Yes. Subsistence includes 2 discs. There are 3 if you plan on buying the Limited edition, but the third is just a compilation of all the game movies (+ a couple of gameplay ones) made into 3 hour long movie. The differences are: 1. New camera mode. You've probably already heard about it. 2. Downloadable camoflauges. They're quite nice, but mostly a waste of time. 3. New Snake VS. Monkey levels. 4. "Dual Mode", simply a boss time challenge. 5. "Secret Theater" - spoof videos. Some of them are quite funny. 6. If you are talking about the NTSC version of Snake Eater, there's also the "European Extreme" difficulty.
