XCOM: Enemy Unknown is a turn-based tactical video game developed by Firaxis Games and published by 2K Games. The game is a "reimagined" remake of the 1994 cult classic strategy game UFO: Enemy Unknown (also known as X-COM: UFO Defense) and a reboot of MicroProse's 1990s X-COM series.

XCOM: Enemy Unknown was released in North America, Europe, and Australia for Microsoft Windows, PlayStation 3, and Xbox 360 in October 2012. An "Elite Edition", containing all previously released downloadable content, was released as a Mac OS X exclusive by Feral Interactive in April 2013. In June 2014, Feral released both XCOM: Enemy Unknown and its expansion pack XCOM: Enemy Within for Linux. A port for iOS was released in June 2013 and an Android conversion was released in May 2014. An expansion pack, titled XCOM: Enemy Within, was released in November 2013. A bundle containing both Enemy Unknown and Enemy Within was launched on the PlayStation Store for PlayStation Vita in March 2016 under the title XCOM: Enemy Unknown Plus.

Set in the near future during an alien invasion of Earth, the game puts the player in control of an elite multinational paramilitary organization called XCOM and is tasked with defending the Earth. The player commands troops in the field in a series of turn-based tactical missions; between missions, the player directs the research and development of new technologies from recovered alien technology and captured prisoners, expands XCOM's base of operations, manages XCOM's finances, and monitors and responds to alien activity.
