Opposing Fronts is a stand-alone expansion for Company of Heroes. It introduces two new factions: the British 2nd Army and the German Panzer Elite, each with its own command tree. The British have Royal Canadian Artillery, Royal Commandos and Royal Scottish Engineers while the German Panzer Elite focuses on vehicles and speed with halftracks and Panzergrenadiers. They can also salvage destroyed axis vehicles with the Bergetiger. Panzer Elite has access to 3 doctrines: Scorched earth, Luftwaffe and Tank Hunters.
There are two new campaigns, based on the battle for Caen, France and Operation Market Garden. The game also features improved AI and a dynamic weather system. For the multiplayer games, owners of the original game can pick any of the 4 sides. Players who only bought the expansion can only choose the 2 new sides, similar to how the Dark Crusade expansion functioned.
