FATAL ERROR: Can not init steam

[Mudbill]

Hmm, well that error usually appears if the Steam copy of the game is ran manually via its folder executable.

Either way this error has been popping up only recently and I believe it's an issue in one of the recent updates for Amnesia. You can try this temp fix for the time being:

You may download that "Amnesia_Retail.exe" file and place it into your Amnesia install folder. Rename Amnesia.exe that is already there to something like Amnesia_backup.exe first, then rename Amnesia_Retail.exe to just Amnesia.exe. This should replace the broken file causing this Steam error. After that, try starting it again. It should be possible by double clicking the files in the folder. I haven't tested starting it through Steam this way.
