A1: I wish I knew. I'm stuck at the Boss battle with the helicopter and just can't get through it. Why do they spoil good games my including impossible Boss battles?

A2: When you get to the helicopter part you continuously shoot the guy using the mini gun. When he dies the copter turns around then repeat the process. When the 2nd man using the mini dies the copter turns so the front is facing you. Just shoot the piolt in the head.

A3: Try to hid in cave,and wait for the halicopter to show without firing,now you can use snipe rifle and make a good aime the shoot,don't try to waste bulets,if you run out,sneak out of the cave then run towerd tthe box and get emmo..! Good luck 007

A4: Keep cover and switching cover whilst shooting the guy shooting at you presembly when he is reloading his weapon and then do exactly the same for the second guy. I know it is hard.

A5: I did it like this: take the bullits infront your starting position and go back to hide behind the stone you started from. Shoot the first guy in the helicopter (the light on his breast helps to find the target). After 7 to 8 hits he is done, the helicopter turns. Run to the second box of bullits and return to the cave. Shoot with sniper the second guy. Than, also with the sniper you can shoot the pilot with one shot in the head. Take your time to find out the movement of the helicopter. It repeats and you can prepare for clean shots.

A6: Take cover when against the helicopters and keep moving and taking cover at other rocks and keep reloading your gun and make sure that you have your gun in precise focus with R3.
