how to make the gun terraria

Answer 1

You actually cant craft a gun in Terraria. However the first Firearm you aquire is the most common. The musket. The musket is obtained from breaking a shadow orb in   the corrupt chasms. Upon breaking the ORB you are given some Musket Balls to get yous started. Once you have had the Musket (and a place for a NPC) The arms dealer will move in. From there you can purchase the handgun(pirate-sque) and the Mini-shark(machine gun) along with some ammo. Once you buy the Minishark you can upgrade it to fire fallen Stars...You can also upgrade the handgun to the Pistol... Thanks and Have a Great time on terraria!
