Girls' Frontline and Project Neural Cloud

Due to inconsistencies between medias, in-game sources (primary sources) and out-of-game sources (secondary sources) are presented separately. In the absence of official comment regarding inconsistencies, readers are invited to make personal conclusions based on the data presented.

In-game sources

Due to in-game inconsistencies, the following list attempts to present a least inconsistent timeline. See the dedicated subsection for a list of ignored time markers.

2062

• Chapter 0 to 4: AR Team breaks into Safe House 3 in Sangvis Ferri territory and disperse to escape enemy troops. The team is eventually assembled again thanks to the Commander.

Ambiguous timeframe (2062 to 2064)

• Chapters 5 and 6 and Operation Cube: Sangvis Ferri troops invade Area S08 and try to take down G&K's high command. The Parapluie virus is discovered in ^AR ST AR-15ST AR-15ST AR-15 and she flees to track down Elisa by herself. During G&K's counterattack, G&K enlists Squad 404 to support their operations in the nearby Area S06 under Operation Cube and ^SMG UMP45UMP45UMP45 becomes covertly infected with Parapluie. The conflict in Area S08 ends when AR-15 destroys Elisa's local dummy in a suicide bombing.
• Chapter 7: The Commander is transferred to Area S05 before they are forced, along with ^SMG RO635RO635RO635, to defend the T-Dolls gathered for Parapluie screening in the local G&K containment facility against Dreamer. ^AR M4A1M4A1M4A1 becomes catatonic after encountering Elisa during the attack. AR Team is subsequently sent after Dreamer's base in Area S05.
• Arctic Warfare: AR Team's aircraft crashes in a Sangvis Ferri Jupiter Cannon testing field in Area S03. G&K launches Operation Hypothermia to recover them.
• Chapter 8: G&K launches a covert ops on Sangvis Ferri's Base 0 to recover File No 7 and lose ^AR M16A1M16A1M16A1 to Sangvis Ferri due to Parapluie. M4A1 emerges from her coma.

2063

• 23 December: Project Neural Cloud's story begins with the Sanctifier assault on Oasis.

Official timeline of the Singularity event.

2064

• Between 2051 and 22 May 2064, Lady Gray is killed and replaced by a Nyto double, drastically altering the direction of her research on biotechnology.
• Deep Dive: Squad 404 is deployed by G&K to recover the data drone launched by M16A1 before she was taken over by Parapluie. They catch wind of the chaos unfolding on G&K's side as they finish the operation.
• Chapters 9 & 10, Singularity and Continuum Turbulence: 20 months after AR Team separated at Safe House 3 and about two years after the start of G&K's contract to destroy Sangvis Ferri, G&K and the KCCO lead a joint assault to end the threat of Sangvis Ferri. During the battle, the KCCO fails to force the awakening of Elisa's OGAS consciousness and most of their forces abandon the field, leaving G&K's troops to retreat under fire and arresting Kryuger on various false charges as cover. This is called the Great Retreat.
  • AR Team takes part in the assault but M4A1's neural cloud is attacked by Elisa. Captain Yegor eliminates ^AR M4 SOPMOD IIM4 SOPMOD IIM4 SOPMOD II and ^SMG RO635RO635RO635 as KCCO attempts to use M4A1 to awaken Elisa's OGAS. M4A1 is rescued, enhanced and recruited by Task Force DEFY. SOPMOD II's mangled body is later reactivated by M16A1 and she recovers RO635's data core before rejoining with the fleeing G&K forces.
  • The Bureau of State Security tasks DEFY and Angelia to recover Elisa before the KCCO and find proof of their plan to use OGAS to trigger a new World War. Angelia hires Squad 404 to help locate Elisa through the Parapluie jamming.
  • M4A1's OGAS promises her to reveal the location of SOPMOD II and M16A1 so she can rescue them, if she encounters Elisa first. Agent nearly kills the Commander before Angelia asks to spare their life in exchange for a new encounter between M4A1 and Elisa. As a last resort against Yegor's forces trying to capture Elisa, Havier Witkin airdrops Angelia a set of Collapse bombs.
  • A third faction, Paradeus, makes itself known on the battlefield, attacking remaining G&K forces.
  • M4A1 rejects Elisa during their encounter and Angelia orders M4A1 to detonate the Collapse bombs to counter Yegor's inbound forces. M4A1 and ST AR-15 pursue Elisa but she is airlifted from the battlefield by M16A1. M4A1 and ST AR-15 are left stranded in enemy territory and manage to evade the Paradeus forces with the help of M4A1's OGAS.
  • While the majority of the G&K forces evacuate the area after repelling a Paradeus assault, a contingent of volunteers assist DEFY in evacuating Angelia, but the Commander is captured by Paradeus.
  • Nine weeks after the end of the Great Retreat, the Commander has recovered from Collapse radiation poisoning and is interrogated by Paradeus. They are soon recovered by Squad 404 and delivered to G&K. Under pressure, they accept to work for the Soviet Bureau of State Security.

