As far as the story goes, it's a straight-up recreation of 1998's Metal Gear Solid. Some of the dialogue is verbatim from the game, while a few of the filler lines sound like a junior high short story ("First floor basement, here I come"). Watching it all the way through once is cool enough, but you're going to spend hours examining each panel, hoping to find some elusive memory that's keeping your mind-matrix-thingy from being complete.
Even though this is a largely visual experience, the sound effects and accompanying music are top of the line. We've read our fair share of comic books, but even our imaginations were impressed by the auditory orgy of awesomeness spewing from the PSP's tiny speakers. You may be reading most of the time, but it's never dull at all.
