I have had all of the Black Ops dlc from day of release but I've never managed to play the zombie mode in any serious way.:-(
So if you're up for getting some achievements and for having some fun over XBL then please feel free to send me a pm or to add me your friends list; it would be better for anyone from the U.K. or Ireland (for obvious reasons) but I'm not too fussy!:-)
I'm a friendly guy and an average gamer so don't worry if you've not too experienced with this mode.
