Direct answer
Steam lists Simplified Chinese and Traditional Chinese for the Wanderburg interface and subtitles. Full Chinese audio is not listed; the language table was checked September 11, 2026.

What the Steam language table shows
Both Chinese variants have checks under Interface and Subtitles, while the Full Audio column is blank. That is narrower than claiming full localization.
Translation details remain patch-sensitive
Launch-week notes fixed Loadout and Captain localization issues, so individual labels may change even while broad language availability remains listed.
