I seriously don’t understand why I can’t have my UI in my native language (Italian) and the dialogues in English, just like every other Halo game I’ve played. It gets even weirder when I select English as UI language but… dialogues stay in Italian.
This means that, barring a change, the only way I can have the original dialogues is… changing my Xbox language from system settings, and I frankly am not enthusiastic about it.
