Metal Gear Solid 4: Guns of the Patriots is the final installment in the Metal Gear Solid series and is projected for a North American release in 2007.

MGS4 will harness the full potential of the PlayStation 3 and the revolutionary 'Cell Processor' technology developed by Sony.

Six years after the Manhattan Incident, the world has changed. War is now a well oiled business, a series of endless proxy conflicts between Private Military Companies (PMCs). This will be Snake's final mission.
