Confirmed Language Count
The Steam language table lists English, Simplified Chinese, French, German, Spanish from Spain, Russian, Japanese, Traditional Chinese, Brazilian Portuguese, Korean, Italian, Thai, Vietnamese, Portuguese from Portugal, and Latin American Spanish.
Audio vs. Text Support
Only English and Simplified Chinese currently carry checkmarks for full audio. All 15 languages are marked for interface and subtitles. This distinction matters because a supported menu language does not automatically mean dubbed dialogue.
What Still Needs Release Testing
The listing does not explain whether language packs require separate downloads, whether voice and text can be selected independently, or whether every cinematic has matching subtitle options. Those settings will be checked on PS5 and PC after launch.
Verification Note
This answer uses the current official Steam listing. Store features can change before release, so the page records a checked date and will be retested against the October 2026 retail build.
