Activision is claiming that it has delivered the biggest game launch of the year with Call of Duty: Black Ops 2, estimating that the latest Treyarch game made $500 million in sales on day one.Sales data was consolidated via sales monitor GFK Chart-Track along with "retail customer sell-through information" and "internal company estimates".Activision's newest blockbuster could, if its estimates are accurate, be poised for a new entertainment record with Black Ops 2. However, the publisher has yet to confirm this.Modern Warfare 3 grossed more than $775 million globally in its first five days of availability, exceeding the $650 million record set by the 2010 Black Ops across five days.Activision chief executive Bobby Kotick claimed that life-to-date sales for the Call of Duty franchise have exceeded Star Wars.He added: "With first day sales of over half a billion dollars worldwide, we believe Call of Duty is the biggest entertainment launch of the year for the fourth year in a row".Black Ops 2 launched across the west on November 13th with an estimated 16,000 midnight openings across retail."Call of Duty has become more than a product people buy, it's a brand people buy into," said publishing boss Eric Hirshberg.
