Im sure it is interactive somehow...
From a review...
Unlike the previous two installments, the Digital Graphic Novel really isn't a game; it's more like a visual interactive experience that depicts the incidents of Shadow Moses in a graphic novel format. The entire disc is broken down into three modes: the VR Simulation mode, the Mental Search mode and the Memory Building Simulation mode. The VR Simulation mode is the primary thrust of the title, and starts up almost immediately once the disc has been loaded. Running about two hours long, The VR Simulation mode is comprised solely from images by Ashley Wood, an Australian artist who is rather familiar with the Metal Gear Solid universe (he's drawn the official comic book for years).
Wooooooo Aussie guy did the animations!
