DNF will be highly plot/story driven. You will always know where you are and what you are doing. You will know why you are doing it. You won't just be moving through a bunch of levels shooting stuff. Well, ok, you will be doing that, but you will have an in depth reason as to why. You will also meet colorful character's along the way that you will learn more of the story through. All in all DNF is a quantum leap over what we did in Duke 3D and that's part of what takes so long to make the game.
