Halo 3: ODST Sells 2.5 Million in Two Weeks

Any doubts that Bungie's Halo 3: ODST would be a success were quelled with word that the game has sold 2.5 million copies in its first two weeks.

As reported by USA Today, overall sales amount to $125 million in revenue so far. nope "That's pretty good for a game that most called an 'expansion pack,'" said Wedbush analyst Michael Pachter.

The original Halo 3 did $170 million in sales on its first day of business, eventually topping $300 million in its first week. But Halo 3 was produced over a span of several years; by comparison, production on ODST only lasted a brief 14 months, representing a much smaller investment.
