I'm interested in picking up Metal Gear Solid: Portable Ops but don't know if I should pick up the original or Plus. All of the information I can find is rather confusing. Does Portable Ops Plus still have the single player from Portable Ops? That's what I'm interested in but I'm confused as to what's where.

No.

Simple enough. Thanks. I'll look for just Portable Ops then.

Yes Portable Ops has the single player experience that Portable Ops Plus doesn't have, but offers a single player experience of it's own that is not included in Portable Ops. Straight forward enough?

So, there is an entirely different story element to Portable Ops Plus? I was going to pick up Portable Ops since it's the only canon Metal Gear Solid portable game. Does Portable Ops Plus also fall under that umbrella and what is the story about?
