REQUEST: Upgrade weapons

I think I've seen a script that allows to upgrade weapons:S But i'm not really sure.

Well, I want a script that allows to upgrade a weapon. I don't want to have new weapons for sale, but a single weapon that can be powered up instead.
Sorry, my english is bad:S
Is there some kind of scipt that can do that?

Thanks.

you could try something like this

Code: [Select]
