Star Wars: Battlefront II, also shortened to "Battlefront II", and alternatively abbreviated as "SW:BF2" or "SWBF2" is a first-/third-person shooter video game developed by Pandemic Studios and published by LucasArts, and was released in North America on November 1, 2005, for the Xbox, Playstation Portable, PC, and the PlayStation 2. The PC variant comes in two type of disks: CD-ROM, which comes with four disks, and DVD-ROM, which has only one disk.
It is the second game of the highly successful Star Wars: Battlefront Series and a sequel to the original Star Wars: Battlefront. There are several differences between Battlefront II and the original Battlefront, such as playable Jedi characters, two new unit classes, space-based dogfighting, and story-based campaigns. The release date coincided with the release of Revenge of the Sith on DVD.

Battlefront II expands upon the original game's single-player experience with mission-based objectives drawn from Attack of the Clones' Battle of Geonosis to The Empire Strikes Back's Battle of Hoth. It is a story-based campaign told from the view of an unidentified 501st clone trooper; it revolves around the 501st Legion as the unit evolves from the Galactic Republic's Clone Troopers to Imperial Stormtroopers. The plot spans more than 16 new locations, many from Star Wars Episode III: Revenge of the Sith, including volcanic Mustafar and the space battle above Coruscant. Many maps that came from the original Battlefront were edited to fit more accordingly in the storyline, such as the Naboo battlefield, which was originally Plains, but due the clones' lack of action upon the Invasion of Naboo conflict between droids and Gungans, the setting is shifted to Theed. Also included are battles from the original trilogy, such as fights aboard the Tantive IV, Princess Leia's blockade runner shown immediately at the beginning of Star Wars Episode IV: A New Hope.

Being a successful hit, the game are now considered on the following: Xbox Platinum Hits, a Sony Greatest Hits, Xbox Classics, a Lucasarts Fan Favorite, and Playstation Platinum.
