This was originally posted on the official Alien: Isolation forum, but that has been down for a few weeks now, so I'm putting up a mirror here.
I made maps for all the Survivor Mode levels, since the game doesn't provide one for you. The maps are just pencil and paper for now. If I ever get the time, I'd like to redo them with proper graphics.
Corporate Lockdown (Severance, Scorched Earth, Loose Ends):
Trauma (Reoperation, Crawl Space, Overrun):
The Trigger (Damage Control, The Package, Blast Seat):
Edit: Put AstalaYstalawa's maps on top
There are actually very detailed maps on steam http://steamcommunity.com/sharedfiles/filedetails/?l=czech&id=371906352
Those look very nice indeed :)
Edit: With kind permission from AstalaYstalawa, I'm putting up a mirror of his versions of the maps here.
He also has maps of the main campaign and Nostromo DLC with additional information compared to the in-game maps: http://steamcommunity.com/sharedfiles/filedetails/?id=371906352
