Fortnite v43.10: Buggy boss, new Sprites and Miku arrive

Epic Games released Fortnite v43.10 on November 12, 2026, the first major update of the Treasure Hunters mini season. It adds Buggy from One Piece as a boss, the Cursed Kelper Sprite and a rule that boss weapons now always drop when a boss is eliminated, with more content scheduled for the weekend.

What's new in v43.10?

• Buggy boss: Buggy now appears as a boss on Crossbones Isle. Beating him drops the Special Buggy Ball.
• Guaranteed boss drops: defeating a boss now always drops its weapon.
• Cursed Kelper Sprite: raises the chance of rarer Sprite variants. Carrying a Cursed Sprite makes water deal damage, and a new visual effect shows when the curse is active.
• Exotics in chests: some of the season's Exotic weapons can show up in chests, and Epic has teased a chest that holds all of them.

What's coming this weekend?

• PC players can download High Quality Assets through the Epic Games Launcher instead of streaming them.

• Diagonal drift on the Old School and Quick Builder controller presets is fixed, and Inventory and Map keys can be rebound.

In Reload, Springfield returns with the Donut Storm in both Ranked and Unranked, rotating with Squid Grounds and Surf City. For Creative and UEFN, Epic's pre-release notes listed fixes for the Typhoon Blade, Killswitch Revolvers and the Common Holo Rush SMG, with no new known issues.
