Lunchboxes

Lunchboxes are premium containers which you can obtain from completing objectives, getting positive evaluation for seven consecutive days, or by buying them using real money. These containers contain resources, caps, Weapons, Outfits, and new Dwellers with higher stats.

If you're lucky, you can even obtain Legendary Dwellers. These powerful Dwellers have their own signature weapon and outfit which you can remove and temporarily give to other dwellers. You'll know if you got a Legendary Dweller or Item if the flashing light before the content is revealed is colored yellow.
