In Campaign Mode, the player follows the campaigns of the 501st Legion as told through the Journal of the 501st. As players progress through the game, they play as a clone trooper during the reign of the Republic and as a stormtrooper during the reign of the Empire. The action brings players to multiple planets through a story arc that stretches from the dawn of the Clone Wars to the formation of the Empire and later, bridging the gap between Episodes III and IV. Unlike the first Battlefront, Battlefront II's campaign gives players certain objectives with a given number of reinforcements with the enemy's reinforcements unlimited and an occasional time limit rather than playing an ordinary conquest match. The game also gives the option to skip space missions.
