Fortnite is getting into the holiday spirit. Starting today, its holiday-themed event for the PvE Save the World mode is now live, adding a whole bunch of new activities and items to try out. It's part of a bigger update that also includes some changes and additions for the Battle Royale mode.

Survive the Holidays is highlighted by a new questline that tasks you with bringing "the holiday spirit to everyone in the husk-ridden world," according to developer Epic's patch notes. You'll get a bunch of Snowflake tickets for participating in the event, which can be used to buy special items like Holiday Survival Llamas.
