Wallpapers HD of the XCOM Enemy Unknown Game

Firaxis, the creators of the Sid Meier's Civilization saga, have developed this turn-based strategy and tactical action videogame based on the mythical X-COM saga. The aliens have invaded the Earth and it is up to us to defend it using an army of soldiers and scientists that we will train in our own base of operations. XCOM: Enemy Unknown stands out for its extensive customization options and the concept of permanent death, which will leave us without those troops who fall on the battlefield.
