This update will dramatically change Fallout Shelter with a new feature called "crafting" which will allow players to turn their useless "junk" into practical items for use. Junk can be obtained as a fifth item from lunchboxes and it can also be found by Vault Dwellers exploring the wasteland. As part of this new crafting system being introduced in Update 1.4, there will be new rooms for creating weapons and armor, fittingly named the Weapon and Armor Crafting Rooms.
The Barbershop will also be added to the roster of new rooms, giving the player the ability to customize the appearance of each Vault Dweller. The customization options don't stop there, however! Outfits and armors from Fallout 4 will be making their way into Fallout Shelter with this update and they can be obtained from lunchboxes or from the new crafting system.
New pets have also been added, with different cats and dogs coming alongside a brand new type of pet: a parrot! Pets will also give out some new bonuses with this update.
Lastly, the time of day will show up as part of the environment, with day and night cycles now being reflected outside of the Vault.
Update 1.4 is now available as a free download for Fallout Shelter in the Google Play or iOS App Stores.
