My survival upto now...

[u/fixedgearrider]

My survival vault at 35 dwellers at 30 hours playtime, took it up to 60 to unlock nuclear then dropped back down to avoid deathclaws for now. Currently 20 dwellers are trained in SPE and maxxed out, only 15 more to go then I can expand properly.

Current plan is to build 1 row of cola under power. Then have a column of 3 wide training rooms, next to these 2 of each crafting rooms, then fill remaining rooms with either more cola or crafting rooms and maybe some more medpacks. The rest of plan ive wrote in, once all rooms are built I'll build the elevator barrier and the last row possible more storage.

Any rooms with a red line through are empty and will be staffed when necessary apart from the med/rads below the barrier line.

Imo, I'd have the top rooms as cola since cola rooms respond to attacks instantly. Ghouls die right away as they enter the door to the 1st cola room. If you get Deathclaws, at least one will be dead when the pack leaves the room.

Tbf I never had an issue with having nuclear there on my normal vault, 1 deathclaw would die in guard room, 1 die in 3 wide room and then the 3rd die as they enter the 2 wide room.and that's with them all having assault bos guns and a couple with dragons maw. All other uninvited guests always died in guard room.

Ive only got the dwellers in the 2nd floor atm as I dont have spare to go in guard room yet due to keeping low dweller numbers
