Honkai Star Rail is a role-playing adventure in which you can play as one of four characters. The heroes travel the world as a team. Each squad member is represented by a unique class and fights using individual abilities. An open world and various dungeons with strong bosses and valuable loot are available for exploration. The combat is represented by a turn-based system in the spirit of classic Japanese role-playing games. There are main and minor quests, as well as many random events. The plot starts from the Star Express spaceship. The characters March 7 and Dan Heng must deliver ancient relics to Gerta, but on their way they encounter smugglers from the Antimatter Legion who attack the shuttle. At this time, two Stellaron hunters Kafka and Silver Wolf arrive at the station. From this moment the main actions of the adventure begin.
