Still unable to unlock the 'This Darkened Earth" achievement, I have made sure to visit all locations many times now.
I belive all the locations will be:
Big Map:
Salt plains, Flooded town, Archeological site, Bus stop, Pond, Storm's home, Old cemetery, Memorial of the 12 and of cause The Anthill.
Small Map:
Colonel Estate, Library, Second Church, Town plaza, Tailor, P's home, Whorehouse
Yes, I visited all of the above again, since the new patch 0.6.2.1 and still didn't unlock. I started a new playthrough today to try it again.
