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 and
its resources in a battle against the terrifying alien invasion.
XCOM: Enemy Unknown
is a reimagining of X-COM,
the classic strategy game from 1993, and developed by the award-winning
creators of Civilization. You will control the fate of the human
race by creating and managing a fully operational base, researching
alien technologies, planning combat missions, and controlling soldier
movement in battle.
