from no0b to veteran

These are a easy few ways to go from a no0b to veteran. One way is if you are new to the Call of Duty series and you are not very good at the default maps, you could buy the map packs and get a wider range of map selections. Also you could look up ways to make a class if you aren't very good at creating your own class, or if you just want to see other peoples views of the oppertunites that "create a class" has.
