Blast Wind (ブラストウインド) is a Sega Saturn vertical shoot-'em-up game developed and published by Technosoft. A port of the developer's titular unreleased 1993 arcade game Blast Wind[3][4], it was released exclusively in Japan in January 1997.
A nuclear shockwave has all but destroyed the entire population of Earth. The remaining humans on the planet were gathered aboard a ship called the Ark by a prophetic man named Noa. After the radiation dissipated, humankind emerged from the Ark and began building anew.
However, the developing civilization came under attack by a society named Gorn (a reference to the ORN Empire from Technosoft's popular shoot-'em-up series Thunder Force), the embodiment of machines and artificiality. During the nuclear winter, Gorn was sealed beneath the Earth's crust but surfaced when the remaining humans returned. Humanity must fight back against Gorn, using ancient weapons unearthed by the new civilization and two "Ultimate Destroyers" known as Kyō and Forn.

History
Originally developed as a 1993 arcade game, Blast Wind failed its location test and missed its advertised release date.[3][4] Later the next year, a retooled version of the game titled Inazuma Saber also received a location test, this time with a humorous tone and comedic banter between player characters and bosses. This version also failed its location test, and went equally unreleased.[3][4] Nearly four years later, Technosoft revisited the original 1993 version of the game for a Sega Saturn port.
Produced in very limited quantities, Blast Wind has become one of the rarest non-promotional Sega Saturn releases.
