UGSF/Ace Combat - Timeline

[Jozaca]

Explanation: In 2011 Namco released a timeline (it is down bellow) that revealed that lots of its past arcade games were set in the same universe. Not only that but the game Ace Combat 3: Electrosphere is the first in the timeline. Its unknown what that means, since Ace Combat 3 is the last game chronologically in the Ace Combat Timeline, so, either Ace Combat 3 is just part of 2 different universes, the rest of the Ace Combat games are omitted because they are not part of the "Space Era" that is unleashed because of the events from Ace Combat 3 (although the events of Ace Combat 3 doesn't really have too much to do with with space, in any case Ace Combat 7 or other game would be more appropriate) or they are omitting the other games because they don't want to directly imply that Ace Combat is a distant prequel to Galaga, Galaxian, Dig Dug, etc because some people might find it silly. On the other hand the Ace Combat games have a timeline that takes place across multiple wars between fictitious countries and continents. I think the first games actually implied that they take place in real world Earth, but starting with the fourth game they are clearly set in a parallel Earth. The Ace Combat Timeline is usually called Strangereal Timeline because an old trailer said something like "set in a strange, real universe" and the fans and later the producers decided to adopt it. Notice that the continuity/universe is called Strangereal but the planet itself is called Earth. This timeline is made by me assuming that the UGSF and Strangereal timelines are indeed the same. If someone is trying to play them in chronological order, keep in mind that most of them except the Ace Combat games and the most recent releases have no real plot or ending or have the typical 80s arcade ending of 3 slides after finishing the game. By the way the Ace Combat timeline is super-detailed , so, I would try to add more dates when I have played more of them. I have only played 7, without the DLCs, so, I would update soon. Some of the UGSF games are unreleased games and others are mobile gatcha games that are no longer available. Also New Space Order (Unreleased game) seems to be about 4 galactic powers battling each other are the United Galaxy, the Military Empire, the Sacred Religious State and the State of Feudal Dynasty, in which the first one is the UGSF Earth but the other 3 are implied to be the planet Xevious, the planet from the Tales of... series and the planet from Mirai Ninja. However, other sources claim the Xevious series to be part of an alternate universe from the main UGSF...

Name Clarifications
There was a game called Air Combat in Japan for arcades, then that game got a sequel called Air Combat 22 also for arcades. Then a reboot/spiritual successor or whatever you call to call it was released for the PlayStation that was called Ace Combat in Japan but was called Air Combat for some reason in international regions. And then every game after that one got called Ace Combat following the numeration of the first one even if that one was not called Ace Combat in that region. Also for some reason the European releases seem to try to hide that they are sequels and don't feature a number at least until 6. The 3 in Galaxian3 is not a note, it is the title of the game

Air Combat (Know as Ace Combat in Japan)
Ace Combat Zero: The Belkan War (Known as Ace Combat: The Belkan War in PAL regions)
Ace Combat: Assault Horizon Legacy (Remake of Ace Combat 2)
Ace Combat 04: Shattered Skies (Known as Ace Combat: Distant Thunder in PAL regions)
Ace Combat 5: The Unsung War (Known as Ace Combat: Squadron Leader in PAL regions)

[Jozaca]

Ace Combat (Air Combat): The first one, released in PS1. Called Ace Combat in Japan and Air Combat in the rest of the world. Set in its release date.
Ace Combat Zero: The Belkan War: Despite what its name implies seems to be set between 1 and 2. The European release (and I guess the Australian one) drop the number of the title as all PS2 Ace Combat games.
Ace Combat 2/Ace Combat: Assault Horizon Legacy: The second one released in PS1. Assault Horizon Legacy is a remake for the 3DS. Strangely, there is a game called Ace Combat: Assault Horizon (Without the Legacy) that has nothing to do and is one of the few Ace Combat games outside of the main continuity. I am not sure about this but maybe the original 2 has references to being set in the real world and they were removed from the 3DS game to make it tie in to the Strangereal continuity.
Ace Combat 04: Shattered Skies: The first game released for the PS2. Called Ace Combat: Distant Thunder in PAL regions.
Ace Combat 5: The Unsung War [Arcade Mode]: Apparently arcade mode is located here.
Ace Combat 5: The Unsung War: The second game released in the PS2. Called Ace Combat: Squadron Leader in PAL regions. A digital PS4 version was included in the Deluxe Edition of Ace Combat 7, but it is sadly no longer available.
Ace Combat 7: Skies Unknown [VR Mode]: I have not played yet but seems to be here.
Ace Combat 6: Fires of Liberation: This one was an exclusive for the Xbox 360, but is now retrocompatible with Xbox One. A digital copy for Xbox One was available with the Deluxe Edition of Ace Combat 7, but it is sadly no longer available.
Ace Combat 7: Skies Unknown: The latest entry released for PS4, Xbox One and Steam. I guess is also available in the next gen counterparts of the consoles.
Ace Combat X: Skies of Deception: More info would be added later.
Ace Combat Xi: Skies of Incursion: More info would be added later.

