While I think most of us can accept fallout shelter is pretty awesome, it lacks a lot in some areas. Looking at the ability to create settlements, it's obvious that people will be able to mod the worldspace to provide more areas to build them. However, Wondering the likelihood of mod capability of being able to create underground settlements that use already existing vault assets. Why defend from raiders and such when you can have everything behind an impenetrable vault door! (Obviously different from the one in shelter where raiders can break through with melee weapons)

we havent seen all the places were we can build a settlement so a underground vault could be possible as a location for a settlement.

If it's not in vanilla, you can bet someone will mod a door into a hillside and let you create your own vault. Or at least repurposed an existing one

Definitely want a vault settlement wither its vanilla or mod.

God I hope not TBH...I only want official vaults, or I'll mod one into the game lol.

from the trailer i got in love with that settlement over a water body, and if they allow me to build one on a ship i will be happy if not i will mod it =P

I haven't watched it in a while but I really liked the multi-tiered one with little walkways to the different buildings. Reminded me a lot of megaton

Because you need food and the raiders are stealing your brahmin caravans

Underground farms

oh something like that town in fo3 andyville? Man I forgot the name

Tossing up some support beams, stairs, and scrap-metal walls seems a bit more possible/practical than excavating thousands (millions?) of cubic yards of earth & stone for a vault.

What's easier. A bit of digging to make an underground vault, or making realistic androids? Don't ruin the dream man!

Damn your name making me to want to watch Its always sunny!

I could see repurposing an already existing vault into a settlement. But digging a vault from scratch--to me that sounds like something for a mod, rather than something you could do in-game, with your character alone. I would compare it to building a 10 story building...you'd need some help.

But maybe if you could get to a point in the game where your character has enough power/influence to undertake a project like this...that would be different.

Please... no... How would you build a underground settlement with high developed technology...? Vaults are pre-war stuff...

Aliens!!

Nice idea OP. If it ain't in the main game, hopefully someone will mod it.

I don't really think that there will be any vaults you can take over in the vanilla game, but I'm sure within a month there will be mods that add vault settlements into the game - and within a year there will be a decent mod for it.

If there is no one else left alive in Vault 111, then we should be able to squat there for a time and perhaps modders will make it to where you can repurpose it as a settlement

maybe there is a vault that we can use for live in it, or at least part of eat with outside buildings too. =D
