Shack News: "XCOM has been delayed so often and has changed so drastically that it may be hard to keep track of what the game is. Is it still a FPS? (No.) Is it related to last year's XCOM game? (Not really.) Is it still called XCOM? (No, it's now called The Bureau: XCOM Declassified.)
Don't worry if you haven't been able to keep track of The Bureau's many changes. XCOM as it is today can be best summed up as this: Mass Effect, set in the 60s."
