However, there are ways to experience the game from the Separatist side:
* Free Play: After completing a level, you can replay it in "Free Play" mode. In Free Play, you have the option to switch between any character you've unlocked, including the bad guys.
* Character Select: The main menu of the game offers a "Character Select" screen where you can choose any character you've unlocked to play in a variety of challenges and minigames. This includes villains like General Grievous, Count Dooku, and Asajj Ventress.
* DLC: Some downloadable content (DLC) for the game adds new characters and missions that allow you to play as villains.
While you can't play through the entire story as a Separatist, you can definitely enjoy playing as them in various ways after completing the main game.
