The Call of Duty clans in the UK will try their luck at qualifying for the ultimate Call of Duty XP event in LA to be held on September 2-3, 2011, on August 7 at the Sound Nightclub in London's Leicester Square.

The clans, or the team of 4 players, will take part in the 32-team, double-elimination qualifier. The UK event will be played using Call of Duty: Black Ops, and Call of Duty Elite will be live at the event to offer an analysis of the tournament as well as performance.

The winning clan will be awarded an all-expense paid trip to Call of Duty XP in Los Angeles and also the chance to play in the Call of Duty tournament sponsored by Xbox 360 with a prize of $1 million.

The Call Of Duty XP event in the US will be the first event offering a closer look to Call Of Duty: Modern Warfare 3's multiplayer mode. The registration for the UK event is open and players can go to the official site to register.
