2 k Games has released the official cover : XCOM Enemy Unknown along with a couple of new movies and screen devoted to the game. In the game the missions and the soil will be generated randomly every time. Developers claim that, as well, will never happen to replay a mission in the same manner for the second time. Exception is made only for a couple of missions particularly important for history and featuring in-game footage. New details on the title and gameplay demonstrations are expected for E3.
