Darth vader level episode III possible glitch? I am in the final area. I jump across all of the small floating platforms, jump to top of beam as it is falling, then jump to a small platform then to the circular rock floating in lava. Once I get onto the rock nothing happens. We are supposse to have a final fight. Do I need to buy/unlock darth vader to complete free play? I know that many of the characters have the same abilities.I do not plan on finishing the game 100%. Any help would be awesome!
