Last year, a listing of Take-Two and 2K Games' XCOM: Enemy Unknown appeared on a Korean video game rating site, showing a release of the game scheduled at an unknown date for the PlayStation Vita.

Today, XCOM: Enemy Unknown Plus appeared on the PlayStation Store for £15.99. Currently, the "Plus" seems mysterious, with no extra content or features announced. 2K Games didn't even announce that the game would be released until today!

You can purchase the game on the PlayStation Store here.
