make an upgrades shop where you can upgrade your inventory or weapons

Example:

tertiary weapon slot where you can equip melee weapons only and the secondary weapon slot will give all its melee weapons to the tertiary weapon slot

You need to be rank 16 to buy this upgrade you cant keep it you need to buy it again like items the cost should be 210 dollars
