I'm seeing a Steam guide which appears to have maps for every location in the game - but these maps appear to have been painstakingly assembled by random users.

Look at the tutorial map - then look at Fallgrim. Jesus Christ, man. The sheer amount of complexity in Fallgrim is insane - and that's where the player is thrust into 5 minutes into starting the game. Why on EARTH does this game not have a map or just a mini-map? How are you supposed to know where the nearest checkpoint is, where ANYTHING is? The visual design doesn't make it any easier either because it's just a bunch of intense fog overlaid on swamps, trees, hills ad infinitum.
