So I'm up to the point where you need to get the G.E.C.K. from Vault 87 but I can't get past Little Lamplight. Mayor MacCready does not have the dialog option to open the tunnel gate and Joseph does not have the dialog option to power up the terminal for the back door. I did finish the quest to rescue some of the kids from Paradise Falls.

Yes, the place annoys me. After the third time of talking to MacCready, he then mysteriously decides to open the gate for me. I can only get the power for terminal turned on if I first talk to MacCready, find and talk to Joseph, go back to MacCready, then go back to Joseph. Basically I talk to everyone in there, multiple times, until someone gives it up. Wouldn't hurt talking to Biwwy too, I imagine.

I've tried talking to them several times each. Even went back and forth between MacCready and Joseph but still no luck. I really would hate to have to reload the game so far back as to have never been there.

I don't use mods and I've never used cheats...................until this quest.I had to come here and get help since I had no idea how.I had to open the console and open the door to Murder Pass (I think that's the name of it) and I still had trouble because I kept falling through the floor.It took a while of playing with it but I finally got it.Good luck.

What is the command to open the door?

I can't find my notes but if you search the forum, the topic I started was "Stuck in Little Lamplight" .It said to check Vault 87 and picking up the trail bug section.That's where I found the answer.Hope this helps.

The "tcl" command to clip though the gate worked like a charm. Thanks Grace1957.

I dunno, I guess maybe I just got lucky - it took me a while to find joseph, but at least when I finally did, he was quite happy to power up the computer for me. Of course, it then took me like 30 attempts at hacking the computer to find the right password. ( Man I hate the password hacking mini-game. Until I got to almost 100 Science, I swear I could basically find no better method of hacking then to just randomly try three different passwords, then close the terminal before lockout, re-open it, and try 3 more random passwords. The 'clues' they give you seem mostly useless most of the time. About the only benefit I managed to get out of the clues is that, let's say there were a bunch of words ending in -ing, or -ion, and I picked one of those words and it said 1/X matches, then I at least can figure out that the correct word doesn't end with that suffix - I guess that's a slight help, but still seemed like there was a high degree of random guessing till you hope you eventually get lucky).

You're very welcome.I'm glad I'm the one helping this time instead of freaking out because something isn't working and I have no idea what to do!
