Mikhayl,
I am very glad to know that you also find the "Frontline Acustics" mod as a good workaround for the sounds-not-attenuating-properly problem
I am also very glad to see that you have found no other major bugs in Steel Fury. I think it is a really good WWII tank sim that only needs polishing as you say. Probably the "Fall Blau" add-on already developed by Graviteam will provide the polishing necessary... It is really a shame, but although the add-on was finished some months ago they have not found a way to publish it.... I hope it will be published in the near future... I am really looking forward to playing Steel Fury with its Fall Blau add-on !!
