Funny mission this. One of the BO's always went unconscious somewhere out of reach, had to do it three times before a successful completion. The last time the game decided to reset the entire cavern, that did the trick. :p
This is one of those missions were setting team way points helps alot, especially in fights on the catwalks.
I find it hysterical when one of the enemy jumps off the bridge. Though if they drop an item you can't get to it unless possibly by jumping in after it, and hope you can click on it fast enbough before you die. Good luck with that .
