Fanatical Golden Mystery Bundle leftover Key.
I know there is actually some region restriction, like for Russian Federation, but I don't really remember them and I didn't find how to check for the restrictions for a past bundle.

However, I believe that the current Summer Bundle can give you an idea if the game is available for your region, so i suggest that you check it on the link bellow beforehand.

Good luck!
