Honkai: Star Rail Version 4.5 Launches August 26 with Zenless Zone Zero Crossover Teased

Honkai: Star Rail Version 4.5, officially titled 'To Roll the Stars in Astropolis,' is scheduled to launch on August 26, 2026. The date comes alongside a preview stream that spent as much time pointing to the future of the franchise's family tree as it did the upcoming patch. Sharing a corporate umbrella means never having to look very far for a guest star.

According to the developer's preview broadcast, players can expect a future crossover with sibling action-RPG Zenless Zone Zero. While HoYoverse stopped short of sharing specific timelines or gameplay details, the teaser establishes a direct link between its two popular modern RPGs.

Additionally, the stream teased a hardware crossover, confirming a future collaboration featuring new Moondrop headphones.

The details

• Release date: August 26, 2026
• Update title: 'To Roll the Stars in Astropolis'
• Confirmed teasers: Zenless Zone Zero crossover, Moondrop headphones collaboration

Merging universes is a time-honored way to keep players from looking outside the corporate garden. For a community already juggling multiple daily log-ins, the upcoming crossover ensures that even when players switch games, they are still technically playing in the same sandbox.
