The Great Decisive

The Great Decisive was a failed invasion of Earth by the Inimics, with heavy defenses by the indigenous Humans from 2026 to 2027.

### Prelude

###### Inimic Perspective

According to the Sagittarian Palnygara-Refforma, Inimics chose Earth for infestation due to the amount of biomass they could harvest, plus the atmosphere which could be converted to their native Methane-Oxygen mixture, detecting the humans around 2005. From here, they started to bolster their forces in preparation of an invasion of the planet from an unknown star system at least 115 light years away. Eventually, around 2012, their military forces were ready and multiple hive ships were sent towards Sol.

###### Sagittarian Perspective

The Sagittarians, who have been attempting to annihilate the Inimics, detected the Inimic invasion fleet from orbital satellites as they were heading towards Earth. The Sagittarians, being hundreds of light years away, knew that they wouldn’t make it to the Inimics before they reached Earth, but proceeded anyways with a battlefleet to defend life there as Inimics only conquered planets with life on it to consume them for more resources. Eventually, the Sagittarians detected the presence of humanity as they approached Sol and detected their radio signals. Knowing that there was what would be their first other civilization, their priority was switched from killing the Inimics to defending humanity.

###### Human Perspective

The humans, totally unaware of the two races’ existence, continued to normally exist until the Inimics were detected in the Oort Cloud from the International Orbital Telescope Alpha (IOTA) in May 4th, 2026. Initially though to be a group of asteroids or comets, they were soon revealed to be alien fleets by the time they reached Jupiter. The United Nations announced this discovery to the public, followed by mass panic and religious sacrifices from the fear of a possible alien invasion after all probes seeking to get a better picture were destroyed. Militaries around the world were on high alert, uses of WMDs were debated, and armed militias around the world formed with global firepower increasing every day. As the Inimics came ever closer, they were spotted to make the Moon a temporary base to station their forces, with Mars being slowly terraformed. Weapons, food, and equipment were mass produced until the day the forces that would come.

### Contact and invasion

On June 22nd, 2026, the Inimics launched the invasion of Earth. Twenty-five capital ships took positions around the world as they launched Inimic soldiers and bombarded the terrain, with the Inimic Queen leading the hive-minded fleet on a large base on the moon. The humans, who had prepared for their arrival, met them for the first time in Jakarta, Indonesia. When a team of linguists and psychologists attempted to discover their intentions, they attacked them, prompting the humans to fire back in return. That was the first battle of The Great Decisive, known as the Battle of Jakarta. Within days, Jakarta fell. As militaries around the world struggled to fight back the massive amount of Inimics, countries fell and half of the world’s nations collapsed within a month. On this course, humans were on the course to extinction, until a weak point was spotted by scouts and survivors in Oakland, a city in America. On July 6th, a world convention was signed to use nuclear weapons to destroy everything on the planet if there was no chance of winning.

###### A glimmer of hope

On July 1st, a ragtag fireteam of fighters, David O’Brien, Horatio Vincent, and Makayla Rogers, infiltrated the Inimic hive in Oakland to get information about the biology on the Inimics and spot a weak spot. Even though pure force from powerful weapons were already known to be effective at times, not many things were known to penetrate the strong armor of the Inimics. Horatio, being a skilled chemist, collected a sample from a dead Inimic, which was found to be vulnerable to high amounts of chlorine gas from their chemistry. However, they also studied the biology of the Inimic hive mind in the bay area, as they were the first to infiltrate their nearly-impenetrable defense. The three found that the stationed Inimics there were controlled by a single queen, who was intelligent on a human level and was responsible for laying eggs to create more Inimic soldiers. After the three recorded all the notes they needed, they completed their main task; to kill the queen there and destroy the hive. After a well-placed sniper round which killed the queen, the group detonated 15 tons of explosives they planted around the hive, destroying everything inside. This was one of the only victories taking place until that moment. Meanwhile, scientists in the National Canadian Computer Research Facility activated AS-1, the first combat robot which became sapient on accident. AS-1 was friendly and served with the Canadian Army and showed great combat skill from his code. Some AS-1s were copied onto other robot bodies, who took charge of entire platoons and squads.

###### A bolstered army

After the successful raid on the Bay Area Hive, the three members who infiltrated and destroyed the hive gave all of the information about how they destroyed the hive to the United Nations, who taught all military commanders and soldiers their tactic. Eventually, the armies around the globe began to score victory after victory, and eventually many hives were destroyed, adding no increase to the Inimic population. This kept on until three days later, when the Sol Queen got word of the tactic used by humans, and used her psychic abilities to totally change the Inimic tactic to be a more vicious, stronger opponent, while the Queen descended from the moon to the ruins of Jakarta, confident about their victory. This change was so powerful that the humans were pushed back right where they started from before the Hive-Hopping Campaign due to the change in tactics which heavily outmatched the humans. As the humans were pushed back towards extinction, they hoped for victory. That would come true in the most unexpected way.

###### Sagittarian Contact

The Sagittarian expeditionary fleet arrived in Sol on March 18th, 2027. After landing on Oakland, one of the few surviving cities, the humans were cautious about their presence as they might’ve came with a purpose to kill. However, the people were more than happy to hear that the Sagittarians were here to defend humanity with their help. Due to the Sagittarians’ understanding of the Inimic biology, many new tactics were created, and a final battle was planned to kill the near-immortal Sol Queen with help from Sagittarian, Synthetic, and human militaries. The Sagittarians also gave humanity advanced technology built for their biology with hopes of them utilizing those weapons to make their own ones. However, the Sagittarians were not able to fight the Inimics on their own due to their relative low numbers, 57,000 which wasn’t very effective as they were sent in an expeditionary fleet and FTL travel was not that effective at that time, so they could not request for massive reinforcements from Balyanka, their military’s HQ system.

###### The final battle: The Second Battle of Jakarta

The final battle planned by the three races took place in the ruins of Jakarta; where the Sol Queen and her hive lay from the first battle. This was their “capital” of theirs and destroying it would be a near-impossible but decisive task. On April 15th, 2027, these three military forces met in Borneo island, near Jakata. CIWS systems and other air defence systems were set up to counter the acidic weapons by the Inimic “cannons” and militaries were on high alert. A small section of Borneo Island was used as a forward operating base, known as Fort Pythagoras. For three days, they gathered their armies and defended their fort. Expecting the Inimics to attack first, the races, who made an alliance known as the Triple Alliance, kept watch until April 18th, where the plans were made and a massive attack on the Inimic hive was launched.
