During a training mission in late February 2005 on Shadow Moses, a remote island off the coast of Alaska containing a nuclear weapons facility, FOXHOUND and the Next-Generation Special Forces rebelled against the United States Government, under the command of Liquid Snake. Their target was the advanced weapon system Metal Gear REX, a gigantic robotic weapons platform with worldwide nuclear strike capabilities. Their demand was the body of the greatest soldier who ever lived, Big Boss, which, through gene therapy, they could use to create an army of ultimate soldiers.
