If you are in survival and can't beat a juggernaut I got my own cheats to smash him. 1. Get 2 player or 1 but 2 is easyer to kill the big guy 2.both players get a riot shield squad 3.both players get sentry guns does not matter wich 1 4.get a M6OE4 and both players shoot the juggernauts head 5. If your squads get killed just buy more 6.doing all this I got up to wave 25
Go to the back of the map stand on the wall with a riot shield out and throwing knife get your mate to stand the other side of the wall with his gun out. Stand behind the tree and whack with the riot shield and get your throwing knife out
First get a buddy and first go to mw3modz.com get the knock mod then go in dome building and go near back entrance lay down and you look at your buddy he will have a gold shotgun he shoots you in the head but you don't die you fly in the sky when you get up place your tacticle insertion then come down get your buddy up then HOLD your grenade do not throw it you will die and spawn back jump down in the grass near the ladder then lay down shoot your buddy over fenc then run around dome come to the cave and jump in map get your other buddy out of map then if you picked up your tack then put it out of map before doing this so then hold your grenade and bam your both out of map and you can run anywhere hope you enjoy!!
First go to dome on multiplayer run to the building with the dome on top look on the sides of the building"both sides" when you find this blue thing on the wall and jump on it "it takes a couple tries" after that look to your right then jump on the pipes by the window jump on the window and look up jump in the little space and go inside the dome run to the spot with the fence on both sides go in it and your partly out of the map
