What to Upgrade First in Fallout Shelter
Definitely start by upgrading your water treatment and diner rooms. Keeping your dwellers fed and hydrated is key to keeping them happy and productive. After that, focus on upgrading your power rooms because without power, your other rooms won't function as efficiently. This solid foundation will help your vault thrive!

Power rooms, no question. You'll run outta juice faster than you think and then everyone's sitting in the dark wondering why the food's gone bad. Keep those lights on!
Gotta say, I disagree with the focus on power first. Water and food are life. Without them, your dwellers are just fancy decorations. Upgrade water treatment and diner first, then worry about keeping the lights on.
