AlterIWnet hack

I need some help finding a hack that someone put on a server. I don't know if he made it himself, but just in case I'm gonna ask you guys what the mod is. This mod was that he could give us all killstreaks, and if you pressed n then you had this killstreak hack on for sunglasses, four-armed zombie mode, ect. He also had a message that said, "(username) has stationed turrets!" and turrets popped up. And another message also popped up saying, "(username) has help from the heavens!" or something like that, and a bunch of rockets came out of the fence I was near and exploded. What mod is this?!
