Sonic Colours approaching two million.
SEGA has revealed it shipped 820,000 copies of Platinum Games' Vanquish worldwide in the period up until December 31, 2010.
The action title launched worldwide on Xbox 360 and PS3 towards the end of October 2010.
Other titles released in the October-December quarter included Sonic Colours (1.85 million copies) and Football Manager 2011 (690,000 copies).
"In the overseas markets, sales of the new titles remained slow as affected by the adverse market condition, although sales remained solid in the Japanese market," said SEGA.
Vanquish looks set to surpass one million sales in its life-time, but has tracked behind the sales of Platinum Games' previous multi-platform action title Bayonetta. The studio has so far been focusing on pumping out new IP, but there does at least appear to be a solid base from which to build sequels.
