A new update is now available for Fortnite, bringing a lot more content to both Battle Royale and Save the World. Along with the Sniper Shootout limited-time event, Epic has added an entirely new weapon to Battle Royale and reintroduced one that was temporarily removed from the mode.

Following the update, the Boogie Bomb has returned to Battle Royale. The weapon was disabled earlier this month due to an exploit that allowed players to bomb themselves and effectively pick up an unlimited amount of items. That issue has since been resolved, and players can now find it again in treasure chests and supply drops.
