The story takes the player on different missions throughout the galaxy as part of the Galactic Empire's 501st Legion known as Vader's Fist. The game's campaign mode is entitled Rise of the Empire. Battlefront II, however, includes elements and missions from Star Wars: Episode III Revenge of the Sith, as well as enhanced aspects of gameplay including space combat and the ability to play as Jedi characters or other heroes. The two games are very similar, as both revolve around troopers from various factions fighting in different locales. It is a high-selling Star Wars video game following the many adventures of several characters. Star Wars: Battlefront II is the sequel to Star Wars: Battlefront.
