One aspect of this that drove some people up the wall was the lack of an in-game save system, and this is set to continue with Raven Shield. "It was something that we looked into", Mike confirmed, "but once you get in-game saves in, it really changes the pace of the game, because the pressure's off. With in-game saves you would clear a room, save it, clear a room, save it... That's a different gameplay. With Raven Shield you can do everything right except for one room, and you can lose. So the pressure and the tension is there. When you take the tension out of Rainbow Six you really lose the feeling of it."
