Honkai Impact 3rd (aka Benghuai 3rd or Houkai 3rd) is the Spiritual Successor to Guns Girl Z (alternatively known as Honkai Gakuen 2), developed by miHoYo. It is also their third entry in the Honkai Gakuen universe. It was released first in China in 2016, in Japan and Southeast Asia in 2017 and globally on March 28, 2018 for iOS and Android. A PC port with cross-play capability was later developed and was released globally on December 26th, 2019, with Southeast Asia getting it in 2020.
The story follows the escapades of the "Valkyries" of the Schicksal Organization, groups of female fighters who fight against the phenomenon called "Honkai"note and its manifestations, mainly in the form of zombies and Honkai Beasts. They also clash with a rival organization named Anti-Entropy (aka "Negentropy") who are also fighting the Honkai phenomenon but have different agendas and use different methods.
In-game, you take the role of "Captain" of the flying battleship Hyperion, your Valkyries' home base, and you'll be tasked with managing the Valkyries and completing missionsnote . The gameplay follows a 3D Beat 'em Up format (similar to PlatinumGames works) in which you can deploy up to 3 characters in the levels, along with a simple but powerful control system. The game's content features a Story mode, which is essentially the "main" game; a number of side missions which allow you to earn coins, materials, upgrades for the Valkyries, and other rewards; and occasional events and quests which often contain RPG and Visual Novel elements.
Honkai Impact also includes supplementary comics and Visual Novels that can be found on the main Chinese website. Official English versions of the comics are posted by miHoYo on their Global website for mobile phone users, and on Mangadex for those that prefer a PC-accessible version. Second Eruption also has a page on this site. Some of the game's animated scenes have also been posted outside the game, such as the "Reburn" video, along with CGI-animated videos that correspond to parts of the story but don't appear in-game.
Starting from June 28, 2019, a Slice of Life short animated series titled Cooking with Valkyries (an adaptation of one of the Spin-Off comics) was released on the official YouTube channel, with a second season airing in Summer 2020.
