MGS Portable Ops+ has been announced for the PSP. Released in Japan sometime during September, the game will feature new playable characters, multiplayer stages and single player mode called Infinity Missions. But the news is pretty ho hum until you realize that this title is an expansion being released on the PSP.
Portable Ops+ apparently needs the original game, to some extent, in order to run on the PSP. That's why it will be sold in two SKUs—one version with just Ops+ and the other with the original Ops bundled with Ops+. We're guessing the expansion is really just a UMD containing an enhanced version of Portable Ops, only unlockable if a save file from the original Ops is found on your memory card. Because until the fabled (now extinct) PSP2 with built-in storage is released, the idea of a true "expansion" seems a bit contrived. You know, like those Xbox Live "downloads."Kojima [via eurogamer]
