田尻智
"Twin Hawk" was created as a commission for Taito by most of the same team that worked on previous projects at Toaplan and made use of the former's Taito X System board. Yuichirō Nozawa, who previously had not worked on shoot 'em up titles, served as its game designer. Both Sanae Nitō and Yuko Tataka also acted as designers in the development cycle. Osamu "Lee" Ōta scored the soundtrack, becoming his sole work as composer for a shoot 'em up title. The game was released by Taito in Japanese and European arcades on June 1989. On 29 August, 2018, an album containing its audio, as well as from other Toaplan titles was published exclusively in Japan by City Connection under their Clarice Disk label. It was also featured on a Japanese TV show, with "Pokémon" creator Satoshi Tajiri reviewing the arcade version.
