EA is pulling out all the promotional stops to pump out new media assets for Army of Two: The 40th Day. Their latest marketing effort for the game includes new gameplay footage of the demo, which is due out on December 17th.

The footage contains a brief cinematic of some overhead shots with Hong Kong being blown to bits, and then it quickly gets down to business and gives gamers what they came to see: two buff dudes with big guns using co-op mercenary tactics to lay waste to other mercenaries.

You can check out the new footage below or visit the Official Website for more information. Army of Two: The 40th Day is due out in January, 2010 for the Xbox 360 and PS3.
