Are they really better than the Contact ones though? :) As a native, I can hear that their Russian is a tiny bit off, but nothing too noticable.
I think I deliberately didn't assign the voices to any identity, probably to make it more flexible for other modders.

took me long enough to find these! They're weird lol, but better than the ♥♥♥♥♥♥ Polish-Russian from Contact update. Thanks for the upload!

I'm going to try and figure out an easy way to add them to an identity like "LanguageRUS" for use with config/factions. If you want I can send the changes to you to upload.
