A series of short stories based on the original 'Things XCOM Operatives Are No Longer Allowed to Do' list as well as a few other rules thrown in for good measure.

X-Com has always been a diverse organization. It has been in existence for a long time and there are secrets within secrets hidden from everyone. I started writing this back in 1999 but it fizzled. Here we go again. There will be spoilers from lots of old X-Com games as well as the newer ones and references to my works. This is a fanfiction, I own no rights to any X-Com title.

XCOM 2's events loom on the horizon of a Earth XCOM-less and boosting smarter Elders. Unluckily, someone else has taken notice of the intruders- stuffed animals, and they're not willing to let the aliens have the planet or the destruction of humanity that easily. Follows Pillow Central and co's attempts to inform and prevent, as well as some inner self discovery along the way.

Pretty much my Xcom playthrough but I make it a bit more dramatic.

A collection of excerpts and drabbles pertaining to SFTD.

A collection of documents, dossiers, and analysis on the various units, factions, organizations, cultures, history, events and leaders spanning the Ethereal Collective, ADVENT and XCOM. A supplementary companion collection to XCOM: The Advent Directive.

The Assault on the Temple ship was tough and unforgiving, leaving only two to make it to the very end. Once they destroyed the ship, the two were sent in a different world much like there own. One were the aliens and humans swapped places. [ this was adopted]

It wasn't a black hole. It was a wormhole. And now, the Volunteer of XCOM is stuck in an Alternate Universe where the Humans and Aliens swapped their roles and places. As said above, this is an AU. Attention: CANCELLED

The Elders rule over the Human and Viper races through the powerful Advent forces, which support their regime. It seems that the only way to achieve freedom is for the two races to fight together against their shared enemy. But, is such a union even possible, when there is so much bloodshed between them? Can anyone unite their races, and overcome the hatred both feel for the other?

Meet the Grunt. Recruited to save the world; actually not too good at it. But he pulls through anyway. Within the First Star universe.

Field Commander "Eagle-Eye" left XCOM many years ago, frustrated with many problems inside it. He joined the resistance and led his one man army against the aliens, but now that the situation has only grown worse, he may have to return to XCOM.

Classic AU set in X-COM Apocalypse. Disclaimer: Classic games were developed by Mythos Games. Rewrite of my previous attempt. Please R&R to help the development of this story. Enjoy! :)

It's been 20 years since mankind surrendered to an Alien Invasion and the world is under a new regime. But not all accept their new overlords. After rescuing the Commander, the real war has begun.

XCOM attempts to recruit survivors of a retaliatory attack from ADVENT in preparation for the weeks to come. Among them is a young engineer named Erica who will become one of XCOM's first martyrs.

The Alien threat has arrived, and nobody is safe. Can Commander Grant save the world, or is it all for nothing?

This story is being rewritten in order to do it better a second time.

Not quite sure what to do with each class in XCOM? Here's a helpful song for you!

Earth is fallen. Aliens rule the planet. The shattered remains of XCOM must united with other resistance forces and take back the planet. Commander Frost has his work cut out for him as the aliens won't go quietly. A WOTC novelization with plenty of original content and characters.

Sequel to 'Found Redemption'. Richard Tygan doesn't quite feel at home at the Avenger. However, things are about to change...

Awaking to another utopian morning in the settlement of New Luxembourg Alicia Taylor prepares to face the coming day and all it will bring.

Probes rain from the sky and unseen beings stalk the streets. A fleet of hostile spacecraft orbit the sun, and there seems no way of stopping the alien menace, only of delaying the inevitable. Funding X-Com is the world's final gambit, but few truly expect it to succeed. (Loosely based on Long War. Follows several characters, both canon and OC. Be warned: some die.)

When XCOM removed the biochip of a living Viper, they unintentionally gave her something else: Freedom. No longer a brainwashed servant of the Elders, Natasatch asked to join XCOM, much to the project's surprise. However, the prospect of integrating an alien into such an anti-alien organization may just be XCOM's most ambitious experiment yet.

A collection of documents detailing ADVENT notes on developing technology in the ongoing fight against the aliens. Companion series to Xabiar's "XCOM Files".

The Vipers are free from ADVENT and the false gods. Free to choose, to live, to stand for what is right. One of them, T'vara Ty'Shok is about to face a fight for her own life and protecting her family against a dreadful threat from the ashes of ADVENT. A civil war breaks out between two sides: The peacekeeping Viper Republic, and the loyalist Valorian Regime.

It became very clear that this was not your everyday Sergeant who was addressing me. No, this was the voice of complete authority. Pure and utter respect was demanded from that voice, and nothing less would do. A small shiver of fear and admiration ran through my body. Not only because of what they meant, but because of who they were delivered by. "Drew Crawford, Squad Lockdown."
