Well that was quick (and unsurprising). Just a week after Halo broke records and Call of Duty: Black Ops II has already gone and curb-stomped Halo 4’s impressive $220 million day one haul right in the face. In its first 24 hours, Black Ops II took all the monies, raking in half a billion in sales. It’s a multi-platform game, whereas Halo 4 is an Xbox exclusive, so really, both games have proven insanely successful. “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,” said Activision Blizzard CEO Bobby Kotick. Which of these games, if either, are you more interested in? Let us know which side you’re on after the break.
