Hey so im trying to get all the gold out of the siera madre and i generally do the glitch where you drop them through the force field and its not working to well is this patched or am i just not aiming right (ive done it before) any help would be appreciated thanks!

Doesn't the original method of using a stealth boy still work?

You don't need to glitch.

What you do is you take them all, have the conversation with Elijah and imply you're going to rob him blind. He'll then head down to take care of you. Once he does this, walk out the door of the vault and get in sneak mode behind this generator thing between the vault entrance and the doorway Elijah comes from. Elijah will SLOWLY make his way to the vault door, slow enough so that you can go around the generator, taking care to make sure he stays on the opposite side of the generator from you. Now, once Elijah is on the side of the generator near the vault entrance (your starting position basically) and you're on the side of the generator near where he came from, this is where it gets tricky. You CANNOT keep going, as the moment you set a foot near the platform with the stairs up to where he came from, he'll automatically detect you. This means that once you're on that side of the generator, you need to STOP once you're directly behind it from the perspective of someone standing near the vault entrance. When do you move again then? Wait until he approaches the vault door terminal. The MOMENT he gets near that terminal, close enough to activate it? Get up. Stop sneaking and straight-up WALK to the doorway he came from.

It's very clutch, VERY close timing, but it can be done. I do it all the time. I know my description isn't the best (hard to describe with just text), but the only difficult parts are:

1) Deciding how close you can get to the stairs leading to the exit once you're on the exit-side of the generator. He's actually very sensitive about them, so you have to keep a pretty damn reasonable distance from them. As I said, best to just stay directly behind the generator. "Behind the Generator" as in, if there's a north, south, east and west side to the generator with you STARTING at the west side of the generator, going counter-clockwise around it and moving south then east to mirror Elijah, STOP the moment you're directly east of it. Trying to go even the SLIGHTEST bit northeast of it will set him off.

2) Deciding when to book it for the door. Can't start too early or he'll notice, can't start too late or you'll see him activate the forcefield right before your very eyes. In my experience, you basically wanna book it the moment it looks as though he's taking his LAST steps towards the vault terminal. On my game Elijah takes like 3 steps, briefly pauses, three steps, briefly pauses. The LAST set of 3 steps before he'd be within reach of the terminal and able to activate it; that's basically when you wanna book it. Perhaps not at the very start of the 3 steps, but in the middle of them, yes.

Score!!! I made it out with ALL the gold this time. Had to try it a few times to get the timing just right, but I walked up the steps and through the doorway a half a second before the force field came on. Mr. Elijah was not pleased with me, to say the least

I think I did it by throwing down 20 bombs just cause, then walked to the back door and blew him up... something like that.

It's not really worth it though. The gold bars' value to weight ratio is 301 caps, which isn't a whole lot. The V/W of a police gun is 333 caps, Lever-Action shotgun 666 caps, etc.

Lots of gas bombs and demo charges at the door Elijah stands behind.
As he stands there giving his speech I'm crouched and walking into the left corner of the force field.
As soon as that force field drops we will switch places and hopefully my EXPLOSIVEs skill is high enough for my mines to kill him instantly.

I tried a whole bunch of different ways but after failing just walked up to the force field dropped them and they fell right through....yay.

i just killed him using all i got, and then made it out with 6 gold bars, and made enough money out of them + all the pre war money to buy supplies and weapons enough to help me get through OWB easily (well sort of easily) Now im on Lonesome road, kinda have problems with caps as i want to upgrade all my things (having a little deathclaw infestation problem) and it just gets harder and harder. Almost out of ammo, and caps.
Point is taking all the gold bars isnt worth a sneak attempt past Elijah, rather just murder that a hole.

OMG I always took the LONG way around! I played through the DLC once, and my head exploded so many times when I tried to escape the vault! Cool, I'll so try your method in my current play through!

Ugh... I was doing it today and it took me a while to figure out. But this short YouTube video told me everything I needed to know.

watch?v=y2fFsGNcZc0 (just copy the end of the URL since it won't let me post full links, or just search for "fallout gold bars" and it's the ~2 minute video)

Right now I have to walk back to the Lucky 38 with all that weight on me. It didn't help that the game froze about 20 minutes in.
