From Press Release:
A big storm is about to roll through the world of Fortnite! Available on August 29, the “Survive the Storm” update includes an all-new “Survive the Storm” mode, special mutant storms with unique challenges and rewards, new weapons, new heroes, and more!
The threat is only here for a limited time, so players are encouraged to jump in to see if they can survive the storm and earn some exclusive loot!
Survive The Storm Mode
This limited-time mode will test even the most prepared Commander. Gather resources during the day while battling increasingly more difficult threats every night.
Limited-time Storms have modifiers like enraged husks or limited health. Survive these Storms and players can earn some special loot.
Hydraulic Weapon Set
Introducing the hydraulic weapon set. Scavenged from the industrial yards of Plankerton, and rebuilt into husk-destroying machines, these nine high-impact weapons can only be acquired by earning tickets as players complete mutant storms.
Epic’s also added new heroes and defenders along with a host of performance enhancements and brand new art for the Canny Valley Outpost.
