Call of Duty World at War is Call of Duty World at War and those people who use numbers are just making up a name or title because there used to be numbers before as in Call of Duty 4 Modern Warfare. Maybe it might be OK to refer to World at war as the fifth call of duty in the series, BUT IT NEVER WAS A COD 5
No but black ops is mint marbles
Right Analog Button for all Consoles if you are using the Default setting.
Call of Duty World at War(COD5,WAW) does not have a number, although it and Call of Duty World at War Final Fronts are the games released after Call of Duty 4 Modern Warfare. It started a pattern of not using numbers after the Call of Duty and the next game Call of Duty Modern Warfare 2 (COD6,MW2)and the just released Call of Duty Black Ops (COD7)also do not use numbers after the call of Duty. Although numbers have not been used for these games it has not stopped there unofficial renaming adding to the confusion.
