The juggernaut's unleashed tonight.

British retailer GAME has weighed in on the importance of the release, declaring it the most pre-ordered game in the retailer's history.

"Call of Duty: Modern Warfare 3 is the most popular game for pre-orders that GAME and Gamestation have ever seen," company spokesperson Anne-Marie Mason told Eurogamer.

"Beating records set by last year's number one game, Call of Duty: Black Ops, Call of Duty: Modern Warfare 3 is now GAME Group's largest pre-order title in the company's history."

Call Of Duty's well known for breaking records — last year Call Of Duty: Black Ops became the fastest selling video game in history, shifting 1.4 million copies in a single day.

Whether or not Modern Warfare 3 can repeat the feat remains to be seen, but we certainly wouldn't bet against it.