• Chapter 11: Five months after the joint assault and three months after their return, the Commander mans a search mission for Angelia in Belgrade and partners with a local informant.
• Isomer: A Neo-Soviet—Pan-European meeting is held in Belgrade ahead of the United Nations vote on Rossartrism in May. The meeting is interrupted by a Paradeus assault, plunging Belgrade into chaos. Angelia, K and G&K successfully evacuate Gilda Ulrich and eliminate Mercurows, while the local Pike node is seized by M16A1, who empties it of data and leave it to be recovered by G&K, who then cedes it to Soviet Statesec.
• Shattered Connexion: Angelia and G&K are deployed to the Paldiski Submarine Base, a Paradeus lab, with the aim of reaching it before KCCO. While crossing Tallinn, which has become a Paradeus "dump site" for unwanted Nytos, M4A1's OGAS consciousness hijacks Nimogen's body and receives the name Dandelion. G&K repels a KCCO assault and steals a KCCO armored train.
• Polarized Light and Chapter 13: Paldiski Incident.
  • Prior to the arrival of other belligerents, Sangvis Ferri troops invade the Paldiski base for Elisa to use the local Starfish.
  • G&K sacrifices most of its troops and K negotiates a Neo-Soviet air strike to prevent the KCCO from entering the base.
  • Angelia and Squad 404 evacuate assets from the Paradeus lab inside the base.
  • Two Sinner mechs, including one piloted by Yegor, break through the G&K blockade to reach the labs. One is destroyed by M16A1 and M4A1, Yegor's is destroyed by Angelia and Task Force DEFY.
  • The Commander and K plant explosives on the base's sea valves to flood the labs and the Starfish. M4A1 confronts M16A1, then Elisa, and merges with her OGAS consciousness to engage a Reverse Collapse and teleport all present to an unknown location to escape the flooding.
• Dual Randomness: Starting 13 September, Angelia investigates the presence of William and Paradeus in Bremen, Germany. Simultaneously, G&K investigates other leads on Paradeus and encounters several former Sangvis Ferri Ringleaders who are then marked for capture by Svarog Heavy Industries.
• Mirror Stage: On 17 September, Angelia is brought to Berlin by the Stasi. On 20 September 2064, the Commander captures Machlian in Bohnsdorf. In the following days, they foil several Paradeus terrorist attacks around Berlin and fall into Morridow's trap to capture Dandelion, while Angelia investigates Lady Gray and is captured by Paradeus at the von Oberstein mansion in Berlin. Angelia arrives at Avernus on 16 October.
• Poincare Recurrence: In early October, the Commander and the Stasi intercept a cargo of Iaso's Boxes leaving Berlin, but fail to find Angelia and lose their hostage Morridow. On the night of Unity Day in germany (3 to 4 October), rebel special forces troops in the Neo-Soviet Union cause the Fireworks Incident at the Western border and destroy Griffin & Kryuger's HQ, but fail to kill Griffin's leadership.
• Fixed Point: Griffin & Kryuger and the Stasi launch Operation Aeneas in the Berlin Dead Sea Black Zone to investigate the Paradeus base Avernus and rescue Angelia.
• Eclipses & Saros: On 20 October, as Operation Aeneas is ongoing, the Commander and the Stasi each secure one of the two surviving members of Daybreak Squad in preparation for Operation Muromets.
• Longitudinal Strain: Operation Eclipse takes place on 20 October. Statesec sends Instructor Я to the Commander for Operation Muromets. Я rides in the Intercontinental Railway, where she meets Erma, another creation of Arthur Hume, and foils a Vory v Zakone armed robbery. Despite multiple opsec precautions, Paradeus identifies her and derails the train with help from the KCCO. Я is destroyed when protecting the passengers, but her neural cloud is backed up in Erma's and delivered to the Commander.
• Slow Shock: During Operation Muromets to rescue Angelia from Avernus, several high-ranking Nytos are eliminated but the operation runs out of time. William is captured by Task Force DEFY during the concurrent Operation Kriemhild, Avernus is destroyed by an air bombardment and Angelia is MIA. The mission ends on 23 October 2064.
• The Summer Garden of Forking Paths: Just after Slow Shock, the Commander, Dandelion and William disappear. Following a lead, the Elmo travels from the Black Sea to Frankfurt. ^SMG ErmaErmaErma sacrifices herself to destroy the Summer Garden and prevent mankind from using GRCh38.
• Zero Charge: The forces of StateSec, the Stasi and the remnants of Paradeus converge in Frankfurt. On 31 October, Task Force DEFY kills Embla.
• Angular Gyrus: On 1st November 2064, the Interim Regulations for Doll Security is implemented in Berlin and Frankfurt. Over the next two days, the Commander is rescued and kidnaps Lunasia, and Paradeus starts Operation Cocoon in Frankfurt.
• Isolation Forest: Gray is reanimated under the Commander's orders by Nele. Concerted efforts by the Commander, Statesec and the Stasi prevents the deployment of Iaso's Boxes in Frankfurt.
• Convolutional Kernel: Coronation Storm begins and Frankfurt is bombarded by General Carter's forces on 15 November at 20:30. Carter is killed on 18 November and the Battle of Frankfurt ends soon after. The Union of Rossartrism Nations Coalition (URNC) is formed, Lunasia's vessel is destroyed and the Commander disappears.
• Roche Limit: Two days after the Commander's disappearance, Kalina enters Frankfurt to investigate, inadvertently leading to the Commander's capture by the Prometheans.
• 30 December: Griffin Lyons writes a letter to an unidentified next-of-kin of the Commander to announce their death in Frankfurt.

