I personally don't like the AI of the operatives. Other thing is that they tend to push each other all to enter a room, when there is a room and you order a group to enter it, everybody wants to enter it at the same time. Multiplayer is the best thing of this game, but twice this game is not for it. I mean, one shoot one kills is not fun. It is no more a game.
Graphics are very good.
If you notice the style of the uniforms, the guns, the environment, the setting, the characters are beautifully done. Too much for an ordinary 3D card. But it all justifies for a great game. Sound is good, but I'd hope there would be more realism, like the voice of the operatives, like they are talking in a normal tone of voice. There would be more shouts in the orders, or in the conversations.
