Admittedly, they did a bad job here. I searched for the forking lift for 5 minutes because I thought I couldn't move through the backstage area.
Heh! Same with me... kept fighting Rock leftwards down the hallway, saw no lift and thought I missed it where you start off. Fought Rock back to the starting point... nope, no lift. Back down the hallway and so on until I found you could go downwards to the garage. They really need a better camera for that crap.
