If one of your dwellers happens to die from a radroach infestation or a raider attack, make sure to revive or remove them quickly – it turns out that working in a room with a dead body makes people really unhappy.

Unsurprisingly, being hurt or irradiated reduces your dwellers’ happiness, so keep them healthy, and failing a rush will reduce their happiness by 10% (but only temporarily).

If you want your dwellers to be even happier, you can boost this further by successfully rushing a room (which adds 10% happiness), having the dweller procreate (50% increase in happiness), or building a Radio Room, which adds 1% happiness for each 10 charisma.

Keeping your dwellers happy isn’t rocket science – assigning them to the right room will boost their base happiness to 75%, so make sure everyone is working where they’re most useful.

While all of your SPECIAL attributes are worthwhile, Luck affects the chance of getting bonus caps from collecting resources, so it’s a good idea to upgrade your Game Room and keep it full at all times.

Be careful about having too many pregnant dwellers – a baby boom can overwhelm your vault and make it impossible for you to recover! Don’t get carried away though – children can’t work, but they do take up resources. Pregnancy is the best way to grow your Vault, so try to match up dwellers with good attributes to create better children.Be aware that SPECIAL attributes are exponentially more difficult to raise with each point, so raise your lowest attributes first. Training is a great way to boost your dwellers’ effectiveness, but it can be time consuming – save time by having multiple dwellers in the same room.Always arm and outfit your dwellers! Radroaches can appear anywhere, so don’t be a casualty!.

Every lunchbox has a chance for a rare or legendary dweller – you might want to consider restarting your vault until one of your free lunchboxes gives you one! Not all dwellers are created equal! The dwellers that arrive at your vault or are born there can have decent SPECIAL, but if you want a really exceptional dweller then you’ll have to find them in lunchboxes.If you’re not sure where your dwellers should go (like if they have multiple high stats), you can drag them over the various rooms in your vault – when you find the best fit for your dweller the outline of the room will turn green. Keeping your dwellers happy is important, and might seem complicated at first, but Fallout Shelter makes it easy for you.
