Fallout Shelter has been updated with a ton of new quests as well as new quest types including weekly quests, special event and holiday quests. Players can also spend Nuka-Cola Quantum to skip quest altogether.
In a special nod to Fallout 4, Fallout Shelter also has its version of Nuka-World in the form of a special Nuka-World themed mission that will reward a pair of mascots appropriately named Bottle and Cappy.
Lastly, a series of new objectives have been added to give Dwellers a chance to earn additional resources.
