Two Modern Warfare 2 Map Packs Hitting Xbox First (Update: HD Gameplay Footage Added)

Developer Infinity Ward today took the stage at Microsoft's E309 Media Briefing, announcing that the Xbox 360 will receive two downloadable map packs before any other platforms and walking attendees through a mission called "Cliffhanger."

The mission began on an icy ledge, with players forced to climb up the side of a mountain by manually swinging ice hooks, via the triggers on the Xbox 360 controller.

The relatively quiet mission devolved into a firefight on an airfield, with enemy troops ambushing the on foot and on snowmobiles. The player then commissioned a snowmobile, speeding through the snowy wilderness whilst shooting a gun.

Expect more details as our E3 coverage continues. The game itself is due on PC, PlayStation 3 and Xbox 360 on November 10.
