Surprise -Surprise, Microsoft’s exclusive shooter Gears of War 2, sold incredibly well. Epic’s latest hit sold about 2.1 million copies of the critically acclaimed game and puts it in a great place to be one of the biggest titles on the system.

In the United States, Gears sold approximately 1.4 million on Friday while selling another 700,000 units in other counties. However, compared to Halo 3’s launch, Gears of War 2 would be about two-thirds short of Bungie’s first-person-shooter. However, when you compare some factors of Halo 3, what Gears did is remarkable.

Not only is Halo 3 the third game in the series — it’s Microsoft’s flagship title. Just remember the amount of money Microsoft spent for the marketing of the game — nearing the $40 million mark. Gears of War 2 didn’t nearly have the push that Halo had, so seeing what Gears did — is even more amazing.