Ace Combat 3: Electrosphere: This is remembered as the best one, funnily is also the weirdest one. It is the only main game (not counting Zero, X and Xi and extra modes) that is set in a different date to its release date. Set in 2040. It has multiple paths that branch of and lead to 5 different endings. But all of that is in the Japanese version and in the international version the story is shorter and non-branching. There is a fan made patch that converts the game in a translated version of the original Japanese release. There isn't any Ace Combat game set after this, so, this is for now the ending of the timeline if you don't count UGSF. General Resource Limited and Neucom Incorporated make their first appearance. The United Government and United Galaxy, which were formed years later, were under their silent control for more than a 1,000 years.

2090
-Governments from each nation come together to find a solution to the population boom on Earth. This leads to establishment of the United Government.
-Within the same year, an order was placed to G.A.L.O.F. Corporation to build the Type-3 space island colony, "Uranus." Meanwhile, in an attempt to establish order under the United Government, the allied nation's military forces were dismantled and reorganized to create 4 prominent military forces under the United Government – the UGA (United Government Army), UGAF (United Government Air Force), UGN (United Government Navy), and UGSF (United Government Space Force). From its establishment, the UGSF becomes the primary receptacle of technology, which leads to the creation of the UGSF Special Attack Team, Cyber Commando.
-The University of GAIA is established 10 years later in 2100.

Cyber Sled: The first non-Ace-Combat game in the timeline. Battle events showcasing multi-legged tanks, also known as "VEHICLE ," appears.
Cyber Commando: G.A.L.O.F Corporation completes construction of humankind's first Colony (Island Three), "Uranus." Within the same year, rebels take arm to occupy "Uranus." With the looming threat of the colony being directed for impact, the UGSF deploys the UGSF Special Attack Team, Cyber Commando, to stop the rebel revolt. Within a year, "Uranus" was liberated from the rebels, and later abandoned.

2100-2200
-The Photon Drive, a propulsion engine in development since 2050, enters its release stage. It brought about a new age, the First Space Pioneer Era, where many interstellar spaceships were deployed to conduct research on star systems as far as 10 lightyears away. Spaceships traveled to the Alpha Centauri system (Toliman and Proxima), Epsilon Eridani system (Ozma), and the 61 Cygni system (Exia), where they discover planets capable of sustaining life (such as Corneus) or with terraforming attributes (such as Exia 2).
-In commemoration of these discoveries, the A.G. (After Galactic) epoch is born. This designation becomes common in use from 2100, next to the pre-existing A.D. epoch.

Burning Force: Hiromi Tengenji enters takes on the final exam to graduate from the University of GAIA's cosmonautics, "Top of the Space" course. After her graduation, she joins the UGSF.

2200
-The first space-time jump drive, "Warp Drive," is developed and enters its release stage. With it, humankind expanded their frontiers to the far reaches of the galaxy, paving way to the Second Space Pioneer Era. The term "Earthian" and "Galaxian" is born.
-Within the same year, the United Government is dissolved and reorganized to form the United Galaxy. As with the United Government, the United Galaxy based its operations on Earth.

Galaxian³: Project Dragoon: The very first contact with an extraterrestrial being was made in the Epsilon Eridani system. This "being" is later referred to as a "Live-Weapon," or more commonly known as the "UIMS" (Unknown Intellectual Mechanized Species). Within the year, the Cannon Seed on the planet Dogmas was destroyed, along with the Dogmas, leading to the retreat of the UIMS.

Galaxian³: The Rising of Gourb: A new type of UIMS, the UIMSΔ, invades the planet Corneus. Within the year, the UIMSΔ space fortress, "GOURB," and Corneus is destroyed, with the UIMSΔ taking flight in defeat.

2253
In order to face the extraterrestrial threat, the UGSF initiates "Project D." Various technologies obtained from the UIMS and UIMSΔ are evaluated and adopted into the UGSF. This made it possible for the UGSF to reduce the size, and increase the performance and firepower of the UGSF spacefighters. The technological application adopted became a long running standard used among future spacefighters.

