The American version of Subsistence is slated to included everything the Japanese version does. For those who haven't been paying attention, that includes:

Disc 1: Subsistence: Play MGS3
  • The original game
  • Two new difficulty levels (Super Duper Easy and European Extreme)
  • New face paint and camouflage
  • The ability to switch between the traditional bird's-eye camera and a new rotatable Third Person View Camera
  • Demo Theater, where you can watch all the game's cut scenes with your choice of paint and camo, as well as the option of "Peep Mode"
  • PSP connectivity: if you hook a PSP with Metal Gear Acid 2 up to a PS2 with Subsistence via a USB cable, you can transfer the photos you've taken with MGS3's in-game camera to your PSP, where you can view them as 3D images using the Solid Eye peripheral that comes with MGA2
Disc 2: Persistence: Extend MGS3
  • Metal Gear Online (MGO)
  • An array of objectives including Sneaking Mission, Team Death Match, Death Match, Capture Mission, and Rescue Mission
  • Leader characters with unique techniques, including guest characters from other franchises, such as Reiko from Rumble Roses
  • Duel Mode, where you can play all of MGS3's boss battles
  • An updated version of Snake vs. Monkey with new stages
  • Secret Theater Mode, where you can view the hilarious series of original movies using MGS3's engine that were previously only available on the official MGS3 website
  • Metal Gear and Metal Gear 2: Solid Snake, the games that started the franchise, fully translated and made available outside of Japan for the first time
Disc 3: Existence: Watch MGS3
  • All the cut scenes in MGS3 edited together with additional footage and remastered sound to form a seamless three-hour feature (with chapter stops, of course)
