Hello, this idea has been in my head for two whole years now, and this is a time for me to try to actually turn it into an actual one. A few notes: in this universe, XCOM 2 and Chimera Squad didn't happen, and we are pretending that it's Long War rather than vanilla. Also, I know that actual military dress codes would laugh out a lot of xcom characters, but consider: I am lacking in fucks to give.

I do not claim possession of either GATE or the XCOM franchise, these belong to their respective owners and the only thing that I own are any OCs, which would most likely be XCOM squaddies.


Either we are alone in the universe, or we aren't

In 2015, humans learned the answer to that question under a hail of plasma and metal. A war that they were bound to lose, they had limited numbers, they had technological inferiority, and they were divided.

Had it not been for the forces of the Extraterrestial Combat Unit, or X-Com, under the guidance of the Commander, Sydney Thorn, she led the soldiers of X-Com and fought a hard war. That war was fought for three slow and torturous years, she led the global defence against the extraterrestrial menace, reverse engineering technology, as the world hung on a knife's edge. New technologies were invented and rendered obsolete in those hard years, with even what it was to be human being called into question.

Many were lost, either dead or missing presumed dead, with even more lost during the many alien bombing runs. Had it not been for the sacrifice of the Volunteer, Major Alex Parker, the most powerful psionic that had ever been seen, the cost would've been even higher, the price would've been Earth itself.

But the tens of thousands confirmed dead and the hundreds of thousands that have gone missing are considered a pittance in comparison, not that it helps with mourning.

By the year 2019, Earth is healing somewhat, bonds between the nations were tested during the Etheral War, and they only hardened to steel as a result. While many are not close to forming a one-world government, the UN has a lot more power and weight to throw around.

Despite the defeat of the extraterrestrial menace, XCOM is still well funded, though expansion and the war did lead to the organisation effectively being divided into five organisations. One for Europe, one for Africa, one for Asia (Oceania was included under this distinction) and two for the Americas. This was a division that was made official from one that existed during the war, with various theatres of war operating with their own soldiers in order to maximise coverage.

During these years, the technology fabricated and reverse-engineered has been put forward to healing the world. MELD based prosthesis were made available for the general public after the war, though at significant cost due to obvious reasons. Gene modding techniques are being investigated for medicinal purposes, though many do suspect that a good idea would be investigating how to reproduce MELD.

Similarly, Elerium based technology is also being investigated for potential civilian uses,, though XCOM is mostly keeping the more destructive technology for their own purposes. With most pulse, plasma and laser weapons often left gathering dust, in the hopes that they won't have to be used again.

Though don't take their want to not use Elerium weapons as a sign of weakness or laxness. XCOM still remembers what they are, they are vigilant, they are necessary. They are Earth's first and last line of defence, whatever they may be defending against.

And as of late, a strange object has started to appear in Tokyo, almost classical in design.