Around 2260
The technology acquired from the UIMS made it possible for the United Galaxy to conduct large scale immigration across the galaxy, bringing about planetary modifications. As a result, 60 star systems came under United Galaxy order, with a total of over 40 billion in population residing within those star systems.

Galaxian: The United Galaxy comes in contact with aliens (the ETI or Extra-Terrestrial Intelligence) triggering the Galaxian-Galaga War of 2279. The small size and sheer number of the aliens made it impossible for the UGSF to employ their larger vessels of war. So instead, the UGSF deploys their proto-type spacefighter, "Galaxip." This move led to the defeat of the aliens, and since then, this approach becomes a standard measure employed by the UGSF for their operations.

Galaga: In just 3 years from the Galaxian-Galaga War of 2279, the Galaxian-Galaga War of 2281 begins. To face the aliens (codenamed "Galaga"), the UGSF prepares a defensive line to protect the solar system. Early preparations against alien attacks made it possible for the UGSF to finish development of a new spacefighter, "Fighter." The Fighter is equipped with Dual Fighter Mode technology to face the impending threat in place of the now defunct, Galaxip.

Bosconian:
Following Galaga, a new extraterrestrial lifeform, the ETI-2 (Next Extra-Terrestrial Intelligence), is discovered. These lifeforms created bases within the United Galaxy star systems, and quickly began occupation of their surrounding territories. In accordance to negotiation protocols, the United Galaxy tried to initiate friendly contact with these lifeforms, followed by a warning, and finally intimidation, to all being replied with force. The UGSF completes their analysis of the enemy force, and codenames them "Bosconian." With the analysis complete, the UGSF moves to deploy their means in facing the Bosconians, the "Blaster" spacefighter. Within the same year, the Bosconians abandons and retreats from their bases within the UGSF star systems. These abandoned bases are claimed by the UGSF, and through research of these facilities, the UGSF gains further information regarding the Bosconians. Not making waste of these bases, the UGSF incorporates them for their use.

Gaplus:
After experiencing the Galaxian-Galaga War of 2279 and the Galaxian-Galaga War of 2281, the Galaga forces quickly evolve into a higher intelligent form - a third generation of aliens called the "Gaplus." The Gaplus proceeds to create a new empire under their rule. The UGSF, fearing the rise of the alien force, develops a new spacefighter, the "Ogre Header," which is designed to utilize powerful weapons collectively called "Blaster Heads." Recognizing this threat, the Gaplus steals the Blaster Heads, which marked the beginning of the Galaxian-Galaga War of 2283.

Galaga '88:
The UGSF thwarts the threat of the Galaxian-Galaga War of 2283, but the aliens have evolved to a point where they can use "Hyper Drive," a dimension jumper. After building their base of operations, the aliens begin their assault on Earth using Hyper Drive. In response, the UGSF takes defensive action to protect Earth from the spawning aliens. After successfully defending Earth from the aliens, the UGSF discovers that the surviving aliens have retreated through a dimensional hole. With this discovery, the UGSF creates a plan to defeat the aliens and to destroy the alien's base of operations, "Planet Galaga." Assigned to the mission was the spacefighter, "Blast Fighter," equipped with Triple Fighter Mode technology. Within the same year, Planet Galaga falls to the UGSF, and from its remains, the UGSF discovers the technology behind Hyper Drive.

Blast Off:
The second wave of Bosconian attacks commence. This time, the Bosconians weren't the only threat. Looming behind the Bosconian attacks were the "Battura," who would appear hundreds of years later to lay siege against humankind. Sensing that there is something peculiar with the Bosconians, the UGSF deploys their latest spacefighter, the "Blaster FR." With its deployment, "Operation: Blast Off" commenced.

Final Blaster:
The Galaxian-Bosconian War of 2290 begins, and spreads its threat to Earth. Noting the gravity of the threat, the UGSF activates "Operation: Final Blaster." They deploy their newest spacefighter, the "Blaster Mk2 Phoenix," that was developed to face the Bosconians.
- Within the same year, the enemy's planetary frontline, "Planet Bosconian," falls under the UGSF's attack, leading to the retreat of the Bosconians. During the alien and Bosconian wars, the United Galaxy begins restoration of their battle-ridden planets. General Resource Limited establishes an intergalactic band of mercenaries called the "Bounty Hounds" to rid of any remaining alien threats. 8 planets under the United Galaxy's star system are set with an interstellar computer cluster system called the "FEDCOM," which were put to use.


