Damn the second wave on the ferris wheel is hard!
I can snipe the crews of two choppers (the soilders)...then when they land I get screwed by dogs and soldiers who just pop out of no where. I run out of sniper ammo and I have no C4/claymores.
if you place the claymores correctly, you should wipe out at least the first 2 waves with little no no ammo use, just the claymores.
sit on the decking of the ferris whell, you get the best view and also keep the ak as your second gun, so that if someone comes up close to you, it wont be hard to switch around.
