Basically you would have to get kills in the different tiers with a specific weapon.
Ex
You have to get 100 kills with each tier for a gun of your choicing for a super kuro armpit gun
You would have to get 500 kills with each tier to unlock a super coolio ball gun
Also could make it just a gun type in General like all smgs, all smg ammo variants, all 9mm variants, all assualt rifle varrients .
This way people wouldn't be using super sweaty trihard tobias power creeper guns.
