Silas found a corrupted hard drive. It wasn't weapons or food; it was a massive digital archive of translated military protocols and civilian distress signals in twenty-three different languages.
Copy only the language-specific files into the corresponding directories in your install. For example, to add German:
Copy ...\addon\German\BendGame\Content\Audio\VO_German.bnk to \Days Gone\BendGame\Content\Audio\.
