Metal Gear Solid: Digital Graphic Novel isn't a game in the usual sense. The only thing even remotely game like about it is the Memory Building mode which enables players to pause the graphic novel and go searching through the images to find hidden pieces of Snake's Memory which can then be linked up to build a complete Database on MGS1. The graphic novel itself features the artwork and story from the complete first series of MGS comics, animated and set to background music. Digital Graphic Novel features no voice acting.

This promotional version was only released to stores and magazines for reviewing. The myth about Promo versions is that they're only samples of the game. This is not the case. The promo versions are actually the full game in their own unique packaging.
