The Entire Metal Gear Timeline Explained

The gaming community has its eyes glued to Death Stranding, the newest mystery spearheaded by producer Hideo Kojima, and it's easy to understand why. While he's worked on various titles throughout his career, he reached new heights of fame with his work on the Metal Gear Solid series. Spanning across nearly three decades, the games tell the epic saga of Big Boss and his clone-sons, particularly the iconic Solid Snake.

If you've never played the Metal Gear games, the story might be the most daunting part of the series. Each game finds itself on a different place in the timeline. For example, MGS3 tells the beginning of the entire story, but the next game, MGS4, tells the end of the Snakes' saga. Then MGS5 bridges the story between a spin-off prequel and the very first Metal Gear game. But the confusing release timeline doesn't even compare to how wildly baffling some of the plot twists are.

So we've compiled a quick timeline of the Metal Gear series to help you navigate through Kojima's wild ride.

Throughout the new mission, dubbed Operation Snake Eater, Snake coordinates with Major Zero, who provides situational intel. Additionally, Snake often runs into a KGB operative named Ocelot. The Russian has a thing for Westerns, only bolstered by Snake telling him to use revolvers because they jam less. More often than not, though, Ocelot becomes a punching bag for both Snake and Volgin.

Snake sets out to slay Volgin and destroy the Shagohod, as they're both in the way of his true mission: killing The Boss. Then, in a student-becomes-the-master confrontation, Snake engages his mentor in hand-to-hand combat, after which a lot of exposition gets dumped on the player. On her top-secret CIA mission, The Boss was meant to defect to Russia in order to secure the Legacy. However, the nuclear attack courtesy of the Davy Crockett missiles escalated tensions between America and Russia. This led to Snake's current mission, which makes him clean up The Boss's mess.

To maintain the cover story, he must kill her, even if begrudgingly so. He returns home a hero, and he's awarded the title Big Boss. He mourns the loss of his mentor, who was forced to die because of the CIA's crusade for the Legacy. It's revealed later that Ocelot actually works for the CIA, and he obtained half of the Legacy before Volgin passed.

In Metal Gear Solid: Peace Walker, Big Boss establishes the base of operations for the MSF with the help of his second-in-command, Kazuhira Miller. Big Boss calls this location, off the coast of Costa Rica, Mother Base. A rogue CIA group has taken over the nearby nation and installed a nuclear deterrent, the eponymous Peace Walker.

Big Boss and the MSF eventually destroy Peace Walker, with the help of a child soldier named Chico. The MSF starts building its own nuclear deterrent called Metal Gear ZEKE, thanks to the help of some scientists. But in a turn of events, a Patriots agent named Paz takes over ZEKE, threatening to use it on America and blame it on the MSF. However, she'll stop if Big Boss joins the Patriots again.

Refusing to return to Zero, Big Boss destroys ZEKE. In the explosion, Paz presumably dies, but it is later revealed that she miraculously survives. Unfortunately, she gets kidnapped by the XOF, another rogue CIA organization. The XOF used to do the Patriots' dirty work under Zero's command, but their leader, Skull Face, grew to resent Zero and Big Boss for taking all the glory.

In Metal Gear Solid 5: The Phantom Pain, Zero orchestrates a rescue mission for the three survivors. Ocelot takes care of Big Boss and the medic during their nine-year coma, and he reluctantly carries out Zero's grand plan to create another Big Boss. Through hypnotherapy and plastic surgery, Ocelot convinces the medic that he is actually Big Boss. This copy will continue the legacy of Big Boss as the real one recovers behind the scenes. Called Punished "Venom" Snake, this character leads the successor to the MSF: the Diamond Dogs.

On the opposite side of the spectrum, Skull Face plans to use a parasite that targets only English speakers to rid the world of the language. He also has a nuclear-capable giant mech called Metal Gear Sahelanthropus under his command. What Skull Face didn't expect, though, was betrayal. A child soldier with psychic powers named Tretij Rebenok defected from the XOF, siding with a child soldier named Eli, who rebelled against the Diamond Dogs. These two would grow up to become Psycho Mantis and Liquid Snake. They take Sahelanthropus, but Venom Snake ends up destroying it. In the chaos, Skull Face gets pinned under rubble, at which point Snake, Miller, and a scientist named Huey Emmerich end his life.

