Call of Duty: Black Ops has been torrented more than four million times, easily enough to make it the most pirated game of 2010 ahead of runners up Battlefield: Bad Company 2 and Mafia 2.
TorrentFreak made the announcement, gathering the figures from public BitTorrent trackers to create a list of the top five most pirated PC games of the year. The list is as follows.
Call of Duty: Black Ops takes the dubious honour of following last year's most torrented game, Call of Duty: Modern Warfare 2. TorrentFreak report that piracy numbers are up slightly from last year's front runners. The Call of Duty: Black Ops piracy figures are still dwarfed by the game's success at retail, with Activision having announced that they've already made one billion dollars from worldwide sales.
