How to get more dwellers fast

There are several ways to gain more Dwellers

• The Radio Studio is an option, but you need 20 Dwellers to unlock it; and when manned by low-charisma dwellers, attracting new Dwellers might take some time. Note that Charisma can be boosted with certain Outfits.

• You can put two Dwellers together in your Living Quarters. Conceiving might take some time (note: the right Outfits also help here), as well as carrying the child and having it grow out to be an adult. There are however no pre-conditions for this approach, the outcome is pretty much guaranteed.

• And lastly, you can send Dwellers into the Wasteland. Occasionally, your Dwellers will stumble upon a Red Rocket Truckstop, a Super Duper Market etc. Once in a while, there's refugees in there that want to join your Vault. Also, these explorers might find Outfits that boost Charisma, to help with the two points above.

Sometimes it's a struggle to catch back up, but the only thing you can do to directly get dwellers more quickly is get your dwellers to make babies. Other than that, just try to get your shelter back to operating as well as possible, as well as having room for more dwellers to come by.

You can also have a certain room that you can assign a dweller to that will let a dweller use a radio to call out for more dwellers. You have to have 20 dwellers before you can get the room.
