FleshEatingZipper says: "Survival mode is one the new additions to Call of Duty: Modern Warfare 3 and one of my favorites. Think of it as Zombies from Call of Duty: Black Ops but without zombies and having to barricade back up. It’s just waves of enemies coming at you and it’s not just light troops; you have dogs, Juggernauts, suicide bombers, suicide bomber dogs, claymore experts and helicopters. Sometimes it’s all of them in the same wave, sounds interesting doesn’t it? I’ve played Survival mode more than anything else in the game and have learned the best ways to survive. "
