Development and release
The game was first drafted by Kinoko Nasu under the working title "Fate Online Project Reboot",[10] which was meant to be a massively multiplayer online game using designs, drafts and concepts later collected in the Fate/complete material IV Extra material book. But the planned game was cancelled and shelved during planning stages. It later became a novel, Fate/Apocrypha, which integrated some concepts of the planned game. Later on in 2014, Aniplex proposed Nasu to revisit the cancelled game project, announcing a collaboration with the game studio Delightworks to rework the concept into a mobile RPG game.[11][12]
The game was published by Aniplex and was released in Japan on 29 July 2015, on Android devices, with a subsequent release on 12 August for iOS devices. Maaya Sakamoto performed four theme songs for the game: "Shikisai" (色彩), "Gyakko" (逆光), "Yakudo" (躍動) and "Tokei" (時計). Aside from its gameplay and own storyline, the game also features events for players to obtain new items and servants, such as summoning campaigns for limited Servants/Craft Essences, specific Servant-based events, real-world annual events, and collaborations with other Type-Moon works such as The Garden of Sinners and Fate/Zero.
On 1 January 2017, a sub-sequel to the main storyline was announced with the same title containing a subtitle named "Epic of Remnant". On 16 April 2017, Aniplex of America announced Fate/Grand Order would be released in the United States with a Summer 2017 release window. Director and Creative Producer Yosuke Shiokawa explained that while the game was intended to be released only in Japan, the team took notice of the large number of overseas players accessing the game and made a decision to make it accessible to other regions as well. Since the game's release to North American servers, it has followed behind Japanese servers by almost exactly 2 years, the same gap between launches in the two regions.[5]
On 26 December 2017, the official website and the Twitter page of the game teased the game's sequel by changing it into a "hijacked account and site". The sequel's subtitle, "Cosmos in the Lostbelt", was announced on 1 January 2018. The sequel was officially released as an expansion to the main game on the Japanese server starting in Spring 2018. On 20 April 2018, it was announced that the North American server was made officially accessible in Australia, Philippines, Singapore, Thailand, and Vietnam.[13]
On 15 December 2021, Delightworks announced that it would spin off its entire game division, including the Grand Order development team, to a new company.[14] It was established under the name Lasengle on 28 December 2021. As part of the deal, its shares were then acquired by Aniplex on 1 February 2022.[15]
On 24 February 2022, Aniplex ended services in Vietnam due to Vietnamese regulations rules.[16] On 2 August 2022, the North American server was made officially accessible to United Kingdom, Germany, France, Italy, Spain, The Netherlands, Finland, Sweden, Poland, Switzerland, Austria, Ireland, Belgium, Norway, Denmark, Portugal, Mexico, Brazil, Chile, and New Zealand.[17]
