I just bought MW3 after my old one broke. And I looked in mqy vault and I have all these mods. Knockback is my favorite one, so ill be hosting a public knockback lobby. If you wanna invite anyone go ahead. Message me for an invite. GT: Exortation. When you get in the knockback class is the KSG. Someone stands on something and you crouch below them and shoot them in the head and they go flying. The closer you are to the person the better.
