Ok!, I found a Russian download!
Fortunatly an audio russian voices is included in audio folder, I rename the original in default\audio and replace by this one, it works fine !
In Campaigne folder there is an images folder with fantastics photos too !
Be care, it's a rar file, but winrar didn't open it!?, i used 7-zip with success!
