So I got to thinking... Where is post-apocolyptic Vault Tec? I mean the antagonist in every Fallout game Bethesda has made is a faction other than Vault Tech. I mean here you have a private corporation that has reached the penacle of the war-industrial complex. They have highly advanced tech, are extremely secretive, obviously had a well organized and successful plan in place for multiple vaults all over the country. Were committed to doing vast experiments in supposedly thousands of vaults. There is absolutely no way they were caught off guard by the bombs. It's what they were counting, or dare I say, planning on. They obviously have a vested interest in making certain the bombs do actually drop and that a nuclear war happens. So why has Bethesda never saw the need to include them in one of their games? I mean with everything Vault Tec pulled off they would make the institute sit at the kiddy table.
Why not have a Vault Tech protagonist that is only defeated in part and not destroyed for the final DLC that leads to a huge Vault Tech villian in the next big Fallout game? The potential here is so story and lore rich that it allows for all sorts of options. We finally get to learn why Vault Tech wanted to conduct these experiments, what their role may have been in dropping the bombs, and what they stood to gain from all their nefarious plotting. Perhaps they were secretly allied with China or Russia and were promised control of the US for helping destroy it? Perhaps they have a civilization off somewhere in North Dakota that is unaffected by the bombs and still a very pleasant place to live? Perhaps their leaders found a way to preserve their life like the Cabots did, or willingly froze themselves as well so as to continue their research into the future?
So where is Vault Tech?
