Segawa's work, with Nishigaki mostly writing the character banter. Eliot was not written as a conventional lead, being fun-loving and flirtatious in contrast to Dogs' more traditional stoic attitude. Janine was described as central to the character drama. Commenting on the character and world design, Segawa described Nephilim as a fantastical being compared to the grounded tone of the other characters. The game featured both fully 3D graphics for its environments and character models, and a large number of CGI cutscenes. Nishigaki speculated that Sega's support of the project was due to this focus on 3D polygonal graphics. The lighting was split between three sources; Nephilim, weapon bursts, and pre-set map lighting. While the Dreamcast was reported to refresh at 60 frames per second, Blue Stinger was kept to 30 due to the number of creatures shown on screen. They also did not use some of the graphical elements the console was capable of such as bump mapping. During development the team did not know the full specifications of the Dreamcast, with Nishigaki saying they used half the console's polygon display capacity. The music was composed by Toshihiko Sahashi, whom Nishigaki wanted to create a Hollywood-style score for the game. The opening and ending themes were recorded using a 60-piece orchestra conducted by Kouji Haishima. Nishigaki wanted the score to emulate the music of John Williams. Blue Stinger was Sahashi's first video game job, treating it like a background movie score. In contrast to his earlier movie and television work, Sahashi had as much time as he wanted to create the score. The opening and ending themes were composed to match the finished movie scenes. Only the opening and ending themes used CD-quality music, with the rest of the game music using the Dreamcast's sound chip. Voice acting for all regions was in English, with the Japanese release using subtitles to emulate Hollywood movies. The two leads were voiced by Ryan Drummond and Deem Bristow. The voice recording was directed by Lani Minella, who also voiced Janine. All three at the time were voicing characters from the Sonic the Hedgehog series. Nishigaki felt Drummond had done a good job voicing Eliot. Release Blue Stinger was announced at the Tokyo Game Show in September 1998 as part of Sega's launch lineup for the Dreamcast. It was ultimately delayed into the following year to further polish the title. Nishigaki described Sega as
