The "Fortnite Runners" update gives us a fresh island, new POIs, a Battle Pass, and a wide range of chaotic items that affect how matches unfold. Among the most valuable additions are Vaults, hidden underground loot rooms that give players access to Rare Chests, Sprite Chests, and Slurp Barrels.
The Vaults are central to fast progression in "Fortnite" Chapter 7 Season 3, especially for players aiming to secure strong early-game loot.
