Issues fixed[edit]

Subtitles and closed captions not working[edit]

If language that Steam client is set into is not supported by the game, no subtitles or closed captions will show at all.
Change Steam language into supported one[11]
  • Change Steam clients language into one of the ones supported by the game, e.g. English.
Copy subtitle file and rename it to match your Steam clients selected language[12]
  1. Navigate to <path-to-game>\game\hlvr\resource\subtitles\
  2. Copy desired language for subtitles e.g. closecaption_english.dat, copy it into same folder and rename it into your Steam client language, e.g. closecaption_finnish.dat if your Steam client language is in Finnish.
  3. Navigate to <path-to-game>\game\hlvr\webui\localization\
  4. Repeat the process, copy e.g. hlvr_english.json and rename copy to e.g. hlvr_finnish.json
