This. Awesome missions there! Also I reckon that if you can do One Shot One Kill on Veteran without dying you've pretty much made it in the single player campaign. When I first tried to complete the game on veteran it was a hellish level for me, but when I made my second account and redid it I had some crazyluck and managed to pull it off first time without dying. :D I can usually get up the final point without dying, but then die like 10 times on the bit where you wait for the helicopter XD. Luckily ive already done it on vet. Yeah that bit's the only really hard part, but really good fun if you're a decent sniper. [hide=Spoiler?]Just run to the left of where you put Cpt. Mcmillan? (Can't remember name) down behind the tree near the radiation area. Plant claymores at the corner of the bumper cars closest to the tree to make enemies blow up. When the helicopter comes rush to the dude pick him up and carry him into helicopter quickly. EASYYYYYYYYYYYY >_>[/hide]
