Plutonium

Hi there,
Just wondered if there’s anyway of unlocking camos without going to master prestige (unlockall) ?
I tried using unlockall on the commands, then trying to set my rank levelxp to 1 but results in an error when reloading in to BO2.

Hi all,
set up my username as '_GT' and everything went through fine, although after being on a server for a second, I am kicked as my name is not allowed on the server.
Is it possible to change my username? I can't find how to access my plutonium account.
Many thanks.
#FIXED - I simply clicked on my name after posting. Sorry for bothering!
