Till now from what i have experienced(I am still in act 1). You have an option of watching the mission briefing separately.Cutscenes so far i have seen were just amazing.You can say this is a different type of game.Cutscenes are quite natural and artistic they successfully gives the depth to the story.There are different cutscenes for different difficulties wich gets played after you select the difficulty and they are really fun to watch. But as i have mentioned the game seems a bit slow,or maybe i need to master the controls more.
