The Fury is a former SovietCosmonaut. After World War II, once the Cobra unit was dismantled, he returned to Russia. He was sent into outer space on a Cosmonaut flight. An accident occurred, and upon re-entering the Earth's atmosphere, he suffered severe burns all over his body, which left him unable to feel any pain. While he was being burned, he saw the Earth obscured by the wall of fire. That caused him to be obssessed with a vision of the Earth in flames, as well as develop pyromaniacal tendencies.
As with the rest of the Cobra unit, his codename reflects the specific emotion he portrays while on the battlefield. He feels unrelenting fury towards the world and everything else while he is fighting.
MetalGearSolid3 is set during the Cold War in 1964, where Naked Snake is sent to the jungles of the Soviet Union.
Kojima views MetalGearSolid, Sons of Liberty and Snake Eater as a trilogy, and wished to keep the camera the same as the previous two in order to keep the feel of the three games the same.
MetalGearSolid3: Snake Eater was well received by the media, and was given high scores by some of the most prominent gaming critics.
