SC CT has a great combination of tactical shooting, strategy, and adventure mushed up into a ball of awesome-ness!
Each room in the game has different size, different amounts of mercs, and special stuff, like automatic turrets! FUN!! There are great things in this game that you can only expirience if you're smart, like shielding yourself from guys with heat-vision in steam, or something like that. This game has some really intense action sequences, like when you have to disarm bombs in a sauna room, and while you're busy disarming a bomb, your enemy walk through the steam and into visibility from out of nowhere, and fills Sam Fisher's mind with paranoid thoughts. I didn't word that right. He basically walks through steam, says something like"Oh Sam, you're just a puppet being dangled by the fingers of Lambert" or something. It was creepy! It doesn't sound creepy when I write it, but if you saw it... Whoa!
So, the graphics are awesome, but the one problem I had was the blocky and obviously pixelated shadows of trees. I think that's my only complaint of the game...WOW!
