Each will have different outcomes depending upon player choice as they act like a proper Overseer. Players will need to recruit folks to live in the Vault and as mentioned above, players will be tasked with running a series of experiments on them. More information is available on the Bethesda website if you aren't worried about spoiling the questline.
We won't tell you the rest, because we don't want to give away the storyline. Fallout 4 players at or above level 20 will need to take care of raiders upon arrival and once they are dispatched, the player will meet the Vault's 'strange Overseer' who is the sole survivor. It all starts out with a distress beacon coming from Vault 88. Players will be provided with everything they need to create their own Vault with various new items, and the ability to perform experiments on those who move into your dwelling. Fallout 4 players will be able to create their very own Vault next week, and today, Bethesda dropped a few more details on the Vault-Tec Workshop.
