Fallout Shelter has been recalibrated once again, this time with Update 1.4, which is available today completely for free for Android and iOS platforms.
The most important inclusion is the ability to craft items in the new weapon and armor crafting rooms and using junk, which you can find as a free fifth card in lunchboxes. Along with the crafting rooms comes the Barbershop, where you can finally customize what every Dweller looks like.
You'll also find plenty of new outfits and weapons straight from Fallout 4, in addition to new pets like parrots and new dogs and cats. Bethesda says that the these companions will come with "new Pet bonuses" so we'll have to see what that means.
