Activision Blizzard's Call of Duty: Modern Warfare 3 video game racked up more than $400 million in sales on its first day in stores in the United States and the United Kingdom.

Activision said in a statement on Friday its biggest holiday title had sold 6.5 million units, which breaks last year's record of 5.6 million units, or $360 million in sales.

The version of the game released last year called Call of Duty: Black Ops went on to sell $1 billion in less than two months.
