No. Quite honestly, it's annoying hearing W@W being called "Call of Duty 5". It just bugs me. If it's not in the original title, it should not be declared the fifth in a series. It is it's own seperate game from the series but still a part of the Call of Duty franchise.
it is not call of duty infinity ward has made it and independant game it doesnt have cod in its name just modern warfare 2
