#10 XCOM: Enemy Unknown

XCOM: Enemy Unknown is a turn-based tactical role-playing 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. It has versions for Microsoft Windows, PlayStation 3 and Xbox 360.

Set in the near future during an alien invasion of Earth, XCOM: Enemy Unknown puts the player in control of elite multinational paramilitary organization called XCOM and 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.
