If you're not a Call of Duty Elite subscriber, you'll finally get your hands on Modern Warfare 3's DLC next month. Today Activision announced that Content Collection #1, a compilation of all the new content released for the game so far, will hit Xbox Live on March 20th.

MW3 Collection #1 includes the three multiplayer maps already available to Elite subscribers on the Xbox 360: Liberation, Piazza, Overwatch. It will also come with a new multiplayer map called "Black Box" and Spec Ops missions "Black Ice" and "Negotiator."

"In 'Black Box,' players will battle beside a downed Air Force One amidst multi-level homes overlooking the luxurious Southern California neighborhood," says Activision of this new content. "Infiltrating a diamond mine aboard a snowmobile in the Special Ops mission 'Black Ice,' your primary objective is to plant high-grade explosives in order to shut the mine down forever. In 'Negotiator,' you head to India for high-stakes hostage extraction in which you'll breach-and-clear rooms and navigate surface streets to ensure the safety of your VIPs.

Elite subscribers will be able to download "Black Box," "Negotiator" and Black Ice" through Xbox Live on March 13th. This DLC, along with Content Collection #1, will hit other platforms at a later date. Expect to wait at least an additional month if you don't own an Xbox 360.

Activision plans to release 20 pieces of DLC for MW3 by September.
