hey guys, I have just realised that I have all my COD4 campaign done in the hardest mode except for 1 mission. Its the 1 where u have to run away after sniping Zakhaev. (love the way his arm goes off, but I would have prefered his head) I have managed to reach the extraction point but I cant survive long enough for the heli to reach us. Can u give me some tips on where to hide and what I should do. thx
