As with its predecessors, Metal Gear Solid 4: Guns of the Patriots is a story-driven game, with seasoned hero Solid Snake drafted for one final mission. Set across stages including the Middle East and South America, the now aged Snake has been asked to assassinate his old adversary, Liquid Ocelot. To do this, however, he must make his way through a series of battlefields, using his legendary stealth abilities and all-new OctoCamo suit to avoid detection and to reach his target. With series favourites such as Meryl Silverburgh, Raiden, Hal 'Otacon' Emmerich, and Roy Campbell returning, and with all new gameplay features including a remote-controlled 'Metal Gear Mk. II' droid and enhanced CQC (Close Quarters Combat) system, MGS4 will round of the Metal Gear saga with a fittingly cinematic and gripping final outing.

Metal Gear Solid 4: Guns of the Patriots is the final chapter in the saga of Solid Snake which sends him around the world in pursuit of his arch nemesis, Liquid Ocelot. Armed with new gadgets and abilities, Solid Snake must shift the tides of war into his favor, using the chaos of the battlefield to infiltrate deep into enemy territory. In his globetrotting final mission, Snake must sneak deep into enemy locations in the Middle East, South America, and other corners of the Earth to foil Liquid Ocelot's plans for total world domination.

The Trophy system was introduced to PS3 in the middle of 2008. However, by that time, MGS4 had already finished development and was about to launch, so Kojima Productions were regrettably unable to implement Trophies at launch but has it on the developers to-do list ever since.

Trophies will finally be coming to MGS4 in the beginning of August!