Bounty Hounds:
During the Second Space Pioneer Era, continued attacks by extraterrestrial lifeforms left many planets in ruin. A mercenary assigned to the Bounty Hounds is dragged into the conspiracies between two mega-corporations, "General Resource Limited" and "Neucom Incorporated," who have been in conflict before the age of space pioneering.

Galaxian³: Attack of the Zolgear:
A space lifeform known as "Zolgear" arrives on the planet Exia, which was going through terraforming since the beginning of the First Space Pioneer Era. Unlike the initial discovery of Zolgear in 2298 (Bounty Hounds), this Zolgear was much larger, and it lands near the environmental control center where it begins its assault. To face this threat, the UGSF Special Attack Team is deployed on board the tactical spacefighter, "Dragoon J2."
Within the same year, they defeat and liberate Exia from the Zolgears.
5 years later, the Bussard-Ramjet Drive Dragoons were retired from action.

StarBlade:
The third wave of alien attacks are led by humankind's nemesis, the UIMS. The UGSF takes defensive action, activating "Operation: Starblade." With the retirement of the Dragoon J2, the UGSF loses their means to operate long distance strikes. Instead, they form a new fleet, "Team Starblade," comprised of their latest spacefighters, the "FX-01." Within the same year, Team Starblade's right wing force, the "GeoSword Flight," defeats "Red Eye," "Iceberg," and "Commander." The UGSF discovers the technology to control Quasar from the remains of "Commander."

2340-2400
Attacks from extraterrestrial lifeforms cease, and an era of stability is ushered in to the United Galaxy. Incidents of note only occur within the United Galaxy's star systems.

Dig Dug:
Among the star systems under the United Galaxy's rule, a planet is invaded by monsters appearing from underground. To help defend the planet, Taizo Hori comes to the rescue.

Dig Dug II:
Among the star systems under the United Galaxy's rule, an island on a planet is invaded by monsters. Taizo Hori, the hero who saved the day in the previous Dig Dug incident, comes to the rescue again.

Baraduke:
A distress call is received from the outskirts of the United Galaxy's star system. The call for help is sent from a group of peaceful extraterrestrial lifeforms called the "Paccetian." The vicious "Octians" built an underground fortress, the "Baraduke," where the Paccetians are held captive. To answer the call of distress, the UGSF sends in Masuyo Tobi from the UGSF Space Cavalry to save the Paccetians, and to defeat the Octians and Baraduke.

Bakutotsu Kijutei - Baraduke II: 3 years have passed since the Baraduke incident, but peace did not last long as the Octians has risen once again. With their second coming, the UGSF officially deems the Octians from being "mere savages" to "threats" to other lifeforms. Masuyo Tobi is ordered to face the Octians again, this time to finish them for good.

Mr. Driller: Mr. Driller main character is the son of Dig Dug and Baraduke main characters. Susumu Hori, son of Taizo Hori and Masuyo Tobi, who holds the title of "Mr. Driller," moves to action to solve the "Block Overflow Incident of 2399."

Star Trigon: Wataru Hoshi of the UGSF Astro-Rescue Team and Chuta Bigbang tries to solve the spaceship crashes that were occurring on a planet in the United Galaxy's star system.

Star Luster:
The UGSF identifies a third new threat - the Battura. The relative peace the United Galaxy was enjoying delayed updates to their spacefighters. Using this to their advantage, the Battura takes control over many of the star systems under the United Galaxy. The UGSF tries to buy time to rush development of a new spacefighter equipped with the latest in technology. This brings about the spacefighter, "G.A.I.A.," that is equipped with the latest in transport drive technology, the "Quasar Drive (black hole drive)," and a long distance jumping drive, the "Hyper Drive (quantum teleportation drive)." Upon its completion, "Operation: Star Luster" commenced. Within the year, the Batturas are defeated, and their mobile vanguard fortress, "Dark Planet," is destroyed. After their retreat, the UGSF discovers from the Battura's remains a technology that the UGSF could not achieve – the Diastasion reactor technology.

Star Ixiom:
With the United Galaxy weakened from Operation: Star Luster, a full scale attack is orchestrated by the extraterrestrial lifeforms. The UIMSΩ, Galaga, Battura, Bosconian, and a new extraterrestrial lifeform, "Sadeen," begins their invasion. With this unprecedented crisis falling upon humankind, the UGSF initiates "Operation: Star Ixiom," where spacefighters from the past and present are brought together to face impending threat.
With the success of "Operation: Star Ixiom," the mobile planet controlled by each extraterrestrial threat were destroyed, but the threats themselves dispersed from the frontlines of battle and began their infiltration into the many star systems under the United Galaxy. Furthermore, a third of the United Galaxy's star systems were either lost or destroyed from the attacks. Worse still, Earth is infiltrated and soon falls to the UIMS. With the loss of Earth, the United Galaxy moves to a new planet to call their home. This planet is called "Gaia," and is the fourth planet within the Cosmo-Lagoon system.

