Save the World, the PvE mode of Fortnite, has been updated to include Dungeons. According to Epic Games, you'll get to fight monsters and dodge traps, as you might expect.

Rumor has it that there is a forbidden area within Hexylvania. They say there are even new Weapons and Heroes to recruit along the way. Magical Keys, a deep and dark labyrinth, golden coins... sounds like it’s time to do some exploring!
