If you're under level 20 and you're looking forward to jumping straight into Vault-Tec Workshop, Fallout 4's second last slice of downloadable content, then you should know that you'll have to do things the hard way. Only those at level 20 or over will automatically trigger the add-on's initial quest when they load up their save - those who fall under level 20 will have to trigger it manually.
As detailed in yesterday's livestream, players will have to journey to the South of the Commonwealth in order to follow the DLC's story. There's no grand tale on offer here, but the location that the quest takes you to is ready and waiting to built into a big old vault. Again, if you're level 20 or over, you'll get a quest marker telling you where to go once you listen to a specific radio broadcast.
Lower level players will have no choice but to stumble across the quest themselves, though. In this particular case, you'll trigger things by approaching the Quincy Quarries - but be warned: there could be some tougher enemies hanging around that area.
Are you looking forward to creating and running your own vault? Run some questionable experiments in the comments section below.
