XCOM: Enemy Unknown is a turn-based tactical role-playing game developed by Firaxis Games. XCOM: Unknown is a remake of the 1994 game UFO: Enemy Unknown. In Enemy Unknown you play as the commander of XCOM and as the commander it is your mission to take out the alien forces you come across in the game. XCOM: Enemy Unknown released on the PS3 on October 9, 2012 in North America and October 12, 2012 in Europe.
XCOM: Enemy Within is a brand new expansion for the game XCOM: Enemy Unknown that was revealed at Gamescom last month by 2K Games. Enemy Within adds new maps, weapons and bosses for you to fight in the game. To show you more about Enemy Within, 2K Games has released a new gameplay video of the expansion in action. In the video, players get a walkthrough from one of games designers on some of the new maps and weapons in the game. Since XCOM: Enemy Within is so big it won't be releasing on the PS3 digitally, but will be releasing by retail via the Commander Edition, which is what it is called. It will be priced at $40. XCOM: Enemy Within will be releasing on November 12, 2013.
