Call of Duty: Modern Warfare 2 has set several records this year, including the most units sold in a single month (over 6 million in November alone). But according to TorrentFreak, a site that covers the world of torrent downloads, the game was also the most pirated title of 2009.

According to the site, Modern Warfare 2's PC version was downloaded on torrent sites a whopping 4.1 million times, which is more than twice as many downloads as 2008's most-pirated game, Spore. The Xbox 360 version of Modern Warfare 2 was downloaded 970,000 times.

Those numbers are all the more impressive when one considers that the game was downloaded over a period of just two months.
