So Im at the end of dead money, I got the optional objective to sneak out and trap him in the vault. But even with a stealth boy whenever I get close to the elevator the force fields go up, what am I doing wrong?
The only way that I know of is to use a stealth boy and go straight out of the vault door up the stairs right in front of you, go into the little room and follow the right path to the door he came out of and once you reach the door you are free.
Unless Im mistaken.........You have to run back through the whole thing, past all the hologram guards and everything. It sounds like a lot, but in reality it takes about 30 seconds. As soon as you finish talking to him on the screen, leave the vault and head for the door on the far left....then run through everything, and youll come out at the begining.....right where you see him coming from. Hell be tring to attack you, but the force fields will be up and you just leave. Any other route you take brings up the force fields.
There's a bunch of you tube videos on this...just look up " traping father elija in the vault"
You're probably trying to sneak off too early. Wait until he's definitely not going to see you, so when he's a metre away from the door or something. Don't forget to stay in sneak mode until you're very sure that he won't notice. --- GT: Fiery J.
