Halo 3: ODST Sells 2.5 Million Copies In Two Weeks

Only two weeks after, news has filtered out that Halo 3: ODST has managed to sell 2,500,000 units. This is a huge achievement for a game that many considered a smaller title in the franchise.

It's proving that it can definitely pull its weight with the big boys having already surpassed the sales of Halo Wars, although it still has some way to go before matching the sales of the three main installments the franchise has seen thus far.

Be sure to expect the sales of this Xbox 360 exclusive to rise in the coming weeks, and there is sure to be another surge around Christmas time.
