can you add in your main post that in the menu where you download the game installers (don't know how it works with galaxy i don't have it) for most games you need to chose the language from the top menu. while apparently nothing happens, after that when clicking on the installers it will give you the game files for italian for example instead of english, which will have the voice overs. so for example if you want to get black mirror, the original ones in italian you have to do it like this, or for might and magic v for example

I'm sure many people have no idea about this because they are used to modern games that contain multiple languages in one installer and the language can be even switched during gameplay.

Shelter has no voiceovers at all, just badgers squeaking.
