Borderlands 4 Weekly Update: Sludgemaw Boss, The Falling Wall Mission, and Maurice's Black Market Move (September 24)
Gearbox Software and 2K pushed a new server-side weekly refresh for Borderlands 4 on September 24, 2026, across PC, PlayStation, and Xbox. The update swaps in a new Big Encore boss, replaces the Weekly Wildcard mission with a fresh modifier set and a guaranteed legendary drop, and relocates Maurice’s Black Market vending machine with a refreshed per-account inventory.
Sludgemaw Replaces the Previous Big Encore Boss
This week’s featured Big Encore target is Sludgemaw, which Gearbox describes as a tougher variant of an existing boss paired with an even more rewarding loot pool. Big Encore bosses rotate weekly and are built to give a quick, high-value target for players chasing legendary gear without grinding a full main-story boss fight. Vault Hunters looking to gear up fast should prioritize Sludgemaw this week before the rotation moves to a different target next Thursday.
The Falling Wall Wildcard Guarantees a Legendary Plasma Coil
The Weekly Wildcard mission has also changed, with The Falling Wall taking over from last week’s rotation. The mission runs with three stacked modifiers: Cold Hearted, Elemental Eater, and Armored, which push enemies toward elemental resistance and armor-plated toughness. Clearing The Falling Wall guarantees a Legendary Plasma Coil Maliwan SMG drop, making it one of the most reliably farmable legendary weapons available this week. Because Wildcard missions reset with the weekly update, players have until the next Thursday refresh to complete runs and bank multiple Plasma Coil rolls.
Maurice's Black Market Has Moved (Again) With New Stock
Maurice’s Black Market vending machine relocates every week, and for the September 24 update it’s sitting in the Carcadia Burn region, Tonnage Peel province, at Site Unseen \xe2\x80\x94 reachable by teleporting to the Site Unseen Order Silo, gliding roughly 210 meters east toward a Communications Balloon, and continuing into a small building in Rustspires. Inventory is per-account, so the legendary weapons and gear on offer differ from player to player, and the vendor restocks periodically rather than showing the same items to everyone. Stocking up on in-game currency ahead of a shopping run is easy with a Steam Wallet Code (US), a PSN Gift Card (US), or an Xbox Live Gift Card (US), depending on your platform.
Together, the Sludgemaw encounter, The Falling Wall’s guaranteed Plasma Coil, and a freshly stocked Black Market give players several fast paths to legendary gear this week. Since all three elements reset at the same time, prioritizing them early is the surest way to bank the item before Gearbox rotates in a new boss, mission, and vendor location next Thursday.
