W gothic.ini

w jaki sposób można się dostać do tego "VoiceVolume=-1" chciałbym podgłośnić

This plugin's settings menu supports german, russian, polish and english, for any other language it should display it in english.
You can change it in SystemPack.ini, just change Language in [CORE] section to ENG or something else (languages supported by union: RUS, ENG, GER / DEU, POL, ROU, ITA, CZE, ESP)

i have not found an option to change the language xD

Why you use german language then?
Aus - Off
Ein - On

I dont understand the options
Wtf is AUS and EIN

There should be in-game menu

Could you add union-menu ingame settings?
