GameOn writes - "XCOM was one of the most surprising and controversial announcements of E3 2010. Many fans of the original series were up in arms about the reinvention of the franchise as a first-person shooter by 2K Marin. Indeed, the demo that we saw there a year ago had a lot more in common with the gameplay of Bioshock than UFO: Enemy Unknown, but it still seemed a promising and unusual title. So, it was something of a surprise when we discovered that a lot has been changed in 12 months. XCOM is now shaping up to be an unusual fusion of genres that promises to remain true to the themes of the early games."
