Call of Duty: United Offensive

An official expansion to the original Call of Duty, developed by Gray Matter Interactive and released in 2004. United Offensive expands the main storyline with three new campaigns, placing players in the roles of soldiers from the U.S., British, and Soviet armies. The expansion introduces large-scale battles, such as the Battle of the Bulge, the fight for Kharkov, and the British airborne assault in Sicily, delivering even more intense and dynamic gameplay. New weapons, vehicles, and the ability to use stationary machine guns were added. The multiplayer mode features new maps, soldier classes, and game modes, including large-scale team battles with vehicles. With graphical improvements, enhanced sound design, and cinematic storytelling, United Offensive became a worthy continuation of the original game, significantly expanding its gameplay possibilities.
