One uh- problem (?) regarding the 'Steel Memory' achievment - I've cleared 2 successful runs without opening any of the Floor folders and surviving. One of them I used todays list, and on the second, I've did the same but without the list. Yet the achievment somehow didn't pop?
The things II *have* used is the checklist and of course the documents presented by the (not) Neighbours to identify if they're a neighbour or not.
Any help/clarification? (It could be a platform related issue/bug like usual (I'm using Mac) because I've seen others get the achievment)
