To celebrate the release of Call of Duty: Modern Warfare 3 Content Collection 1, Activision has given us five Hardened Editions of the game on Xbox 360 to give away to our lucky readers.

Each Call of Duty: MW3 Hardened Edition contains a code for one year’s Call of Duty Elite Premium membership, which entitles you to all of the previous maps, along with all future DLC releases for the title.

The Hardened Edition also features a copy of the game in a special edition SteelBook Case, special "Founder" status on Call of Duty Elite (including a new emblem, playcard, weapon camouflage and many more benefits), an exclusive Special Ops Juggernaut Xbox Live outfit and an exclusive limited edition collectable field journal featuring the entire saga and authentic military sketches.

Call of Duty: Modern Warfare 3 Content Collection 1 includes an unprecedented level of content for a Call of Duty downloadable release. This awesome package features four brand new multiplayer maps: Liberation - a militarised Central Park in the heart of New York City; Piazza - an idyllic Italian seaside village getaway gone rogue; Overwatch - a construction site atop a NYC skyscraper; and Black Box - a Southern Californian hillside with half-built homes devastated by the downed wreckage of Air Force One.

Also included are two new Special Ops Missions, marking the first time Special Ops have been made available to download in Call of Duty’s history: Black Ice - a high-octane race against time to shut down a diamond mine and Negotiator – where you head to India for a high-stakes hostage extraction.

Call of Duty: MW3 Content Collection 1 is available on Xbox 360 from today, 20 March 2012 for 1,200 Microsoft Points.
