Thanks, I wasn't sure how that worked.
Vault-tec is a fake company from the Fallout video game series (and now TV show), that was doing all kinds of social experiments on people living in their underground vaults following a large scale nuclear event across the globe. Timeline wise it's set in the 50s/60s, so has a great 50s diner style asthetic in all the design.
You may have seen the Vault boy; he's been meme'd around since the days of dial up internet, and has been around since 1997.
Vault-tec in the game was a bit of generic Acme co that did everything, but had a huge defence contract for the government and got up to all kinds of evil corporate shenanigans, because they could.
They've done a great job with the tv show, with Season 2 coming out soon, so it's worth checking out if you like post-apocalypse type shows.
