Have any of you guys ever successfully done it? I've never been able to, without the host using cheats. I've gotten close with a few groups, but the. We make a mistake.

I did it once, with three people. One on the cameras, passing coke, setting shit up, another hacking the computer and keeping guards away and another inside, killing some guards and avoiding the rest. It's pretty hard and you need bag shortcuts AND a good safe location. You should be able to spot the guards coming by they're torches, which go through walls for some reason. That is if you're on next gen and PC.

I do recommend using voice chat/text chat, to tell the guy with the coke when to drop bags. I also recommend getting the other guys to help you with the gold if you plan on taking it.
