Black Ops DLC sales up 40% over MW2

Next to surpassing sold boxed copies, Call of Duty: Black Ops has out-done Modern Warfare 2 in the DLC arena as well.

Sales generated from the game’s first three map packs — First Strike, Escalation, Annihilation — are up 40% when compared to its 2009 predecessor, Activision revealed on its second quarter 2011 earnings call yesterday afternoon. In total, the three packs sold 14 million units.

The fourth map pack has just been announced as well; the all-zombie Rezurrection will be out later this month.
