Honkai: Star Rail’s Version 4.5 update launches on May 21, introducing Astropolis as the game’s newest region. The patch also adds two new playable characters and adjusts existing mechanics to improve balance.
Astropolis, a celestial-themed area, will feature fresh story quests and environmental challenges. The update’s character roster expands with a five-star Fire unit and a four-star Imaginary unit, both designed for varied combat roles.
Players can expect quality-of-life changes alongside the new content, including adjustments to character ascension materials and artifact drop rates. The update will roll out globally at 04:00 UTC on May 21.
