Shoot down the armed men by launching an attack in their own territory. Your mission is to shoot down as many armed bad guys as you can with your trusty Desert Eagle, M4 and Sniper Rifle. Get a kill per shot to receive a monster kill bonus.
Snipe the snipers before they snipe you. Once you start shooting, the sniper timer will count down fast so you may want to try and remember their positions if you can. Watch out for the sneaky soldiers that move in and out of cover.
