In the year 19XX (later established to be 1995 in Metal Gear Solid), 200km north of Galzburg, South Africa, lies Outer Heaven, a fortified state founded by a "legendary mercenary". Word had gotten out to the western world that deep within the Outer Heaven stronghold, a weapon of mass destruction is being constructed. The United States government orders the high-tech Special Forces unit FOXHOUND to infiltrate the fortress, assess the situation and neutralize the threat. In his mission, FOXHOUND operative Gray Fox infiltrated the Outer Heaven stronghold. Days later, contact with Gray Fox is lost and his last transmission simply reads "METAL GEAR..."

Operative Solid Snake, FOXHOUND's newest recruit, is ordered by squad leader Big Boss to rescue Gray Fox and carry out his mission, "Operation: Intrude N313". Upon insertion into Outer Heaven, Snake makes contact with local resistance members Kyle Schneider, Diane, and Jennifer. Using all of his skills and the equipment he procured on site, he manages to rescue Fox. He learns from Fox that Metal Gear is the codename of a nuclear warhead-equipped bipedal walking tank, which can engage and dominate in all forms of combat as well as launch its nuclear warheads from any location. Outer Heaven plans to use Metal Gear to impose itself as the new world superpower.

In order to destroy Metal Gear, and topple the Outer Heaven mercenaries, Snake rescues the lead engineer of Metal Gear, Dr. Drago Pettrovich Madnar, and his daughter, Ellen. Armed with information on how to destroy Metal Gear, his skill and indomitable spirit, Snake fights through the entire Outer Heaven force. He begins to notice that traps being set for him are too precise, and wonders how information on his activities is being tracked. Moreover, Schneider is ambushed by hostiles and is presumed dead after losing contact with Snake. The final hostage Snake rescues tells him that the mysterious "mercenary leader" of the entire base is none other than Snake's C.O., Big Boss, and that Outer Heaven is under his command.

Upon breaching the core of the base, Snake is able to neutralize Metal Gear before it reaches completion. As he makes his way out of the compound's basement, he is confronted by Big Boss himself; the corrupt leader had been using his connections within the U.S. government to steal military intelligence, establish his own mercenary force, and fund his activities. It was his aim to have Outer Heaven become the world's most powerful nation, able to bring even the western nations to their knees. He had the rookie Snake sent in, hoping to have him captured and feed the U.S. government misinformation, but had quite obviously underestimated Snake's capabilities.

Having lost Metal Gear and much of his force, Big Boss starts the self-destruct sequence for the compound, and promises he will not die alone; Snake will join him. An underground battle ensues, and despite injury, Snake defeats Big Boss and escapes the Outer Heaven compound as it crumbles in flames behind him. After the ending credits, a message from Big Boss is displayed saying that he will meet Solid Snake again.

Gameplay: 

The player must navigate the main character (codenamed "Solid Snake") through various locations, while avoiding visual contact and direct confrontation with patrolling guards. If the player is seen, the game enters the "Alert Mode." In this situation, the player must hide the character in order to leave the mode. The method of escaping varies depending on the circumstances behind discovery:

If a player is seen and only a single exclamation mark (!) appears over an enemy's head, only the enemies in the player's present screen will attack and an escape can be made by moving to the adjacent screen. 

However, if two exclamation marks (!!) appear over the enemy (or the player triggers an alarm by being spotted by a camera, infrared sensor or by using an unsilenced weapon), reinforcements from off-screen will appear as well. The player can only escape by eliminating all incoming enemies or by simply moving to a different floor. 

The player starts the game unarmed, but eventually gains access to a variety of firearms (starting with the Beretta M92F) and explosives and working his way up to machine guns and guided rocket launchers. Ammo and supplies for each weapon are limited, but are easily replenished. Weapons can not only be used to kill enemies, but also to clear obstacles (such as hollow walls or electrified floors). Snake can also use his fists to punch and defeat patrolling enemies. Occasionally if the player defeats a guard with punches without alerting anyone, the defeated guard will yield a single unit of rations or an ammo box that can be picked up.

The enemy base consists of three different buildings, with multiple floors (including basement levels) within them. The player uses key cards and other items to unlock doors or explore new areas. Doors will only open to their corresponding key cards. Bosses also appear throughout the game to interfere with the player's progress.

Information can be obtained by rescuing hostages being held captive within the buildings. After rescuing five hostages, the player is given a promotion, increasing their "Rank" (up to 4 stars max), allowing for bigger ammo capacity and maximum health. However, if a hostage is killed, the player is demoted to the previous rank.

A transceiver is available for the player to communicate with their commanding officer (Big Boss) or one of the resistance members operating covertly within the fortress. Each of Snake's allies has an extensive knowledge on specific subjects. The transceiver system is completely room-oriented, as certain radio transmissions occur only in certain locations.
