Plutonium

I've been playing for a while now but at some point i stopped after a couple of months i came back, now i don't remember the servers name. But i remember one of the servers which was for BO2 zombies Origins it had a cool system where you make any of the staffs, once you wanted to upgrade the server will tell you step by step on what to do it was really cool! but now i cant find it or maybe it got changed idk. But if anyone knows what I'm talking about I would appreciate the help!
