Another year, another November where Activision gets to tout its success with the Call of Duty franchise. This time around, the game company has announced that Call of Duty: Black Ops 2 has generated $500 million on launch day, becoming the company’s biggest opening yet. Call of Duty: Modern Warfare 3 hit $400 million in sales on launch day last year. As expected, Activision claims that the game’s success is due to its unique gameplay and new takes on a popular gaming genre. And as expected, the millions around the globe that have flocked to game stores have helped the game publisher celebrate.
