Honkai Impact 3rd () is a 3D free-to-play action role-playing mobile game. It was created by Chinese developer miHoYo. The game's story is set in an alternate version of Earth, plagued by catastrophes resulting from a mysterious supernatural force called "Honkai" (in Chinese it translates as "Chaos", while in Japanese, it is spelled as "Houkai"). It is the third entry in the "Honkai" series and spiritual successor to "Honkai Gakuen", using many characters from the previous title in a separate story.
