Floating:

This is sweet! OK go to ivory tower and go to the stair case with the over shield. then at the top go to your right and there is a small wall there. jump on top of it and face as if you where walking down the stair case. to your left there should be an air lift. throw a gernade at your feet and gernade jump over the air lift in to the corner. then you will be floating. if some one attacts you with the sword then you will die and your body will float! and the person who attact you will be floating. do this over and over and all the dead bodys will look like a giant octapus! I hope this helps(o and this is helpful if you carry a rocket launcher)
