hide against the wall till it stops firing then run out and shoot it. as soon as you finish off the swat run back and hide agaisnt the wall so it cant shoot you. then run back out and shoot it. Keep ammo for the swat. If you are playing ghost wait till you are chased by the twins. Noabi is the worst driver ever!!!!! I beat it yesterday with ghost. 5 hours 40 min or so total.
