actions such as moving and destroying objects with the lightsaber or force powers. The PlayStation 2 and Xbox versions of the game feature a multiplayer duel mode, in which two players face off against each other in a lightsaber battle. Players can choose Obi-Wan Kenobi, Anakin Skywalker, Count Dooku, General Grievous, Mace Windu, Cin Drallig or Jedi Padawan Serra Keto. Darth Vader and "Ben Kenobi", circa Episode IV, can also be unlocked. Each battle can be won with the best of one, three or five rounds, depending on the options chosen. In addition, all characters have equal health and energy, with all status upgrades acquired by Anakin and Obi-Wan in the single-player mode eliminated. However, all of the upgraded techniques and Force Powers are available and each of the other characters has special abilities and maneuvers. In addition to the original costumes found throughout the single-player campaign, each character has a different costume that is used when both players choose the same character. Some of these costumes depict Sith versions of certain Jedi characters. With the successful completion of certain missions in the single-player campaign, bonus scenarios can be unlocked. Each scenario features a different playable character: the MagnaGuard, General Grievous, Yoda, Anakin, or Darth Vader. In addition, there are four cooperative missions in which two players (or one player and a computer-controlled character) work together to defeat enemies. The first three team up Anakin and Obi-Wan for a number of offensive encounters with the Separatists' droid army, while the fourth has Jedi Master Cin Drallig and his favorite student, Serra Keto, teaming up to defeat the clone squadron bent on destroying the Jedi Temple in accordance with Order 66. Handhelds The handheld versions of the game are played as a 2.5D side-scrolling beat 'em up game, where players can freely choose to play as either Obi-Wan or Anakin, traversing across roughly a dozen levels to battle a variety of enemies and occasionally dodge deadly hazards, such as a laser trap or a missile launcher. Both characters have nearly identical attack moves, and can gain access to special unlockable moves that can be unleashed when a "fury" or "focus" gauge is filled up during battle. A few levels involve boss battles against characters with melee weapons, who usually can only be damaged after the player carefully recognizes and blocks an attack, and some other levels end with a miniboss fight
