Call of Duty: United Defense

Join the 101st Airborne for the climatic moments of the Battle of the Bulge. Fight as a British airman shooting down German Me-109's from the gunner position of a B-17 bomber, before transferring to Churchill's elite S.O.E. and clearing the way for the invasion of Sicily.  Finally, follow your Russian comrades into the Battle of Kursk, one of the greatest tank battles of all time.  The war that changed the world rages on.  Fight in tanks, jeeps, motorcycles, even a bomber. Work with your squad through snow and rain, using new weapons including flamethrowers and deployable machine guns, or by calling in artillery strikes.

On air, land or sea, one thing has remained constant throughout history - in war, no one fights alone.  From the skies over Western Europe to the rolling plain of Russia, the Allies stood together against their common enemy and prevailed. In Call of Duty: United Offensive you will be immersed in some of the most decisive battles of World War II.

Become Corporal Scott Riley as you and your brothers in the besieged 101st airborne hold out in Bastogne during the Battle of the Bulge. Relive the career of S.O.E. operative James Doyle from your last bombing run as a gunner with the R.A.F. to the invasion of Sicily in 1943. Assume the role of Conscript Private Yuri Petrenko as you and your comrades take part in the events of the summer of 1943, from the Battle of Kursk to the final battle for the city of Kharkov.

Whether in a small unit sabotaging an enemy train in occupied Europe, or part of an entire tank division advancing across the Russian steppes, one truth rings through: success in battle cannot be realized by any one man. Adversity cannot be overcome without unity, and victory can only be achieved through a United Offensive.
