Sid Meier's Civilization V + XCOM: Enemy Unknown

Sid Meier's Civilization V is the fifth instalment of the greatly popular series of turn-based strategy games. The developer, Firaxis Games studio, remained loyal to the basic rules of the saga. The players' goal is to direct their civilizations through consecutive epochs.

The interface received much tuning-up and can now be set as transparent, minimalistic and user-friendly. Not all options and functions are available straight off the bat, but even the hidden ones can be accessed with only one mouse click. Notifications are displayed with an icon, which eliminates the need to go through multiple text messages. All the changes have been implemented to facilitate user control. First time in the series' history, a hexagon net has been introduced to the world map. Due to this, additional strategic options open up during war. The modification also allows for a more intuitive exploration of the territory and a better development of the player's superpower.

XCOM: Enemy Unknown will place you in control of a secret paramilitary organization called XCOM. As the XCOM commander, you will defend against a terrifying global alien invasion by managing resources, advancing technologies, and overseeing combat strategies and individual unit tactics. 

The original XCOM is widely regarded as one of the best games ever made and has now been re-imagined by the strategy experts at Firaxis Games. XCOM: Enemy Unknown will expand on that legacy with an entirely new invasion story, enemies and technologies to fight aliens and defend Earth. 

You will control the fate of the human race through researching alien technologies, creating and managing a fully operational base, planning combat missions and controlling soldier movement in battle.
