Gabriel's Horn "When our Savior returns, He will punish the Evil ones for their wrong doings." Rocket Launcher : It looks like a beautiful, shiny white horn with gold on some of it. It works kind of like a grenade launcher that shoots rocket propelled grenades. 1st Perk: Tracking Exotic Perk: Rounds from this weapon will not kill enemies, but instead stick the rounds to enemies. When they damage an ally or you that rocket/grenade explodes within a large area. Hidden Perk: Holding down the trigger for a certain amount of time fires all rounds at once.
