Metal Gear Solid 4: 25th Anniversary Edition spotted

Konami is preparing a "25th Anniversary Edition" of its 2008 action game Metal Gear Solid 4: Guns of the Patriots. That's according to United Kingdom-based retailers Zavvi and ShopTo (via Eurogamer), which have posted product listings for a new PlayStation 3 game due November 30.

Konami has not announced any such product, and the publisher was not immediately available for comment.

Metal Gear Solid 4: Guns of the Patriots launched in June 2008. It did not receive any downloadable content, but a patch this summer brought Trophy support to the game. Additionally, its multiplayer component--Metal Gear Solid Online--was taken offline in June.

As part of its 25th anniversary celebration for the Metal Gear Solid franchise, Konami this summer announced Metal Gear Solid: Ground Zeroes as well as a full-length feature film based on the series.
