WWII is the first title since the original game and Call of Duty 2: Big Red One not to feature health regeneration in the campaign. Instead, players must find health packs scattered throughout levels, or rely on their medic squadmate to provide health packs. Other members of the player’s squad can provide ammunition, grenades, call in mortar strikes, or spot enemies and reveal their position in form of silhouettes. In certain sections of the game, enemy soldiers in the campaign can be captured, and wounded allies can be dragged to cover. In some parts of the campaign, players are able to control vehicles.
