As one of the hottest first-person shooter franchises in modern history, Call of Duty is giving back to the gaming community this weekend in Los Angeles. The two-day event is called Call of Duty XP and upwards of 6,000 people are expected to attend the affair headlined by performances from Dropkick Murphys and Kanye West.

The 24-hour long event gets under way today at 10am local time and runs for 12 hours, with the process being repeated again on Saturday. Fans of the series will have the opportunity to play Modern Warfare 3's multiplayer mode a full two months ahead of launch as well as participate in a host of COD-related live events, such as playing paintball in a real-world recreation of Modern Warfare 2's Scrapyard map and chowing down at Burger Town.

There is also a four-player, 32 team multiplayer tournament with a total of $1 million in cash and prizes up for grabs. All but four slots have been prefilled for the tournament, but if you don't make it into the big show, there are still plenty of other prizes to be won via smaller multiplayer challenges.

Tickets for the two-day event are $150 which includes a copy of Modern Warfare 3 Hardened Edition when it's released. All attendees must be 18 years of age or older. 100 percent of ticket sales go to the Call of Duty Endowment fund, a non-profit organization that helps veterans find work and establish a career as they transition back to civilian life.

Do you plan on attending or know anyone that is? Two of my friends put together last-minute plans and flew cross-country for the event. If you can't make it out like me, you can watch the events as they happen via Livestream.
