement. The only thing I can think of, is a potentially missing Icon in Forlorn Muskeg. A 3rd "Icon - Leave Forlorn Muskeg" would perhaps make sense. Check out the mapping to see what I mean.
