I don’t have an Xbox but can someone please do it it is hard to get immersed when Chinese soldiers are speaking English or Russian. I know the Great Wall and Shanghai maps have Chinese voice lines but most don’t
It depends if the authors of those mods are willing to make that change.
You need to ask those authors for that, not just anyone, unless you are telling them to hack the author’s pc to make the change (just kidding)
I think they do pretty good Chinese voice lines in South Park.
