How are you guys doing this?
I tried following http://www.youtube.com/watch?v=rYuJb0_TbwM, but the blue energy shield on the door shuts off just long enough for him to step through, then immediately turns back on, making it impossible to do what is shown in the video.
Also, trying to drop the bars 'through' the energy shield doesn't work either...they just bounce off.
Argh. This DLC was a gruelling endurance test of patience, with very little fun for me. Making off with all the gold would take some of the annoyance i feel at buying it...
I don't know how that kid is pulling it off in the video, because that shield is designed to come down when you reach a certain distance from it.
Dropping the bars in the right spot is extremely annoying. In the several times I've been through the DLC, I've only managed to drop them on the other side one time. All the rest, I drop them (after many tries) very close to the shield, run around, and use the camera-glitch-grab technique to get them and get out about half a second before my collar goes. You need to be just the right distance from the shield when you drop the bars or they fall too far, or just fall off the edge. But this method is possible.
After all the annoyances of the DLC, and the annoyance of trying to get all the gold, it is VERY satisfying to walk out of there with all 37 bars. Very, very, very satisfying.
