Call of Duty: United Offensive -- Expanding on the award-winning, epic and cinematic first-person action of Call of Duty, Call of Duty: United Offensive delivers more of WWII's most legendary conflicts by offering over 10 new levels in an all-new single player campaign, as well as nine new multiplayer maps.

With enhanced special effects, improved graphics and new character abilities, Call of Duty: United Offensive offers more realism than ever before. Climb aboard authentic WWII jeeps, tanks and motorcycles, call in artillery strikes, and gain aerial support from fighter planes. With 14 new weapons at your disposal, you can cook off grenades, use a flamethrower or even bring out a deployable machine gun. Fight through snow and rain that impede your visibility, as you avoid spectacular explosions in realistically created wartime environments.

Experience the gripping combat of WWII through the eyes of Allied soldiers fighting for the liberation of Europe. Join the 101st Airborne for the climactic moments of the Battle of the Bulge. Fight as a British airman shooting down German ME-109s from the gunner position of a B-17 bomber, before transferring to Churchills elite S.O.E. and clearing the way for the invasion of Sicily. Follow your Russian comrades to experience the awesome firepower of tank warfare, both in the trenches and aboard T-34/85 tanks during the historic 8-day Battle of Kursk.

Go online for the ultimate battle between Axis and Allied powers, now including tank combat as well as tank-and-foot-soldier combined arms action. Experience 8 new multiplayer maps and 3 new modes -- including Tank Battle, Capture the Flag and Domination -- where squads must take control of key locations while preventing enemy troops from advancing. A new ranking system lets you earn additional weaponry upon completion of objectives, and gain the respect of friends and foes alike.
