Honkai: Star Rail (Chinese: 崩坏：星穹铁道; pinyin: Bēnghuài: Xīngqióng Tiědào; lit. 'Collapse: Starry Sky Railway') is a role-playing gacha video game developed and published by miHoYo (with publishing outside mainland China under Cognosphere, d/b/a HoYoverse). It is miHoYo's first turn-based game, featuring the main character, who is referred to as the Trailblazer, travelling across worlds through the Astral Express to help and connect the worlds while resolving disasters caused by "Stellarons" and other third-parties. The first closed beta test was launched on October 27, 2021. It was publicly released internationally on April 26, 2023,[3] for Windows and mobile devices. Additionally, the PlayStation 5 port was released on October 11, 2023. The PlayStation 4 version is still yet to be announced, as revealed at the latest Summer Game Fest with a trailer.[4] It is the fourth installment in the Honkai series, utilizing some characters from Honkai Impact 3rd and some gameplay elements from miHoYo's previous action RPG, Genshin Impact. Partially due to the popularity of Genshin Impact, the game had already received widespread expectations before its launch. It was nominated for the Most Wanted Game Award at the Golden Joystick Awards in 2022,[5] won the Best Popularity Award of World Science Fiction Game Annual Awards in 2023,[6] and Best Mobile Game Award in the Game Awards 2023.
