Hey there, for Episode: Heresy content, it is due to this: [quote]Due to the on-going SAG-AFTRA strike, you may notice certain voice lines being silent in-game. However, we have enabled subtitles by default for this release to ensure players do not miss any narrative content. Within your Gameplay settings, we offer a variety of customization options for subtitles to help with accessibility and general visibility of narrative content. You can alter their size, color, background, show the speaker's name, and more before the launch of Heresy to prepare for introductory sequences impacted by this change. Additionally, Heresy activities that have missing voice acting will display a warning before launching those activities.[/quote] https://www.bungie.net/7/en/News/Article/twid-01-30-25
