performance and the number of continues. The Pandora's Box mode was created by a single programmer and it was included later in development after getting the team's approval. The team were more familiar with the Saturn hardware by this point, so Yoshida achieved technical elements that were impossible with the first game. The team received no help from Sega's technical division, and did not use any Sega-developed tools such as the Sega Graphics Library operating system; instead, Team Andromeda's programmers created their own development tools. The transition from ground to air was difficult due to only having one scrolling layer, so the team made use of camera transitions to mask the change. A notable element was the water effects, which were created using a combination of parallax scrolling and layers, allowing a look impossible on the 3D-focused PlayStation without exceeding the hardware limits of the Saturn. According to Yoshida, the team went through multiple dragon designs, with the final designs finalized by Kusunoki. The dragons were inspired by different creatures and machines from classic science fiction. The programmers kept segmented wooden fish on their desks so they could reproduce lifelike movements for creatures in the game. Iwate had to work around the Saturn's limited 3D ability when creating the models, with Suto and Nakanishi sometimes clashing with Iwate over his complex models and movements when they tried to run them on Saturn hardware. Music Rather than using prerecorded music, the soundtrack is mostly generated via pulse-code modulation by the Saturn's hardware. Music composition was led by Yayoi Wachi. Additional tracks were composed by Tomonori Sawada, Junko Shiratsu, and Teruhiko Nakagawa. In contrast to the purely orchestral and electronic score of the first game, Zwei added ethnic elements. The music also changed in that the branching path system in Zwei meant the precise scoring of the original game was impossible. Panzer Dragoon Saga composer Saori Kobayashi credited Wachi's shift away from the first game's musical style with shaping her future compositions for the series. A soundtrack album was published by PolyGram on April 25, 1996. An arrange album created in collaboration music company Cube, Panzer Dragoon II Zwei Original Arrange Album "Alternative Elements", was published by NEC Avenue on April 21. The original Japanese album was released digitally worldwide on February 14, 2018, alongside the other Panzer Dragoon soundtracks to celebrate the 20th anniversary of Saga.
