Call of Duty: United Offensive

This adds three new single-player campaigns as well as expanded multiplayer modes. There are 13 new single-player levels, plus an enhanced multiplayer experience with 11 new maps and 3 new modes of play, also including vehicles. You are again looking through the eyes of American, British and Russian soldiers. As a US soldier in the 101st Airborne you are in the Battle of the Bulge. Afterwards you start as a British airman in a B-17 plane, operating the board weapons. After your plane was shot down and you escape with a parachute, you sabotage a German train together with some members of the Dutch resistance. Impressed by your skills, a SOE-Officer recruits you for an attack of a coast fortress to support the invasion of Sicily (known as Operation Husky). The Russian campaign plays during and after the Battle of Kursk, the largest tank fight so far.
