Metal Gear series

Metal Gear (メタルギア) is a critically acclaimed series of stealth games created by Hideo Kojima. The games are developed by Kojima Productions and published by Konami. In the series, the player takes control of a Special Forces Operative repeatedly facing off against the latest incarnation of the eponymous superweapon "Metal Gear"; a bipedal mecha walking tank with nuclear launching capabilities. The series is famous for pioneering the stealth game, for its lengthy cinematic cutscenes, intricate storylines and its exploration of the nature of politics, warfare, environmentalism, censorship, genetic engineering, artificial intelligence, loyalty, reality, subjective vs. universal truths and other philosophical themes. The series has accumulated great success, selling over 26.5 million copies. Kojima indicated that the series was split into two trilogies: the Solid Snake trilogy, and the Big Boss trilogy. However, since that statement, both trilogies have expanded into pentalogies.

Overview
Each game involves protagonist Solid Snake (or someone else called Snake) sneaking around maps and avoiding soldiers. He is armed with various weapons, most of which exist in the real world. At certain points in the game, he has to fight various bosses who usually have different superhuman or supernatural abilities. In most games, the penultimate boss is the latest incarnation of the weapon Metal Gear, with following bosses being one-on-one confrontations with that game's main antagonist.

Kojima originally planned to release the third Metal Gear game, to be called Metal Gear 3, for the 3DO Interactive Multiplayer in 1994. However, due to the declining support of the 3DO hardware, development of the game shifted to the PlayStation shortly after the 3DO version of Policenauts was released. Kojima retitled the game Metal Gear Solid, choosing this over the working title Metal Gear 3. This was due to the fact that he believed that the first two MSX2 games in the series were not well known at the time. He used the word "Solid" because thanks to 3D computer graphics, he could now create a "solid" game world, although he also partially attributed the title's inspiration to Solid Snake. Sequels to this game generally use the Metal Gear Solid title and generally follow a new numeral progression. The MSX2 games have sometimes been omitted from timelines representing the series' internal chronology, instead focusing on the more widely known console releases beginning with Metal Gear Solid. However, the first two MSX2 games are still a part of the Metal Gear canon.

Main series
The main series, considered part of Metal Gear canon, consists of the following games (in release order):

Metal Gear

However, Gray Fox disappears with his last message simply reading "Metal Gear..." so rookie FOXHOUND recruit Solid Snake infiltrates Outer Heaven and put a stop to the world's most powerful weapon.

Metal Gear 2: Solid Snake
In 1999, the creator of a new species of algae which could produce petroleum-grade hydrocarbons with little expense and effort has been kidnapped by the renegade nation Zanzibar Land, the only country left with nuclear strike capability thanks to Metal Gear D.

In the year 2007, Philanthropy found information leaked about the Marines' new Metal Gear RAY to combat the over abundance of Metal Gears. In response, Otacon assigned Solid Snake to take photographic evidence but the tanker is blown up and sunk by Revolver Ocelot.

In the year 1964, FOX operative Naked Snake is sent into Tselinoyarsk in a mission to rescue a defecting Russian scientist while working on the Shagohod, a terrifying weapon that's capable of launching a nuke from anywhere, but his mentor The Boss interferes and defects to the Soviet Union.

To prevent the new FOX commander from activating a powerful new nuclear weapon, Big Boss and Roy Campbell set out to convince the Red Army soldiers to join them and rise up against FOX.

Metal Gear Solid 4: Guns of the Patriots
In the year 2014, the restriction of military intervention on foreign soil has been eased which fuels the need for private military companies (PMCs) to fight proxy wars for business purposes. nanotechnology has become prominent, both to enhance the capabilities and enforce the loyalty of mercenaries. The nanomachine system "Sons of the Patriots" is used commonly by the PMCs. The five largest PMCs are owned by the Outer Heaven mother company with Liquid Ocelot as the CEO. Amassing an army rivaling that of the U.S. Army, Liquid Ocelot prepares to launch an armed insurrection by taking control of the system. With the world once again in crisis, Roy Campbell deploys Old Snake to terminate Liquid Ocelot once and for all.

Metal Gear Solid: Peace Walker
In 1974, Latin America becomes a key to maintaining the power balance between the East and the West yet Costa Rica has miraculously managed to maintain peace and neutrality. But in the country's various regions, a mysterious armed force seems to be engaging in specific activities. While stationed in Colombia, South America, the mercenary company Militaires Sans Frontières (French for "Soldiers Without Borders"), led by Big Boss (Naked Snake) and Kazuhira Miller, are approached by visitors (Ramón Gálvez Mena and Paz Ortega Andrade) from Costa Rica. To preserve peace in this "nation without a military", the MSF moves into action and will come to be known as the founders of "Outer Heaven."

Metal Gear Rising: Revengeance
Four years after the events of Liquid Ocelot's Insurrection, Raiden has been contracted for VIP protection, military training, and other duties in a developing country piecing itself back together after a bloody civil war. Raiden largely did this to support his family without having to return to direct combat situations. He is protecting a VIP, when they are attacked by a cyborg organization led by Sundowner and Samuel Rodrigues, which eventually leaves Raiden completely defeated. Raiden is reconstructed by his PMC Maverick Security Consulting, Inc., and his search for Sam and the company he's working for, Desperado Enforcement LLC., drives him into a quest for vengeance.



Metal Gear Solid V: Ground Zeroes/The Phantom Pain
