At first, I found this game a shock. They had change the controls a little, the guns and other weapons where different and the first mission was really dark. I am only into the thrid mission and already I find it is, in my opinion, the best SC game yet. They have added a percentage system into the game, which has made me replay each mission so far several times to get 100%. Good graphics and a great challenge. A nice change from hardout shooters.
