Other than the single player campaign, isn't all Call of Duty online? Well, yes. But in China, it's Call of Duty Online. Announced today, the game is published by Chinese gaming giant Tencent. Activision first mentioned the free-to-play, microtransaction-based game back in February 2011.
Late last month, Activision snatched up a slew of Call of Duty related web addresses—17 in total. The websites are probably protecting the Call of Duty online presence in China from internet bad guys.
