There are two main types of weapons in Unturned. The first is a melee weapon. Melee weapons are simple. Once equipped, left clicking will execute a fast, weak attack. Right clicking with any melee weapon results in a longer, more damaging strike. This kind of attack costs the player stamina, and once you run out of stamina, you can no longer use this attack until enough stamina is recharged.
The second type of weapons are guns. Guns are relatively plentiful in Unturned, but ammunition can be scarce. Each gun uses certain kinds of ammo, so a shotgun won’t fire the same rounds as a pistol. By holding the T key, a gun can be inspected, showing the player what the gun has currently equipped and what ammo it can use. If a player has any customizable parts, this is also how guns can be customized. By pressing the V key, some guns may change their firing mode, from safety, to semi-auto, and even fully auto.
Regardless of what the player uses to fight zombies, it is recommended to aim for the head, as that does extra damage, even with melee weapons.
So Keep a sharp eye out for good Weapons to survive in the world of Unturned.
