if anyone is willing to get the non-case achievement add me mast3r sn3ak si my GT im doing from the wear all the cloths are least to kill however zombies you need to kill for the achievements
Who ever is in your room will not benefit from getting all the kills. Its best to do by yourself. Plus im sure nobody wants to stand on the sidelines or ride shotgun in the Hummer. Its 75,000 kills.
