Star Wars: Obi-Wan
To unlock all levels including bonus levels, start a new game and enter your name as "Greytherat".
At the start of the first level turn around and walk to the end. There is the first waypoint marker and a tall, hairy, ape-like creature. Talk to him (Y) and he will follow you and help you kick some Jin'ha ass... wookie style.
How to Beat Mace Windu & The Tusken War Chief:
Mace Windu is a very hard opponent, that is, unless you know how to beat him. It is actually a very simple strategy. When he goes to hit you with his light saber, just press down on the right thumbstick for an active block, when timed right, Mr. Windu will stumble and groan...allowing you to get off about 2-3 force attacks. When he starts to back away from you, DON'T FOLLOW HIM! If you do follow him, he will use a force throw to toss you, just keep turning to face him but DON'T GET CLOSER. He will sometimes crouch and run at you, back away from him. Only attack when he is standing up.
-Tusken War Chief
This guy is EXTREMELY hard when you ACTUALLY use your light saber, I mean, c'mon! Who would use that. First things first. When his tusken thugs come at you, simply stand on the bridge you start out on and wait for them to come to you and just kill 'em with your light saber. Once they're out of the way, run to the middle of the room and wait for the "big guy". When he gets within range, Force throw the big flaming thing in the middle of the arena at him, this gives you an oppurtunity to force attack a few times, you don't even need to force attack him, you just need to keep throwing fire at him (the thing in the middle isn't the only thing you can throw, there are miniature torches around the main platform you can throw too!)
