Well I registered just to post for help here.

I can't get passed the ending where I have to kill Elijah or escape from him. If I kill him I go and run to the marker on the map there is a barrier blocking for where it says to go. So option 1 is gone. If I try to sneak past him I get to the elevator and it says "elevator cannot be called down from the vault"

WTF do I do literally I've been trying and looking up solutions for the past hour. I can't find anything on it.
