Well, I looked a while and didn't find a COMPLETE english translation. I downloaded BFB English Campaign v2 and it's pretty much all in Russia except for a few things. Idk if I'm doing something wrong here, but that's pretty much it.
Atm I'm playing it in Russian, perhaps I'll learn a bit
being a huge USSR fanatic I guess it adds a bit of emotion and immersion to it.
EDIT: Well, I believe I had to go into "American Campaign" to get the translated version. But when i lauch it, the games instantly crashes.
