Really looking forward to this, because it actually looks realistic. For example, the soldier is shot, possibly killed, and you actually run over to him, check his safety, and pull him out of danger.
I was also impressed when, during the sniper scene, the soldiers actually covered each other, and made swift transitions through cover (even if it was scripted, it was still awesome)
Hopefully you wont end up running into a room with 2 shotguns, blowing the forget out of everything, like a kid with ADHD. (looking at you, Modern Warfare 2)
I seriously only enjoyed that very first level in Modern Warfare 2, when your in Afghanistan, firing grenades across that concrete dam, and exchanging fire at a good distance. That was cool, because you weren't standing next to the person, stabbing them in the throat with two knives, or throwing magical sticky grenades at people.
