You should also make sure to keep some backup higher-damage weapons handy to equip any new dwellers. Only salvage or sell low-damage weapons when you've equipped all of your dwellers. These weapons can help prepare your dwellers for vault incidents and attacks. I plan to make 4x 3-wide radiorooms to get 75+24 of happiness. I was going to make my 3rd floor a 3/2/3 of radio rooms, waste of space that Id only need one Its really up to you.

You may be tempted to scrap and sell weapons that your explorers aren't using, but you'll find better use out of them by equipping your vault dwellers. Happiness stacks, each room of size 3 provides up to 6 of happiness with 6 dwellers inside (no charisma and upgrades are needed). Use Spare Weapons to Equip All of Your Dwellers You should also make sure that you have enough dwellers to utilize these extra rooms, otherwise they're a waste. If your empty rooms are separated from the rest of your Vault and, ideally, from each other, incidents starting from these rooms will not last long, and will. Rather focus on expanding when you have enough electricity capacity.

Don't Expand Your Vault Too QuicklyĮach new room in your vault consumes extra electricity, so you don't want to needlessly add rooms that you're unable to use just because you've unlocked them. To keep everything aligned, leave room for future expansions and build downwards instead of sideways if you need to add a new type of room.
