Well, I honestly can't compare the demo to the full version. When I was playing the demo, it was on a different box. Since then, I built the new machine listed in my sig. I can say this, the gameplay I have experienced has been awesome. The fights are really dynamic, the AI is actually a worthy opponent. At one point last night, I was peeking around a corner unloading on two guys hiding behind boxes and I hear over their radio "flank him!!" Out of the corner my screen I saw two more guys running down an adjacent hallway to get behind me. In the meantime, i was still unloading on them and they were just reaching over the boxes with their arms and shooting blindly, dirka style.
