Development of "Xenosaga Episode II" began following the completion of "Episode I". Series creator Tetsuya Takahashi gave control of the "Xenosaga" series to a new development team, resulting in a number of changes. The gameplay system was redesigned based on feedback from "Episode I". The scenario, written by Norihiko Yonesaka, was based on the original draft by Takahashi and Soraya Saga, with "Episode II" being Saga's last contribution to the main trilogy. The music was composed by Yuki Kajiura and Shinji Hosoe, who worked separately on the cinematic and gameplay soundtracks respectively.
