Hideo Kojima has shown off Metal Gear Solid: Portable Ops Plus with the trailer below. The Portable Ops expansion will feature new characters, missions and gameplay modes, as well as tutorials for beginners and a new single player mode.

Portable Ops Plus has been given a Japanese release date of September 20th. The expansion alone will cost Y2,400 (£9.50), while a package that includes the original will sell for Y4,300 (£17). No details are available on a British release date or pricing yet, although SPOnG would not be surprised to see an announcement at Liepzig next month.

Now feast your eyes on the trailer below, and if that doesn't sate your appetite for Metal Gear footage, have a look at the E3 trailer for MGS4.
