Detana!! TwinBee Yahhō! Deluxe Pack is a Saturn/PlayStation compilation of two games from Konami's TwinBee series. The series is considered to be part of the sub-genre of "cute 'em up": games that feature comical and brightly-colored graphics in lieu of the usual military/sci-fi aesthetic featured in shoot 'em ups.
Detana!! TwinBee and TwinBee Yahhō!, the two games featured here, were both released in the Arcades before seeing home conversions. Detana!! TwinBee was originally released in 1991, while TwinBee Yahhō! was released in 1995, shortly before this compilation was released later the same year.
