A special request

Surely someone has payed a Co-Op server where there is a spawn then you pick up your weapons then you fight bad guys…
well you know how the weapons automatically resupply?
I want someone to make an entity that is pretty much an auto re spawning weapon(s) that you can pick up and everything.
If it is already out there, link it.
If you know positively for a fact it is impossible… then tell me. I dont want to request something you can only make in a map making program.
