Fantasy Zone
is a vertical-scrolling shoot 'em up game originally released by Konami as an arcade game in 1985 in Japan. Along with Sega's "Fantasy Zone", released a year later, "TwinBee" is credited as an early archetype of the "cute 'em up" type in its genre. It was the first game to run on Konami's Bubble System hardware. "TwinBee" was ported to the Family Computer and MSX in 1986 and has been included in numerous compilations released in later years. The original arcade game was released outside Japan for the first time in the Nintendo DS compilation "". A mobile phone version was released for i-mode Japan phones in 2003 with edited graphics.
