Star Wars: Battlefront (2004)

Plot

While the game is played similarly in every mode, each is a unique scenario which utilizes mode-specific features to further extend gameplay. Three modes are presented to the player: Campaign, which serves as the game's story mode, Galactic Conquest, in which the player must conquer planets, and Instant Action, which allows the player to select the battle they wish to play and adjust settings such as reinforcements to their liking.

Campaign groups several battles together in a set order loosely based on the historical campaign of either the Clone Wars or the Galactic Civil War. As Episode III had not been released at the time, the Clone Wars campaign ends with the Battle of Kashyyyk. Footage from the five films then released are used as cutscenes between battles. The player starts the campaign as either a member of the Separatist army or an Imperial Stormtrooper. Around halfway through the chosen campaign the perspective switches to the Clone Troopers or Rebels. To maintain continuity, missions prior to the battle of Geonosis pit the Separatists against native forces only, and for the first two missions the super battle droid is unavailable, replaced with a standard battle droid.

In Galactic Conquest, the player uses strategy to take control of planets and dominate an area of the galaxy. First the player chooses a map configuration based on conflicts from both eras of Star Wars history. Some maps start both sides evenly while others favor one faction. Next, the player chooses which faction to play as. The game is played in turns, with the player starting first. The player can select an enemy-controlled or neutral planet to attack. After selecting what planet to attack, the player is able to activate a bonus from one of his already owned planets (if any). Each planet provides its own unique bonus, but must be captured before the player can use it. Bonuses help the player in battle by impeding the enemy or assisting the player's team. If one side manages to win four battles (not necessarily in a row), they gain access to their faction's Secret Base bonus. Secret Base bonuses are very powerful and can change the course of a game. They can be used on any enemy planet, except for the enemy's Secret Base. The game is completed when one faction controls all planets on the map.

Instant Action mode allows the players to jump right into a battle of their choice. The player can also customize a list of battles, which then can be played through in the order they have chosen, or in a random order. Players can choose between playing as the Republic, the CIS, the Empire, or the Rebels on each of the maps, except Kamino, Geonosis,Endor and Hoth, which do not allow the player to select their battle era, as these follow their canonical settings. Players can also choose whether or not they would like to have heroes fight for each side.
