Metal Gear Solid Volgorde

Metal Gear Solid Timeline – Everything in Chronological Order

The Metal Gear Solid Timeline has become quite complicated. The series is known for its complicated story full of intrigues and plot twists. Its creator Hideo Kojima does not make it any easier by jumping back and forth through time. The player often encounters (or plays as) family members of previous known characters, looking the same and even being voiced by the same voice actor. Although the video games cover the entire Metal Gear Solid Timeline, some stories were adapted into books, comics, or other media. There is even a Metal Gear Solid movie in the making. To put everything in perspective, we’ve divided the Metal Gear Solid Timeline into different eras, each era corresponding to a main game.

The Metal Gear Solid Timeline was last updated in July 2022.

Please note that the Metal Gear Solid Timeline contains spoilers for all installments in the series. The Metal Gear Solid Timeline is intended as a reference to put the titles into perspective. However, we do not go into much detail, so the games should still have more than enough surprises to offer if you have not yet played a specific game.

Metal Gear Survive was developed after Hideo Kojima had already left publisher Konami. Therefore, the events in Survive is not considered canon by many fans. Yet, the game is directly related to the main series. As it is the last Metal Gear released to date, there is no other media that contradicts or retcons the events in Metal Gear Survive. Thus, we can still treat is as part of the main Metal Gear canon. Unlike the main games, Survive is not a stealth game: it’s a survival game with zombies.

In the aftermath of the destruction of Mother Base during the Ground Zeroes Incident in 1975, part of the base is sucked into a parallel world through a wormhole. The player, an unnamed soldier, is later sent to this world as well. Here the player must survive amidst zombies and other strange creatures, and find a solution to the zombie infection. To accomplish his mission, the nameless soldier uses, among other things, a Metal Gear that also ended up in the parallel world.

Spin-offs

Metal Gear Acid

The status of some events in the Metal Gear Solid Timeline are heavily disputed, especially by fans. There are also numerous events depicted in games that are definitely not part of the main Metal Gear canon. A brief overview:

1995 – The Outer Heaven Uprising as depicted in the Metal Gear edited or NES version

This version of Metal Gear was originally released in 1987 for the NES, and later also released on PC and Commodore 64.

The original Metal Gear was modified quite a bit for the NES. So much, in fact, that this iteration is not considered canon. For example, the titular Metal Gear was dropped from the game. Instead, Solid Snake infiltrates Outer Heaven to destroy a ‘Supercomputer’.

  • The story of this version of Metal Gear was also adapted into a book by Alexander Frost and published as part of the Worlds of Power series
  • In Japan, the Metal Gear Gamebook, a continuation of the NES version of Metal Gear released by Konami, was released in 1988

2016 – Lobito Island Incident

The Lobito Island Incident is the main focus of Metal Gear Acid, sometimes written as Ac!d. The game was released in 2004 for the PlayStation Portable. It was later also ported to some cell phones.

Text continues below ad:

Metal Gear Acid is a true spin-off. Instead of a stealth game, it is a turn-based strategy game in which you use trading cards to determine your actions. In Metal Gear Acid, a senator has been taken hostage by terrorists, and Solid Snake is sent to rescue him. Snake must also destroy the Metal Gear KODOQUE. This Solid Snake is an alternate version of the hero from the main games, and Metal Gear Acid has no ties to the main games.

Somewhere after 2016 – Metal Gear Acid 2

Metal Gear Acid 2 was released in 2005 for the PlayStation Portable.

Metal Gear Acid 2, like its predecessor, is a turn-based strategy game. A clone of that game’s Solid Snake is tasked with infiltrating a research facility. While there, he encounters Metal Gear Chaioth Ha Qadesh, which he obviously destroys.

Metal Gear Solid Mobile

Metal Gear Solid Mobile was released in 2008 for various cell phones, including the Nokia N-Gage

Metal Gear Solid Mobile is a mobile game similar in gameplay to Metal Gear Solid 2 and 3. The story takes place between MGS1 and 2 when Snake and Otacon first track down the Metal Gear REX. Metal Gear Solid Mobile’s place within the series is highly disputed. Although clearly related to MGS2, the game has never been recognized as canon by Hideo Kojima or Konami.

Metal Gear Solid: Social Ops

Metal Gear Solid: Social Ops was released in 2012 for iPhone and Android phones.

Metal Gear Solid: Social Ops is a game for smartphones. The story is based on the events from Metal Gear Solid 3: Snake Eater and Metal Gear Solid: Peace Walker, yet the gameplay is more similar to that of the Metal Gear Acid games.

  1. He does not kill big boss he kills Ahab or better known as venom snake. Not big boss the outer Haven in Metal Gear 1 is not really outer haven. People were hunting big boss who wanted to destroy him and what he stood for. So he chose to make someone look just like him and think just like him. This way they would hunt the doppelganger instead. instead of himself.

    1. everything except the ur first line is wrong, people or say other nations were after him because outer haven was becoming powerful with nuclear power which other superpowers didn’t like that’s why they were after him, and big boss wanted to threat the world with his power and make a world where soldiers are respected, that was kinda evil you know, also the outer haven in mg1 was actually outer haven and not just something big boss setup to fake his death, big boss wasn’t expected that solid snake would succeed in the mission, bb intended to capture snake or get him killed
