Would love to be able to purchase these items. Game feels kind of naked without them. Thanks...

I would love for them to come here for purchase too, but seeing as they're not available for sale anywhere, including Steam and Epic, it seems unlikely. I guess they were only pre-order bonuses.

Hello! I preordered Metro Exodus back in the day and got an artbook and OST. If you're interested specifically in these files, I can share them. That's not a problem :)
