Gears of War has gone triple platinum, reaching the 3 million-units-sold milestone in just 10 weeks on store shelves, ending 2006 as the top-selling game among all platforms during the month of December.

Expanding upon its reign as the fastest-selling title of 2006 and the fastest-selling original exclusive Xbox game of all time, Gears of War has recently seen new multiplayer maps, Raven Down and Old Bones, released online. Since the downloadable content’s release via Xbox Live Marketplace less than two weeks ago, the new maps have garnered 750,000 downloads. There have been more than 1.5 million total downloads of all Gears of War content currently available via Xbox Live, including the maps, themes and video walkthrough.

The Gears of War: Mad World cinematic trailer was featured in Advertising Age’s Book of Tens as one of the top creative concepts of 2006. With more than 2.4 million views of the trailer online, the campaign has inspired not a number of parody videos currently circulating around the Internet.