The real Big Boss sets up yet another military state in central Asia called Zanzibar Land, where Metal Gear 2: Solid Snake takes place. FOXHOUND, now under the command of Colonel Roy Campbell, sends out Solid Snake, trusting him to infiltrate and destroy Zanzibar. This time, the stakes are raised. Big Boss has kidnapped a scientist who discovered a way to mass produce an oil alternative. He hopes to use his control over the valuable resource, along with a new nuclear-capable mech, as even more leverage against other countries, again in hopes to improve the treatment of soldiers around the world.

Part of Snake's mission includes rescuing the scientist, but upon reaching his destination, all he found was a corpse. Moving forward, he obtained the formula for the oil alternative and faces down Metal Gear D, which was controlled by Gray Fox. Fox reveals he has always held allegiances to Big Boss, and he suffers horrible injuries after Snake destroys the mech. In the final showdown, Snake burns Big Boss alive using an improvised flamethrower and escapes Zanzibar.

Snake retires from FOXHOUND, tired of these nightmarish missions. He hides away in the Alaskan wilderness, hoping to spend the rest of his days there. Meanwhile, the Patriots recover Big Boss' body, keeping him as alive as possible through cryogenic sleep and nanomachines.

Metal Gear Solid 2: Sons of Liberty happens four years after the Shadow Moses Incident. FOXHOUND recruit Raiden infiltrates an offshore facility called Big Shell, which was taken over by a terrorist group. The Big Shell Incident was meant to cover up the creation of Arsenal Gear, a giant mobile fortress that could launch nukes anywhere while deploying mass-produced Metal Gear RAY units.

Solidus, formerly a US president, orchestrated the event to challenge the Patriots, who at this point control everything in America. He flies Arsenal to New York City, using it as a distraction while he tries identifying the Patriots. His goal is to kill them and restore freedom to the people.

Additionally, Ocelot tells Raiden about the S3 Plan: the Solid Snake Simulation. Raiden's mission was a deliberate re-creation of Shadow Moses in order to make the ultimate soldier. Arsenal Gear crashes onto the streets of New York, atop which Raiden and Solidus fight each other. At that moment, Raiden gets a call from one of the Patriot AIs, who explains that the S3 Plan is actually called the Selection for Societal Sanity. The entire incident was a test to see how the AI Patriots could control everything during a crisis.

The Patriots hold Raiden's girlfriend hostage, goading him into killing Solidus. He slays the Big Boss clone, saving his girlfriend. Meanwhile, Snake gets his hands on the disc that identifies the Patriots, but he finds out they've all been dead for decades.

Liquid steals an Arsenal Gear-like ship from the Patriots and calls it Outer Haven (again). He outfits it with a Metal Gear REX railgun. Also aboard the warship is GW, one of the Patriots' AI systems. He hopes to use the railgun to destroy the Patriots' main AI core, named JD, and then take control of the Patriots' entire network via GW.

Thanks to the help of some scientists, Snake obtains a computer virus called FOXALIVE, which can destroy the SOP System. He infiltrates Outer Haven and uploads the worm to GW. In an unexpected turn, the virus goes beyond destroying SOP and affects the entire Patriots AI network, severing their control over everything in America.

Snake and Liquid have their final fistfight, in which Ocelot (who Liquid is possessing) starts showing more of himself. He reveals that his whole goal was for Snake to destroy the Patriots, starting his entire insurrection to draw attention to himself. After the fight concludes, Ocelot collapses and succumbs to his wounds.

After the credits roll, Snake finds himself at Big Boss' grave, about to commit suicide. At the last second, he doesn't go through with it, at which point Big Boss himself approaches, carrying his mentor's gun. Alongside him is the vegetative Zero, in a wheelchair. Big Boss pulls Zero's plug and reconciles with Snake, telling him it's "time to put aside the gun and live."
