Honkai: Star Rail

Honkai: Star Rail is a free-to-play turn-based RPG developed by miHoYo and published by HoYoverse, released on 26 April 2023 for PC, iOS, and Android, with a PlayStation 5 version following later that year. Set in a science fantasy universe where players travel the galaxy aboard a vessel called the Astral Express, the game draws on the broader Honkai franchise whilst telling a self-contained story accessible to newcomers. It crossed 100 million downloads across all platforms by February 2024 and surpassed $2 billion in lifetime mobile revenue by March 2025, reaching that milestone in 23 months from launch and outperforming Genshin Impact's mobile earnings across the full year of 2024.

Combat is strategic and team-based, built around a turn-order system with elemental affinities, character paths that define roles, and a gacha banner system for unlocking new characters and equipment. Monthly active users peaked at 30.1 million in February 2025, with the game generating tens of millions of dollars monthly in revenue throughout 2025 and into 2026. HoYoverse delivers regular version updates, story expansions, and limited-time events on a consistent six-week cycle, sustaining a large and active global player base across PC and mobile.
