It seems odd to think of the PlayStation Portable as an eBook reader, but less odd as a graphic novel reader and a perfect natural as a Metal Gear Solid graphic novel reader, seeing as the original PlayStation game it's based on is as much cherished for its artistic flair and deep/cheesy story-telling as it is addictive tactical-espionage-action gameplay. So there you go.

Metal Gear Solid Digital Graphic Novel is viewable/playable in a couple of different modes, but it all delivers a cool mix of rough-sketch frames, highly detailed renders and a few animated sequences. It all amounts to more than just reading a Metal Gear Solid comic book on your PSP; there's a higher level of interactivity, obviously--comic books don't have menus, for starters--plus it's augmented with a bang-on soundtrack and sound effect ambience making the "reading" experience that much more immersive.

For the hardcore fans/dweebs, the novel can also be played as a fact-finding game of sorts with interactive memory elements in select spots that, once flagged, can be strung together into a modestly coherent segment of its own, like a flashback, to bring you up to speed on some obscure plot point. Good thing, too, seeing as there's no such thing as an obvious plot point in the MGS universe. Case in point, even the flashback segments have memory units hidden within to create still more revealing flashback segments. Of course, all that searching and scouring and stringing is just brain pain for the average fan.

Fortunately, at its most basic, the MGS Digital Graphic Novel is still a tantalizing, two-hour read for all; a nice new, low-stress, comparatively low-cost way to kill time on the bus, without actually killing anything.
