Regardless of whether you wind up playing through the Infinity Mission mode or capturing players via AP Scanning, the real meat of the game lies in the multiplayer missions, which have received a number of adjustments. For one thing, players will have the option to play as Raiden from MGS 2 and Old Snake from the forthcoming MGS 4. A number of new maps have been included in this title, such as going through a hanger with Metal Gear Rex in the background, which shows off some impressive scale on the PSP's screen. There will also be some new gameplay modes as well, and an augmented cyber-survival feature for players looking to recruit soldiers from Konami's servers. Don't worry if you're somewhat familiar with the old maps and versions of the online Portable Ops experience, as those have been included as well.
