We're still not quite sure what to make of Konami's upcoming Metal Gear Solid Digital Comic thing for PSP, given that it's really not a game as such - more an interactive MGS bible, as the publisher's bigwigs would have it.
Either way, we've got a new 'gameplay' trailer of the not-really-a-game, which tasks you with roving through a multimedia-ized version of the existing MGS comic book, rifling for clues and scanning various objects to unlock all sorts of stuff about Snake and crew.
Feel free to have a gander in preparation for the title's still to be announced release date.
