Zenless Zone Zero's Version 1.5, titled "Astra-nomical Moment," launches January 10th at 7:30 PM (UTC+8). This update introduces S-Rank characters Astra Yao and Evelyn Chevalier.

Building upon the significant improvements of Version 1.4 (released December 18th, 2024), which included the highly anticipated character Hoshimi Miyabi and streamlined agent leveling, Version 1.5 promises even more. Version 1.4 also saw the addition of the free S-Rank agent Harumasa and refinements to the Inter-Know journey system.

HoYoverse's social media announcement confirms a special program livestream on January 10th at 7:30 PM (UTC+8). This livestream, following the format of previous events, will likely showcase a new trailer, gameplay featuring Astra and Evelyn, and a preview of upcoming content. Expect a redemption code offering in-game rewards like Dennies, upgrade materials, and Polychrome.

Recent leaks suggest Version 1.5 will include a "Bangboo Beauty Contest" event allowing players to customize Eous' appearance, potentially unlocking a new skin for Nicole. Further details regarding additional features and game modes are anticipated during the livestream.
