Zenless Zone Zero update 1.7 patch notes: English VAs for Koleda, Grace, and Rina replaced

HoYoverse has published Version 1.7 of Zenless Zone Zero on PC, PS5, iOS, and Android – the Xbox port is coming with ZZZ 2.0 in six weeks – on April 23, 2025. Aside from bringing Vivian to the game and continuing to tell the story of Mockingbird, ZZZ 1.7 replaces the next round of VAs from the English dub: Koleda, Grace, and Rina have received new voices.

All of the developer’s games suffered from having to mute a lot of characters in the past couple of months due to the ongoing SAG-AFTRA strike, but it looks like HoYoverse and the recording studios it’s working with finally have run out of patience. Since the beginning of the year, voices have been replaced more aggressively in Genshin Impact, Honkai: Star Rail, and ZZZ in order to bring the games’ story presentation back up to speed.

While public perception of the strike was thoroughly positive at first with gaming communities being in support of its official goals – to enhance AI protections for VAs – the mood shifted in recent weeks after some striking union VAs publicly attacked the non-union VA who took over the role of Kinich in Genshin Impact — who, it must be noted, doesn’t even live and work in a country where SAG-AFTRA is present. More fans now believe that the union is merely making a power play to try and force many independent VAs under its banner by getting companies to sign its strike-ending interim agreement, which disadvantages non-union talents and pressure them to join SAG-AFTRA. 

For this reason, the reaction to VA replacements – previously a hot topic – is quite neutral among players, many even welcoming them.
