Despite being initially announced as a PlayStation 3 exclusive, Metal Gear Solid 4: Guns of the Patriots is now also going to be released on Xbox 360.
There are also unconfirmed rumours that there may be a Wii version, albeit a cut down one.
Some source claim that the 360 version will come with exclusive content that won’t be found on the PS3 edition.
A Konami spokesman said, "The game is set after the events of MGS2 and players will reprise the role of top secret agent Solid Snake with appearances by characters throughout the MGS series. With the addition of online capability, MGS4 is a leading product and will signal the dawn of a new gaming era for the MGS series".
