Hey, I was wondering how to get into the Vault-Tec HQ Mainframe. I had already completed Agatha's Song without using the HQ, but now I'm just going around exploring and whatnot. Apparently a key is required to get in, but I don't know where to find it. The article on this site doesn't mention it at all...


  • Read all the terminals in the building. You'll find instructions on how to unlock the mainframe. Snicker 19:32, 12 January 2009 (UTC)
