Disc 2, called Persistence, included, primarily, Metal Gear Online (MGO) featuring sneaking missions, team deathmatch, deathmatch, capture missions and rescue missions. The official servers for the original Metal Gear Online were shutdown in 2007. Also included is a Duel Mode, where the player can take on all the bosses and major enemy encounters (such as the Ocelot Unit, and bike pursuers) as they are in-game, or with a special stipulation such as limited ammo. Beating this mode with all first place finishes will unlock the DPM and the Green facepaint in the main game. Also, the Ape Escape minigame Snake vs. Monkey was moved here from Disc 1, with two new levels Return of the Living Apes (using the Groznyj Grad main Weapons Lab hangar) and The Apes of Wrath (using Rokovoj Bereg). Also included is a Secret Theater mode (the videos for which were shown on the official Konami website), and playable versions of the original Metal Gear and, for the first time outside of Japan, Metal Gear 2: Solid Snake.
