The game was developed by a core team of about twelve people. The game's universe is heavily influenced by
Mamoru Oshii's anime film
Ghost in the Shell, with some additional influence from
Akira and the works of
Kenichi Sonoda. The original plan was for Konoko to be a cyborg like
Ghost in the Shells Motoko Kusanagi. The explanation for her superhuman abilities was changed to be more organic with the addition of the Daodan Chrysalis concept by design lead Hardy LeBel.
Oni was originally expected to be released in the fourth quarter of 1999. Advertising was targeted towards that shipping date, and the game won E3's
Game Critics Awards for Best Action/Adventure Game in 1999. However, development difficulties caused the release date to be pushed back continuously. The acquisition of Bungie by Microsoft in 2000 then led to the transfer of the
Oni IP to Take-Two Interactive (which owned 20% of the studio prior to Microsoft's acquisition). Since Bungie's employees were moving to the new office location in Microsoft's headquarters or leaving the company, work on
Oni had to be completed as quickly as possible. Due to a lack of time to resolve issues with the
multiplayer code and to finish the levels intended for use by multiplayer mode, this functionality was omitted from the released version. A sequel was in development at
Angel Studios for two years before being cancelled due to a lack of progress and creative direction.
Music Half of the music was composed by
Martin O'Donnell in collaboration with
Michael Salvatori. Other tracks in the game, which had already been implemented before O'Donnell and Salvatori joined the project, were composed by the music company Power of Seven, which specialized in electronic music genres such as techno and ambient. The Power of Seven team consisted of founder
Paul Sebastien, as well as composer Brian Salter and
Kim Cascone, who served as a sound designer for the game; the team had previously worked together at
Thomas Dolby's audio technology company
Headspace. O'Donnell, who served as the game's audio lead, decided to keep the tracks Power of Seven had already composed, while composing roughly the same amount of music himself. Select tracks from the game were made available on
MP3.com in 2000, a year before the game was released. A soundtrack CD of the game's music was bundled with purchases of the game at
Best Buy. ==Reception==
