No Dub for You: Unlike its precursorgames, many of the promotional material for Zenless's English and Korean releases only included the Japanese audio, as opposed to having all four languages exclusive to each market. This extended to even its official website; usually, most international miHoYo games since Genshin would include a feature to toggle between the Japanese audio and the dubbed audio. For Zenless, the latter audio is substituted with it's native Chinese audio. The 2023 Gamescom trailer would confirm an English and Korean dub and all of their content since then had the aforementioned languages.
Uncredited Role: Despite the game being dubbed in English and Korean, none of the voice actors for the aforementioned languages are credited in game, not even on the official trailers or website where they should be.
