Council of Nations concept art

XCOM is the titular anti-extraterrestrial organization at the heart of Firaxis Games' XCOM Enemy Unknown. The organization is formed in the beginning of the game by the Council of Nations, and must work to fight off aliens from around the world. If XCOM doesn't do a good enough job when it comes to eradicating the enemies, countries will retract their support from the project and leave you without important funding and items.
