It became one of the best-selling titles of 2008, selling 3 million copies in the United States within the first two months of its release. It also marked the beginning of the Black Ops sub-series, as characters from World at War were carried over into its sequel, Call of Duty: Black Ops (2010).
Pushing the boundaries of what fans have come to expect from the record-setting entertainment franchise, Call of Duty: Black Ops II propels players into a near future, 21st Century Cold War, where technology and weapons have converged to create a new generation of warfare.
