If you are in a multiplayer battle then make sure you pick the right carechtar. If you are against a person who is seriousoy good at the game (Like me) then use General Greivous. If you are against someone easy then use whoever you feel like. All the carechtars have their strengths and weaknesses, experiment with them. You will soon find out things like who has the most power and who is the most agile.
I'm only telling you all this beacause it took me 3 days to realize this so at the bit where you are obiwan kenobi and there is a clone ship staring at you while tryin to blow you up you just lighhtsaber throw
