How to get through the 2nd hall:
1st you have to run across the hall (not crossing the bridge yet) and you'll see a ramp, go up it and kill the guard. You should see a bule rock:push it down. Then go to were it landed, and push it forward onto the button. When you do that Gimli will be attacked, you can help him but he can take care of himself. Now hop across the brigde and, hop over the cracks. When you get to the big gap push Frodo aganist the piller and hell start to climb. Then just walk the rope and your out of there.
