No it isn't. There are tons of different strategies to do this. Hold on, I'll find the strategy that worked for me.
EDIT: Here it is, found on the Vault:
By far the most elegant and easy technique I have seen yet. It worked for me and was confirmed by 3 others on the Vault, but sometimes it takes a few attempts to perfect. Good luck! :wink_smile:
Thanks for the detailed notes. Does it matter which circumstance under which Elijah comes down? I’ve tried “let’s cooperate” and “I’ll steal it for myself” both of which get him hustling on down to the vault. I’ve tried crouching by the generator thing at the base of the stairs Elijah comes down, with it between me and him, but he ~always~ stops on the stairs and “sees” me crouched there and starts talking, with or without stealthboy active and with or without the assassin suit on, and then Elijah doesn’t move off the steps to get to the console part.
I’m assuming that when he walks past you and activates the console by the vault door
that is when the shields blocking the doorways will go off/down and let me through. When Elijah is at the computer I guess he doesn’t notice you standing up and leaving and instead must be fixated on going in the vault. I’ll try that strategy a few more times (I’ve seen it done on walkthrough videos without using stealthboys) so I know it’s doable. I may as well grab everything in the vault of value as once you’re over encumbered it doesn’t seem to matter if its just 1 pound or 10000 pounds over the weight capacity.
