It was the beginning of a new era - the Cold War.

October 16, 1962. The President of the United States received word that the Soviet Union had deployed nuclear missiles in Cuba. The world trembled in fear as the prospect of nuclear war loomed ever closer. After days of tense negotiations, the Soviets finally agreed on the 28th to withdraw their missiles from Cuban soil. With the resolution of this incident, later to be known as the Cuban Missile Crisis, it seemed that humanity had survived yet another threat to its existence.

However, there was a secret condition in the deal that put an end to the crisis. Nikolai Stepanovich Sokolov, a Soviet scientist who had defected to the West, was to be sent back to the Soviet Union. The U.S. government agreed to this stipulation, and returned Sokolov to his native land. Little did they know that Sokolov was to be the designer of a nightmarish weapon. Now, with Sokolov back in their hands, the Soviets are ready to resume its development. If this weapon is completed, it will mark the beginning of a new age of fear.
August 1964. Realizing at last the urgency of the situation, the CIA forms a plan to recapture Sokolov. They dispatch the covert FOX unit to Sokolov research facility, located to the south of the great Soviet fortress of Groznyj Grad. Led by former SAS member Major Zero, FOX is a next-generation special-forces unit that operates both as a specialized combat group and as a covert intelligence outfit. The FOX unit's modus operandi is to send a single agent, backed by radio support from afar, into enemy territory to carry out solo sneaking missions.

August 24. A lone soldier swoops down from out of the blue. The man's code name is Naked Snake.

Life's biggest mission to "live through".

Mother natures surrounds you from all directions in the "jungle". The most important thing while placing yourself under the tough conditions of an infiltration mission is obtaining food to survive. If the "stamina gauge" -- symbol of all life activities -- goes low, your healing power goes down, you cannot aim your gun properly, and your overall mission becomes harder to accomplish.

The jungle setting abounds with mother nature's gifts -- snakes, birds, fish, fruit, etc. Find your prey in the grass, branches, and in water and use your gun, knife, and traps to capture them for food.
You must also keep in mind changes in the climate such as rain and temperature to maintain your stamina.

"Close Quarters Combat" -- a fighting technique against nearby enemies.

In the jungle where your view is obscured, enemies can jump right in front of you suddenly without your noticing them till the very moment. You might not be able to use your artillery because of rocks and trees that come in your way. CQC (Close Quarters Combat) is a fighting technique effective against enemies that are right near you. While holding both a handgun and combat knife, you grab the approaching enemy and throw them. Simple controls allow you to use the enemy as a shield or threaten them for valuable information.

By combining CQC with middle and long-range battle (with weapons obtained through the mission), you can create your own fighting style in those battles that are not always avoidable.

Blend into nature with "disguise" and fool the enemy eye.

Wear camouflage gear that matches your environment and apply face paint to fool the enemy eye. Becoming one with your surroundings is the most effective way to hide yourself from the enemy.
By using disguise that matches the jungle, swamp area, indoor environments, daytime and nighttime, you can improve your chance of surviving drastically. Simply hiding behind something in extreme circumstances in enemy territory might not be enough. Constantly being aware of your environment, or "knowing nature", is the shortcut to completing your mission successfully. Into what colors will the warriors change during their endeavors to survive the Cold War?
