Modern Warfare 3's First Content Drop Arrives on Xbox Live

Modern Warfare 3's very first DLC offering has arrived today in the form of two new multiplayer maps; Liberation and Piazza.

To celebrate the launch, Activision has released another brand new trailer featuring Rob Riggle, comedian and real-life Lt. Col. in the United States Marine Corps. Check out the trailer above as Lt. Col. Riggle runs us through the finer points of these two maps.

We'll have some hands on with the maps later, to give you an idea of what they feel like outside of the carefully crafted trailers so be sure to stay tuned!
