You might need to fill that flask, er, "canteen" with more than just Kool-Aid if you plan to make it through the first few weeks of Call of Duty 5Call of Duty: World At War boot camp. You see, you bought the "Limited Collector's Edition," which includes, in addition to a storage tin (guaranteed to fit other Treyarch games!) and the aforementioned sipping container, the infamous "Day One Advantage." As if spotting the guy with the ridiculously over-powered machine gun won't be easy enough, you'll also be pinned with a "uniquely colored clan tag" identifying your "VIP-status" in online multiplayer. In other words: Everybody kill that guy! Yeah, you.
