Weapon Slot

Weapons Slots (Item Slots, or just Slots) are places that you carry your weapons.

Overview
Each player has 1 default slot for each weapon category, including 1 Primary, 1, Secondary, ONLY 1 Melee, and 1 Grenade/Support Item.

Using different backpacks, players can carry (and thus bring with them) extra items of different categories (like, say more Machine Guns or Grenades), excluding another melee weapon. You cannot bring another melee weapon with you no matter WHAT the situation.

The number of weapon slots you have depend on the "size" of your backpack. For example, an Advanced-level backpack (2-slot) can only carry two additional items, and a Utility-level (3-slot) can carry up to three.

Three additional slots are currently the limit for any backpack (though the original limit used to be 2), and it is subject to change at any time.

There is also a SECRET "6th" slot, which players may use for special items. These may include other weapons or miscellaneous items (like the Bomb or Dynamite, and in the case of Specialists, their Specialist weapon.
