Since DG Zombies is based of Cod Zombies, why not have a function that makes the current weapon you have alot stronger!
The Concept is simple to understand
You got a musket with mid damage, and a fast use rate
You just type in chat:
Then you would get a musket, now with
Good damage and a Faster use rate!
The Upgrade would be Percentage wise, (like 25 or 15%) and could be used whenever you want with the only thing restricting you being, is a 10k points fee and of course only being usable once per weapon you wanna upgrade
This could be very usefull on certain items like summons or items like the arkhails on certain maps, allowing you to use them somewhat longer and not needing to replace them
