Great game that really capture the feel of the old 1994 game so i recommended this to anyone that liked the old ones. There is also a expansion called XCOM: Enemy Within. It adds some new elements such as the MEC trooper and a new human enemy faction to the game. The optimal mix for me was two MECís, two genetic soldiers and two human soldiers on each mission. Play it. Play it Now.
Here I write what I think about the games I have played. The score is shown as a smiley before the title of the game.
Note about Movies: None of the Youtube movies that i link to are made by me and i include them only to give you a chance to see what the game looks like. Only the text and the smiley score act as my review of the game .
