@TSource Engine Query Check steam folders. steamapps/common or steamapps/music , or at the short end, steam library soundracks. Is anything there?
How was the OST even advertized? Did they promise flac album or just an in-game jukebox? 

 @09df0a19 well, it was advertised as an in-game jukebox. So they didn't lie, but I hoped for the best.

And yeah, I checked these folders. Nothing there. 

 @TSource Engine Query Then you might as well return it and sail the seven seas for flacs :trollfancy: 

 @09df0a19 nothing there. I will either try to find the tracks in the game archives, as @翠星石 suggested, or wait if somebody will rip the CD from the collector's edition and upload it. 

 @TSource Engine Query It just released so no wonder it's not there yet. CD rip might as well end up there 

 @09df0a19 I will bother after I will finish it. :)