2489
A clan of Bosconians weakened by Operation: Star Ixiom raises a nation called "Bosconia." Soon after, the nation surrenders to the United Galaxy and becomes a part of the United Galaxy.

2500-2600
"Project D 2nd," a program to strengthen the United Galaxy through the course of a 100 years, is put to operation. The United Galaxy establishes a new star system with Gaia as their capital planet. During this time, advancements were made in the field of Diastasion science.

Mizuiro Blood:
Mizuiro Blood is staged on Earth under UIMS control. The UGSF sends in a fleet to conduct research on the status of the UIMS. Through this, the UGSF makes a shocking discovery. They come to a conclusion that, if the United Galaxy's powers are a "1" then the UIMS on Earth would be "less than 0.1"... After deliberations by the United Galaxy, "Operation: Dreadnought" is put into effect to remove the UIMS from the galaxy.

Mizuiro Blood (The Blog):
An official blog by Mizuiro Blood is released which gives insight on how "Operation: Dreadnought" was seen by the UIMS. Within the same year, over 1.04 million space vessels are sent to Earth to regain control. The operation succeeds, and Earth returns to the United Galaxy's control. Immediately after, an all-out attack is orchestrated against the UIMS, Galaga, Battura, Bosconian, and Sadeen forces within the United Galaxy's star systems.

StarBlade: Operation Blue Planet:
The final era in warfare begins. The remnants of the UIMS converge to invade Earth. To counter their invasion, "Operation: Blue Plant" is initiated. Within the year, codename "Mega-Mouth" and the flagship "Commander" are destroyed, thus ending the operation. The enemies were eradicated, but in exchange, the UGSF loses 97% of their fleet which were constructed during "Project D 2nd."

2660
An era of peace begins for the United Galaxy as they restart their plans to expand their influence across the star systems. During this time, the "S.T.A.R. Line," an energy tube used for interstellar transfer of inorganic materials, enters its release stage. The S.T.A.R. Line connects the star systems under the United Galaxy's control, and brings about a revolution in transit technology and economy.

2700
With the installation of the S.T.A.R. Line technology, the United Galaxy's star systems show explosive growth. By the end of 2700, territorial control expanded across 5,000 lightyears from the capital planet, Gaia.

Shin-Gun Destroy! Girl's Tank Battalion:
Neucom Incorporated schemes behind the United Galaxy to conduct unofficial experimentation of the Dimension Warp Drive through the 5th generation interstellar computer cluster system, FEDCOM5's control processing unit, "Root Unit 'Type Yellow' (R.U.T.Y.)." Within the same year, the experiments fail, leading to the loss of "Type Yellow." With the loss of Type Yellow, weapon manufacturing and development control is transferred to General Resource Limited and to each of the corporations who were represented by Neucom Incorporated, thus promoting corporatocracy across the nations. With the loss of Type Yellow, the only remaining processing units are "Type Red," "Type Orange," "Type Green," "Type Blue," "Type Indigo," and "Type Violet."

New Space Order:
Within the United Galaxy's star systems lies a nation of threat, codenamed "Military Empire." The UGSF's contact with the threat triggers the Avonford Conflict of 2845. With the conflict in motion, those involved are dragged deep into the mires of battle, leading to the war known as The New Space Order War, which continues on until 3210. This game is an unreleased game but for some reason is included on the timeline, even if there are no plans for an uncancellation in the horizon. More weird is that this game seems to hint at other games being in the same universe but they have no been included here.

Thunder Ceptor:
The S.T.A.R. Line was only capable of transporting inorganic matter, but in 7650, advancements in technology brings about the "Hyper-Way," an evolution to the S.T.A.R. Line which enables transport of organic matter. Meanwhile, battle ensued between the UGSF and aliens. With the aliens at an advantage, the UGSF develops the ultimate weapon, "V-28," but the energy necessary to run the weapon, "Geltorium," was under enemy control. It was then the UGSF pilot by the name of "Jimlitter" gained access to Geltorium. With fate on his hands, he navigates his Hyper-Way spacecraft, "Thunder Ceptor," through enemy fields to deliver the precious resource to the UGSF headquarters.
