We are working to make this option easily accessible for users. In the mean time, your language can be changed via Darktide's user_settings.config:
- Press the Windows key + R
- Enter %appdata% within the search input and select 'OK'
- Navigate to AppData\Roaming\Fatshark\MicrosoftStore\Darktide
- Open the user_settings.config
language_id = "en"to
language_id = "??"
- Change ?? to your language code, e.g. German = "de". See here under the "639-1" column to locate your language code: https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes
- Save your changes
- Re-launch Darktide
