Honkai: Star Rail, the fourth installment in the Honkai series, is an upcoming free-to-play 3D role-playing video game developed and published by HoYoverse. As a sequel to Honkai Impact 3rd, it features both brand-new characters and alternate versions of existing characters from the previous game, along with returning characters from other HoYoVerse games. This is a trend players can notice in Genshin Impact as well, with characters like Yae Miko and Raiden Shogun (Ei) essentially having their Honkai impact 3rd counterparts like Yae Sakura and Raiden Mei amongst many other.
