Total Call of Duty immersion is coming to a secure 12-acre compound in the urban confines of Los Angeles on Labor Day weekend, where more than 6,000 fans will be the first to witness the world premiere of Call of Duty: Modern Warfare 3 multiplayer. Attendees will be among the first to have the opportunity to get hands-on time with multiplayer and the new Spec Ops survival co-op mode. Also on display for the first time will be the full feature functionality of Call of Duty Elite, the innovative new online service, built from the ground-up to support Call of Duty: Modern Warfare 3.

Activision has tapped "green-collar" punk revelers Dropkick Murphys to perform opening night at 8pm, Sept. 2nd. The Dropkick Murphys--known for their complex distillation of classic punk rock, Celtic folk and American rock 'n' roll will deliver a knockout live performance.

"With an unbeatable lineup of real-world and in-game experiences, Call of Duty XP was already poised to be an historic event for fans of the franchise," said Eric Hirshberg, Chief Executive Officer of Activision Publishing. "The addition of Dropkick Murphys just makes XP that much more memorable. Few bands fit the bill better-we're thrilled to have them performing on opening day."

Tickets for Call of Duty XP will be available for $150. Activision will donate 100% of the ticket sales to The Call of Duty Endowment, a non-profit, public benefit corporation that seeks to help veterans transition to civilian life, find work and establish careers, and assist other organizations that provide career training and job placement for veterans.

Tickets will go on sale July 19, giving attendees a two-day pass and the chance to be completely immersed in the action and excitement of Call of Duty. Players will be able to challenge each other in a paintball firefight on a life-sized Call of Duty multiplayer map, as well as attempt to speed-run Call of Duty: Modern Warfare 2’s legendary “The Pit”—for real.

Other Call of Duty XP activities include:

• Tournaments and prizes for the hardcore and casual fan alike
• Discussion panels and Q&A with Call of Duty developers
• Onsite Call of Duty armory and museum
• AAA live entertainment
• More attractions to be announced

Call of Duty XP precedes the year’s most anticipated entertainment launch on November 8th when Call of Duty: Modern Warfare 3 strikes worldwide, as well as the launch of the innovative new online service, Call of Duty Elite, uniting Call of Duty’s 30 million fans to create a connected entertainment community via dedicated social networking, original entertainment programming, events, competitions and more.
