LucasArts has answered the following question about Jedi Outcast:

How does multiplayer work in the console versions of Jedi Outcast?

Multiplayer in Jedi Outcast for Xbox and GameCube is called Jedi Arena, and players can choose to play full-screen by themselves or split-screen with a friend. In addition to the human component, players can pick from a group of 28 separate bots including such notable characters as Luke Skywalker, Jan Ors and Mon Mothma. These 28 bots are not just the same enemy with a different texture. Rather, each bot is a unique AI character with different skills, priorities and preferences. For example, Imperial Worker bots behave differently than a group of evil lightsaber-wielding Reborn Jedi. Well, there you have it!