Inconsistencies

This is a list of time markers appearing in various stories that have been ignored to preserve the consistency of the preceding timeline.

• Girls' Frontline (It should be noted that in-game dates and time markers of Girls' Frontline do not match with the real-world time on which chapters have been added to the game. As in: a chapter added to the game a month after the previous one does not take place a month later in the story. Also note that the numbers associated with Bee Sting entries used as story backgrounds are not internally consistent and thus always ignored.)
  • Chapter 0-1: AR Team is assembled a month after separating at Safe House 3.
  • Chapter 2-5: M4A1 was on the run during at least 70 days after separating with AR Team at Safe House 3.
  • Operation Cube 1: Operation Cube starts five days after AR-15's disappearance.
  • Chapter 7-1: Five days after the end of the battle in Area S08, the Commander is transferred to Area S05.
  • Chapter 7-1E: A month after the assault on Area S05, AR Team is sent after Dreamer's base.
  • Arctic Warfare 1-1: Arctic Warfare occurs 40 days after Dreamer's assault on Area S05.
  • Arctic Warfare 2-3: Arctic Warfare occurs 6 months after Operation Cube.
  • Chapter 8-1: AR Team's infiltration of SF Site 0 occurs two months after Arctic Warfare.
  • Chapter 9-1: The Great Retreat takes place a week after the mission at Base 0.
  • Deep Dive E2-2: The Great Retreat takes place a year after Operation Cube.
  • Singularity Queens Gambit III & Minor Pieces Draw IV: These two chapters contradict each other regarding when Angelia was nearly killed by Sangvis Ferri during the Safe House 3 events, respectively indicating one year and two years prior. Poincare Recurrence - Reversing Entropy VIIA later fixes tis event to 2062.
  • Isomer Illusory Peace I: Isomer occurs two years after the 10 years celebration of the end of World War Three (“前两年格外盛大的第三次世界大战结束10周年纪念活动。”), which would make Isomer take place in 2062 or 2063 since the war ended in 2050 or 2051. But Isomer takes place after the Great Retreat, which occurred in 2064.
  • Dual Randomness Departure Time III: Dual Randomness occurs nearly 20 years after the end of World War Three. This is a translation error, the original script states “more than 10 years”.
  • The train ticket appearing in the main menu of Longitudinal Strain bears the date “20640717”, or 17 July 2064. Considering that Longitudinal Strain takes place after Fixed Point, this date is too early by a minimum of five months.
  • The Dedicated Tactical Memory equipment, available during the Christmas 2017 event running 21 December 2017 to 11 January 2018 on CN, mentions 2063 in its description. Because Story Chapter 10 was added with the same update on 21 December 2017, one could infer that Chapter 10 takes place in 2063. However, this is inconsistent with chapter 10 taking place during the same timeframe as Singularity, which is stated to be taking place two years after 2062.
  • Because of inconsistencies and overall dubious canonicity of the source, dates appearing on the Notebook mementos are not used as reference to infer the dates of other events:
    • The Prairial’s Allure banner for the Anniversary Party costumes story ran from 20 May to 1st June 2017 on CN, between the releases of Chapter 8 and Deep Dive, and mentions both 2063 and 2017 on the title banner.
    • The Princes’ Frontline banner for the Fatal Performance costumes story ran from 28 November to 7 December 2017 on CN, between the releases of Chapter 9 and Chapter 10. It mentions 24 March 2063 on Thompson's ticket (the date is erroneously rendered 34 March 2063 on PKP's restaurant bill).
    • The Sweet Imprints banner for the Honey Sweet Moment costumes story ran from 10 to 22 March 2018 on CN, between the releases of Singularity and Continuum Turbulence, and mentions 11 March 2063 on SV-98's invitation.
    • The banner for the Christmas Eve Express costumes story ran from 22 December 2018 to 10 January 2019 on CN, between the releases of Chapter 11 and Isomer. It mentions 2018 on PX4 Storm's coupons.
    • The Soiree Sonata banner for the Symphony No. 4 costumes story ran from 14 May to 11 June 2020 on CN, between the releases of Chapter 13 and Dual Randomness. It mentions 2064 on KSVK's size chart and 20XX on M200's photo.
• Project Neural Cloud
  • In Divergent Shadows Stage 2-4, Clukay (HK416) reminisces about the events of Continuum Turbulence (in the Chinese script, dialogues are copied word-for-word between the games) while in her pre-Neural Upgrade appearance, implying the story occurred between the Great Retreat and the events in Tallinn, during the timeframe of Chapter 11 and Isomer in Girls' Frontline. However, Divergent Shadows is also set before Project Neural Cloud's main story, which begins on 23 September 2063 according to Chapter 0-1 and Engrammatic Eclipse Part 2. This contradicts Singularity Minor Pieces Draw IV, which determines that Continuum Turbulence occurs in 2064. This story is not accounted for in the previous section because Divergent Shadows Parts 1 and 2 establish its own loose canonicity.
  • In Gloaming Finale, the Professor/the Commander claims they've been in Magrasea for three years. Regardless of whether they entered in 2063 or 2064 (see above), they wouldn't have been able to be in Magrasea for this long due to the events leading to and following the Battle of Frankfurt in November 2064. It's not specified that three years actually passed in the real world, and an unspecified amount of time differential exists between the real world and Magrasea, but it is also known that over three real-time months elapsed between the Professor entering Magrasea and the Sanctifier attack on the Oasis.
  • The Steins;Gate collab event is said to take place on 21 December (no year specified), and occurs after the Entropic crisis. This is not consistent with dates provided in Engrammatic Eclipse.

