Activision has announced the creation of Call of Duty XP 2011, a convention designed to celebrate the game’s community. Set to take place on a 12-acre compound in Los Angeles September 2-3, the event will host a reveal of Call of Duty: Modern Warfare 3‘s multiplayer mode. The company anticipates that 6,000 attendees will be able to get their hands on the game’s cooperative and competitive multiplayer modes, and check out the fully functioning Call of Duty Elite service over the course of the convention. There will also be a $1 million Call of Duty tournament, with players able to qualify on site or by competing in regional Black Ops qualifiers, paintball competitions on a life-sized multiplayer map, live entertainment, and developer panels.

Tickets go on sale July 19 and will cost $150 each. All of the money from ticket sales will go to benefit the Call of Duty Endowment, a nonprofit group founded by Activision in 2009 to help soldiers transition to civilian life with job placement and training programs.
