Xbox 360 Hits 17.7M Units Sold, Halo 3 Sells Over 8.1M, Mass Effect Sales Top 1.6M

The Xbox 360 has sold in excess of 17.7 million units worldwide, Microsoft revealed today in a statement that included several other sales figures.

The company also announced that Bungie's Xbox 360 exclusive Halo 3 has sold over 8.1 million copies since September 25, 2007, with BioWare's fellow Xbox 360 exclusive Mass Effect moving more than 1.6 million units after its November 20 release.

The figures follow proclamations made by Microsoft VP of corporate marketing Jeff Bell last December, in which he claimed that Halo 3 had sold in excess of 5 million units and Mass Effect sales totaled over 1 million copies.

"When we look back at 2007, we'll say this was the best holiday lineup in video game history," Bell stated at the time.
