Call of Duty Online -the free-to-play shooter that draws together maps from Call of Duty 4 and Call of Duty: Modern Warfare 2 – is only available in China, but Activision says it could launch it elsewhere. Activision’s CEO of publishing unit was quizzed about the possibility of Call of Duty Online launching in other markets. “I think we look at the Call of Duty Online game in China on its own merit as a great opportunity”, Hirshberg explained, “That’s not to say that we won’t gain learnings about how it works in the micro-transaction-based format for the game. And there are a few other regions where that would be very relevant. So — but we certainly are not ready to announce any plans in that regard.” Check out the Call of Duty Online reveal trailer here:
