Metal Gear Solid 4 Guns of the Patriots

In 2014, the world is in chaos, the "war economy" plunging the world into never-ending battle. This fuels the need for private military companies, the five largest of which (together rivaling the power of the entire United States Army) are owned by a single mother company, Outer Heaven, with Liquid Ocelot at the helm. Liquid Ocelot, a fusion of the consciousness of Liquid Snake and the body of Revolver Ocelot, is once again set on world domination. Solid Snake, now also referred to a Old Snake due to his advanced accelerated ageing, is dispatched to assassinate Liquid Ocelot as a personal favor to Roy Campbell.
