Fallout Shelter Tips and Tricks

Rare and Legendary Dwellers are the best cards to get out of your starter lunch boxes. Try to create a new vault until you have at least 1 rare and 1 legendary.

Keep your women impregnated. By the way, learn how to make a baby.

Don't use the same guy to impregnate all the women, or else the kids will have the same stats.

Pregnant women and kids cannot fight. Pregnant women can work. Kids do nothing.

The game slows down IMMENSELY after 12 outside Dwellers join your vault. It picks up again once you unlock the Radio Studio.

Breed what you need. The babies usually have a high stat from one of their parents.

Don't expand too fast, or you will find yourself not being able to sustain the new rooms.

Weapons are essential to fight off raiders. Send an armed Dweller to the Vault room before the raiders break in. Once the raiders move to another room, unequip the weapon from him and give it to a Dweller in the new room.

Complete your objectives ASAP. Your objectives consist around 50% of your income, the other half coming from bonus CAPS on resource room completion based on the Luck of the Dwellers in that room.

Get 1-2 Wastelanders with 3+ E and 3+ L. Their will make them stay alive longer and good Luck will give them more item drops.

Having large resource rooms increases them efficiency for each block once combined. (1 large 3 unit room with same Dweller Stats > 3 single unit rooms with same Dweller Stats.) This will also save space and will be easier for your Dwellers to fight raiders in a large room rather than having to move the weapon around 3 small rooms.

Don't sell your gear. A +3 I lab coat is only worth 10 CAPS. Instead equip on Dwellers in the appropriate room.

Common outfits gives 3 bonus points, rare gear give 5 points, legendary gives 6-7 points.

Try to have your resource gathering Dwellers have at least level 2 in the corresponding skill to increase efficiency.

Upgrade units before building more! Building more units will cost more power.

To join units together, they must be the same kind of unit and the same level.

Having a high charisma Dweller in the Radio Studio will attract more Dwellers.

You can increase your Dwellers S.P.E.C.I.A.L stats with the rooms you unlock after the Radio Studio. One room for each skill.

Your Dwellers start becoming irradiated once the water purification supply is too low.

Contain random outbreaks of fire and radroaches ASAP, or they will spread to nearby rooms. This is done by having a Dweller who can fight(non-pregnant adult) in the room. /u/wickedr

Click on the wasteland to bring up your wandering Dwellers. If they are low HP, recall them.

You can have a maximum of 15 stimpaks and 15 rad kits PER BAY/LAB.

The higher the charisma between a couple will lower impregnation time.

Use RUSH up until 40% incident rate.