In Slow Shock

Slow Shock Part 1 present alternate worlds and so all events taking place in it need to be confirmed by other sources to be considered valid. This affects the following events:

• “Anna” route: Operation Eternal Flame in Beslan in winter 2047. Angelia meets Martha Meitner.
• “Junior Lieutenant Angelia” route: The clash between Soviet troops and the support forces of Operation Couatl outside Avernus in spring 2051, including Ramzan's death and the encounter between Angelia and Meitner. The events are said to occur on an island in the Pacific, but also in the Dead Sea, which every other source locates in Germany and where Operation Couatl has taken place according to Eclipses & Saros. The chapter ends with the implication that either Meitner or Angelia was killed, neither of which could have happened.
• “Commander Angelia” route: Angelia's stint at Griffin and Kryuger in summer 2061, her escape after being accused of murdering Commander Novikov and the fight against Ganglati. There are many inconsistencies: in Sunlight in the Blue Room, LAMG claims she has been serving with Angelia for years at the time of the murder, but in The Angelus, it is also claimed that the serial murders of G&K employees (2060 according to the first artbook) was the year before, which would place Novikov's murder in 2061, the same year Angelia joined. Moreover, according to ^AR AN-94AN-94AN-94's Neural Upgrade story, AK-12 was rolled out on 12 February 2062, so the events of Angelia fleeing G&K with AK-12 and AN-94 cannot have happened in 2061. Finally, it is known that Angelia parted ways with Griffin during the events of Safe House 3 in 2062, not because she was accused of murder. Kryuger also claims that the inability of Dolls to backup and transfer their memories is an issue soon to be resolved, but the Neural Cloud system was already in place by 2060.

The fourth and final “Agent Angelia” route is unambiguously presented as an alternative version of the events in Germany in autumn 2064, where DEFY doesn't enter Bremen but goes to Berlin on their own accord, Q is revealed as a double agent, Angelia isn't captured by RPK-16 and Gray, the Stasi turn on Angelia, the Commander is killed and Dandelion is captured by Paradeus.
