Today 2K games has confirmed that the upcoming XCOM shooter announced three years ago has "evolved". What this means is the game has changed a lot since we last saw it back in 2011 at E3.

"Firaxis' critically acclaimed turn-based strategy title, XCOM: Enemy Unknown, has reignited the classic franchise," 2K said, "and we feel that the time is right to deliver a new experience within the world of XCOM."

"2K's culture allows our studios the freedom to refine their visions, to explore new ideas, and to deliver the best possible experiences for players. Through this exploration, 2K Marin has refined their vision, and as a result the game has evolved into a high-stakes narrative experience imbued with core XCOM concepts," 2K added.

The XCOM shooter is under development by the same team who created Bioshock 2. No word yet on the release date.
