Despite an early morning traffic jam that actually delayed the keynote by about 30 minutes, the crowd has settled in to the exhibits here at the Call of Duty XP show in Los Angeles today. There's lots of gaming going on, featuring Call of Duty: Modern Warfare 3 multiplayer and Spec Ops Survival mode, as well as Call of Duty: Black Ops' King of the Hill and Zombie modes. Outside, paintballers are playing on real-life replicas of MW2's The Pit and the Scrapyard multiplayer map, and grabbing grub from a full-size replica of a Burgertown franchise.

You can see all the action in the gallery below. Later on today, Activision is holding a few panels, talking about both clan support in the new Call of Duty Elite service, as well as voice acting in the series as a whole. The Dropkick Murphys are playing a closing concert this evening, and there's another whole day of activities and sessions going on tomorrow.

Stay tuned -- we'll have more coverage from the show on both days (minus, of course, the $150 cover charge).
