Silpheed (シルフィード) is a vertical scrolling shoot-'em-up released for the Sega Mega-CD in 1993. It is a remake of an older shooter with the same name released for several home computers of the late 1980s, sporting more colours, different levels, enhanced music and updated graphics.
It is notable for its use of 3D graphics - though the gameplay is strictly two-dimensional, the scenery is rendered using polygons in a similar manner to Star Fox or Virtua Racing. Silpheed is slightly less impressive than those two games however, as most of the action takes place in space, which typically lacks scenery.
Streaming technology is used heavily in this game. Read errors can occur on systems that run other games flawlessly
