When you are at the queen's last part of the final battle, when you start take out all the droids in the room.(with your favorite blaster or the tripod gunner.) When you get to the big door where the throne room is behind, go to the left where you and panaka take out the battle droids. There will be an idol next to the door, shoot the idol to get full health.Go into the door and you will find 2 battle droids and an open window. Take out the battle droids and make sure panaka is in the room then jump out of the window (not too far!!) and go to your right until you find another open window. Jump into it and you will find 2 more droids. You will find a button, press it, then a door will open. You will find 4 battle droids, a button, and the viceroy. You have got to the throne room!!!!!!!!!!! Take out the droids and go forward and press the button, the door next to it will open and you find panaka. He says he was worried about you. Go and talk to the viceroy and say anything, he will send droids and let panaka take care of them while you kill the viceroy!
