Between enjoying some healthy competition with Halo 3 for fastest selling title and most played online game, Call of Duty 4 can now add another kudos to its throne: fastest selling downloadable content. It's only been 9 days since the Variety Pack was released for the 360 version and in that time, it has sold a staggering one million units online. One million unit?!? That's absolutely massive when you consider al those people clamouring to find online rooms to have Team Deathmatches in on the new maps. Also between the 4th of April and the 12th of April, gamers logged an amazing 30 million sessions altogether adding up to 32 million hours spent online. All that's left to see is if the success contunues once the maps are released for the PS3 version. Well from our end I can say that we're desperately waiting for the maps and can't wait any longer!
