Description

Released in 1993, the original X-COM is widely regarded as one of the best games ever made and has now been re-imagined by the strategy experts at Firaxis Games. X-COM: Enemy Unknown will expand on that legacy with an entirely new invasion story, enemies and technologies to fight aliens and defend Earth. Players 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.
