Sales of Microsoft's Xbox 360 console have more than doubled since Halo 3's release on 25 September, the company has announced.
"Halo is truly a cultural phenomenon, and the launch of Halo 3 is an important milestone for Xbox 360 and for video games as entertainment and as an art form," said Microsoft founder Bill Gates. Halo 3 has also attracted almost three million players to Xbox Live.
"Halo 3 embodies our vision for the future of entertainment, where some of the world's greatest creative minds will deliver a new generation of interactive storytelling."
Last week, Halo 3 topped Spiderman 3 to become the highest earning entertainment launch in history with more than $170m in single day receipts.
