A separate add-on to Metal Gear Solid: Portable Ops that focuses mainly on the game’s multiplayer component. There is a single-player mode called Infinity Mission, although no plot is associated. In addition, new tasks and tutorials are available for players just starting. This game continues the theme of capturing and enlisting new allies by supporting up to six players over WiFi and introducing new characters such as Old Snake from Metal Gear Solid 4, Roy Campbell, and Raiden from Metal Gear Solid 2.
