To sum it up, I'm talking about MW3. So today I'm going to inform you on tips for survival mode in "Spec Ops". So when you get up to wave 10, there is this thing called a juggernaut and is strong, so weak firearms "suck", go for explosives or LMGs. Waves 10, 15, 20, 25, 30, ect... those are some of the waves that have juggernauts. At about wave 23, helcopters will come in for most of the waves 23 though 25. this can prevent you from going outside, so I sugjest that you refill you ammo. Use the riot squad whatever you do use the riot squad. So I guess thats it.
