One solid proof that Halo 3 is flying off the shelves is the massive activity on Xbox Live. More accurately, 1.2 million gamers (unique gamers, that is) have logged on the multiplayer servers, according to none other than Bungie. In addition, Bungie’s data shows that over 4.5 million online matches have been played and over 400 million enemies have been killed in the campaign. Expect the number to increase sharply over the upcoming weekend, and throughout the entire holiday season.
