The first boot of a new Call of Duty game is a crossroads with no right choice: do I jump into the big, flashy campaign headlining the game, or step first unto the virgin grasses of multiplayer, where no meta has yet taken root?

Activision is making that choice a bit easier for those who buy Call of Duty: Modern Warfare 2 early. In a first for the series, those who pre-order will have early access to the Modern Warfare 2 campaign (opens in new tab) on October 20, a full week before the game officially launches on October 28.
