Hypergryph Network Technology Co. Ltd. (Chinese: 鹰角网络), commonly known as Hypergryph (HG), is a video game development company based in Shanghai, China. It is known as the creator and developer of Arknights and the publisher of the game's original Chinese version.


Hypergryph was founded on January 24, 2017 by Hai Mao and his colleagues from Yostar and MICA Team (now Sunborn), the latter of which is notable for being the developer of Girls' Frontline. Most of them, including Hai Mao himself, are the alumni of China Academy of Art; later on Hypergryph also hired former members of Massive Black and Cygames branches in mainland China. Early after their foundation, Hypergryph started the development of Arknights, which is the first video game they developed before Ex Astris.

Hypergryph was originally headquartered at 700 Yishan Road on Xuhui District, which is in the same avenue as miHoYo's headquarters – notable for being the developer of Honkai Impact 3rd and Genshin Impact. In 2020, the headquarters are moved to an underground basement in Changhui Mansion at 799 Yinxiang Road on Nanxiang Street of Jiading District; the new headquarters included resting areas and a quarantine room made due to the COVID-19 pandemic.

The following part lists some notable events within the companies:

  • On June 7, 2021, Hypergryph joined the Anti Internet Backlash Alliance (Chinese: 反网络黑灰产联盟) in Shanghai alongside miHoYo, TapTap, and Shanghai Lilith Technology Co., founded in response to the various backlashes started by the rampant "keyboard warriors" and "toxic" fandoms on the Chinese internet in order to prevent such occurrences from happening again in the future as well as setting up a proto-type of game-rating, a system that is currently not yet implemented by the government.[1][2]
  • On September 2021, Hypergryph announced the development of Ex Astris, a third-person single-player action RPG (with the gameplay inspired from Valkyrie Profile) and the first game developed by Hypergryph that does not follow the free-to-play model, as well as their first game that is to be released simultaneously worldwide.[3]
  • Ambience Synesthesia marks the first offline event of Hypergryph though it is considered to be under the wing of Monster Siren Records. On November 2021, Terra Discovery Society was held in Shanghai as a small convention with Arknights' fandom creators.[4]
  • Like other gaming companies, content leaking is also an issue for Hypergryph. Starting from A Walk in the Dust, some leaked news had circulated among social platforms, especially Baidu Tieba. In March 8, 2022, Hypergryph finally took action by suing one of their employees who was responsible for the leakage.[5]
  • In March 16, 2022, Arknights: Endfield, a spin-off of Arknights, was announced. A concept trailer and gameplay vertical slice were revealed on March 18.

  • Hypergryph's Chinese name translates to "eagle horn", referring to their logo.
    • The name and logo itself are based on the hippogriff, also spelled hippogryph.
  • The Arknights community jokingly believes that Hypergryph is in fact a music company due to the game's background musics/BGMs, Operator leitmotifs, and songs related to the game which came in a wide variety of genres.
    • An actual live concert featuring the game's songs, Ambience Synesthesia, cemented this belief.
    • The CN community takes this further by calling HG "Musicgryph (音角)" instead, which is a pun to the hanzi for "eagle" (鹰; Pinyin: yīng) that are pronounced similarly to the hanzi for "music" or "sound" (音; Pinyin: yīn).
  • Due to their unnecessary verbous text in their stories cut-scenes, the CN community often jokingly calls it as "Hypergryph's language (鹰语)."
  • Hypergryph has an official mascot named Miss Hypergryph (鹰小姐), appearing as a cold yet funny office lady with white, long hair and black horns. She is described to be in charge of the official Sina Weibo accounts of HG and CH.O 3.
    • In April 26, 2020, Miss Hypergryph accidentally posted the advertisement for an Arknights merchandise using HG's account instead of CH.O 3's. This caused the CN community of Arknights to jokingly refer to Miss Hypergryph as a cute but clumsy lady.
    • Recently, Miss Hypergryph has also received a overhauled design, which can be noticed through their Weibo posts in CH.O 3's account.
    • The Global server replaces Miss Hypergryph by a chibi bunny that resembles Amiya.
