Lunchboxes | Exploration, weapons and outfits Fallout Shelter Guide

You can find very good dwellers in lunchboxes.

The best prize you can win for achieving your objectives are lunchboxes containing cards with caps, weapons, outfits or new dwellers. You will receive such boxes relatively rarely so it is advised to choose these tasks that let you win one of them, even though they're more time-consuming than other ones. When you achieve the objective you can open the lunchbox (use the Pip Boy). Caps will appear on your account immediately as well as weapon or outfit in warehouse, and gained dweller will be waiting at the front door until you let him in.

Lunchboxes can also be bought in the shop menu

Another way to get lunchboxes is to buy them. You can do it in shop menu, after using a Pip Boy.
