Snake's Final Mission:
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.
Set in 2014, five years after the "Big Shell Incident" (the events of the Plant chapter from Metal Gear Solid 2), Metal Gear Solid 4 portrays a world where the restriction of military intervention on foreign soil has been eased, fueling the need for private military companies (PMCs) to fight proxy wars for business purposes. Nanotechnology has become prominent, both to enhance the capabilities and enforce the loyalty of mercenaries. The nanos that are in the PMCs are called "Sons of the Patriots" or "SOP". The five largest of these PMCs (Which are named Praying Mantis, Otselotovaya Khvatka, Werewolf, Pieuvre Armement and Raven Sword) are owned by a single mother company named Outer Haven, which is operated by Liquid Ocelot. Amassing an army whose manpower rivals that of the United States, Liquid prepares to launch an armed insurrection by taking control of SOP. Liquid will have the power to control all of the PMCs. With the world once again in crisis, a rapidly aging and disillusioned Solid Snake is deployed into the Middle East by Roy Campbell to terminate Liquid. Guns of the Patriots will take place in five locations, Middle East, South America and Eastern Europe.
Several elements from previous titles return in modified forms. Players will also use a new form of camouflage called "Octocamo", which replaces the camouflage system featured in Metal Gear Solid 3. Dark blue when disabled, the Octocamo suit allows the wearer to blend in with any surface within a few seconds. Snake will also be partnered with a robotic drone, the Metal Gear Mk. II, which allows him to communicate with other characters, in addition to the CODEC radio system from previous games. It is also capable of engaging enemies using an electric shock, as well as providing reconnaissance.
