Best of all, though, is the mission for which you're lent extra infantry from the Mexican army. See, one of our few criticisms of Advanced Warfighter is that your Ghost squad always operates as a three - you can't individually deploy your men, which will keep things moving quickly, certainly, but also cuts down your tactical options somewhat. The additional unit makes things much more interesting, giving you the ability to surround or lay traps for your enemies. Better yet, the mission level itself is brilliantly designed for the purpose, a ruined town filled with pale concrete shells which provides layers and layers of cover to move through, checking sight-lines and coordinating movements. It's tense, satisfying and really is excellently executed. 

There are some minor flaws worth pointing out. It's not as easy to surprise your opposition as the tutorial would have you believe, for instance, and they have a knack of spotting you and your boys just as you're settling into position. Similarly, enemy soldiers have an uncanny ability to predict when you're going to run out of breath while steady-aiming, popping out of cover to fire off a few rounds while you're sucking air and your sights are wobbly. And the fact that you're always crouching as you leave low cover gets to be very frustrating - at first having to tap L3 to stand when running to a new safe spot is no problem, but when you come up against a level that requires plenty of moving from cover to cover it gets to be a big pain.
