Honkai: Star Rail is a turn-based space-fantasy RPG. You travel aboard the Astral Express between worlds — a frozen planet locked in permanent war, a decaying luxury liner, a corporate megacity — resolving the crisis on each one as the story moves on.
Combat is party-based and turn-driven, built around breaking enemy weaknesses with matching elemental damage types, so team building matters more than reflexes. It is free to play with an optional gacha for characters and light cones, and one account carries progress across Windows, Android and iOS.
Developed by HoYoverse and published internationally by COGNOSPHERE PTE. LTD., the same studio behind Genshin Impact, on a roughly six-week content patch cycle.
