Ignore my last question. How do you defeat Darth Traya and her floating..

What I did to defeat her is I ran to the left of her down the bridge until only the light sabers were following only and I fought them there. It wasnt hard but they kept waiting for me to get done healing.

I forgot to answer your other question. The game is over for good when you beat it.

Ah, it's really too bad Kreia turns on you like that. But, I guess it's for the best.

What I did is just owned her in the first battle, and then when she summoned the three lightsabers, I ran around the Core. I inflicted them with the Plague, to slow them, and then hid behind a column, so they wouldn't attack me. Then, I just used ranged Force moves on Traya (Force Storm is the best, but you can use whatever you like) until she died. She is really easy if you battle right.

This is a how to kill her on the light side. First just start hammering her with the special power you got. Heal whenever you get hurt. When she gets the 3 purple lightsabers, run! Go across the bridge and watch the sabers come. Heal if you need to and then use force speed to run through them. Use the special power then attack her. Run across the bridge when the lightsabers attack you again and repeat. She really is quite easy.

1. To defeat Traya, make sure your all juiced up on stimulants and that your shields are on before you enter the core room to talk to her. Then use force moves like force wave and force storm straight away (it's harder for her to block these moves) If she gets close, run away! Use more force moves (and even grenades) from a distance. When the floating lightsabers appear, just use force storm continually on them Until they die. Simple. :-)

2. And no, if you restart the game, it's all from scratch.

If you go dark side use crush on traya,and storm on the lightsabers
