From the award-winning creators of Civilization comes an action-strategy game about humanity's last stand. Threatened by an unknown enemy, the Earth's governments unite to form a secret paramilitary organization, known as XCOM, to combat this extraterrestrial attack. As the commander of XCOM, you control the global defense team in a battle against a terrifying alien invasion by creating and managing a fully operational base, researching alien technologies, planning combat missions, and controlling soldier movement in battle.
