Though it was never officially announced, we always suspected Metal Gear Solid: Portable Ops + would be coming to America. Now comes word that the expansion to last year's PSP action hit has gone gold and will hit North American stores on Nov. 13.

MPO+ will feature new characters, multiplayer modes and stages, weapons, and character skills. Also in the $20 package is a new single-player mode called "Infinity Mission." This new mode will add new goals and objectives to the original single-player stages.
