The original
Silpheed game was created for the
PC-8801, and released on December 5, 1986. Another version for the
FM-7 was released on March 3, 1988. In the same year, the game was brought to the United States for the first time by
Sierra On-Line who ported the game to DOS and other platforms. The DOS version (1.0) released in April 1989. Later in the same year, the version 2.3 has added
Game Blaster soundcard support and bundled with Game Blaster soundcards. In 1989, Sierra On-Line also ported
Silpheeed to the
Apple IIGS, which supported the same 640x200 graphics modes of the original NEC PC-8801 version, and its full musical score (based on the
Roland MT-32 soundtrack from the DOS version) using its 15-voice
Ensoniq sound chip. The storyline is set in the future (no date is specified, but 3032 is referred to as the date when an alien ship was discovered that led to rapid technological advancement and allowed humans to colonize outer space) a terrorist named Xacalite has stolen "planetary buster" missiles and a battleship named Gloire. The fleet is not close enough to Earth to get there before Xacalite destroys it, so the supercomputer Yggdrassil orders the experimental SA-08 Silpheed fighter, a prototype, to be used to destroy Gloire.
Sega CD The Sega CD port of
Silpheed places
polygon ships over a
pre-rendered video background; this method is also seen in other video game titles, like Namco's
Galaxian 3 in 1990 and
StarBlade in 1991,
Sony Imagesoft's ''
Bram Stoker's Dracula'' in 1992, and Micronet's
A/X-101 in 1994 for the Sega CD. The game's story concerns a space war campaign when terrorists—led by a man named Xacalite—hack into the mother computer of Earth, granting them control over all the space weaponry of the
Solar System. The Earth's only hope is a small fleet outside the computer's reach, provided with a squadron of SA-77 Silpheed dogfighters (referred to as "prototypes" in the manual for the PC version). In the ending credits sequence of this version, there are cinematic animations of scenes depicting the fighters flying through stages in the game. ==Reception==
