Black Ops is UK's best-selling game ever - Report

Activision's Call of Duty: Black Ops was crowned the United States' best-selling game of all time in March, when it was revealed that the game had sold 13.7 million units. Now, the blockbuster shooter has become another region's biggest game of all time.

According to Gfk ChartTrack (via CVG), since Call of Duty: Black Ops arrived in the United Kingdom in November, it has sold 3,722,411 total units as of June 25. That figure makes the Cold War-era shooter the UK's best-selling game of all time, ahead of previous top-spot holder Call of Duty: Modern Warfare 2, which has sold 3,702,41 in the region.

The last official United States sales tally for Call of Duty: Black Ops comes from February, when the game reached sales of 13.7 million units. Further, the shooter has likely sold many more copies than that, as it has graced the NPD's top 10 software list every month since.

As for how many total units Black Ops has sold worldwide since its November debut, Activision has not said. However, one analyst pegged the title as selling 20 million units. Combining the official US tally of 13.7 with the UK's 3.7 brings Black Ops' total haul to 17.4 million, a figure quite close to 20 million.

And Black Ops continues to grow. Today, Activision released the $15 Annihilation map pack for the shooter on Xbox Live. The content packs in four new multiplayer maps and one fresh zombie level. It is expected to arrive on the PC and PlayStation 3 at a later date.
