Borderlands 4’s September 24 Weekly Activities Bring Sludgemaw and a Plasma Coil
The Falling Wall carries Cold Hearted, Elemental Eater, and Armored modifiers, while Maurice's Black Market Vending Machine has moved to a new location.

Borderlands 4‘s latest Weekly Activities are live from September 24 through October 1, giving Vault Hunters a new boss to defeat, a modifier-heavy mission to clear, and another Legendary weapon to chase. The rotation follows the September 10-17 rotation, which paired Sidney Pointylegs with the Overwriting a Wrong mission and its San Saba Songbird reward.
The rotation arrived through a server-side update, so players need an internet connection to see the current activities in-game. The latest Steam announcement lists Sludgemaw as the Weekly Big Encore Boss and The Falling Wall as the Weekly Wildcard Mission.
Sludgemaw leads the weekly rotation
Sludgemaw is the main target for this week’s boss activity. Players who have finished the main campaign can find the Weekly Big Encore Boss and Weekly Wildcard Mission through the Map tab in the ECHO menu.
The Falling Wall rewards a Plasma Coil
The Falling Wall comes with the Cold Hearted, Elemental Eater, and Armored modifiers. Completing the mission awards the Plasma Coil Maliwan SMG, giving the Wildcard activity a clear gear target before the rotation changes on October 1.

Maurice’s Black Market Vending Machine has moved
Maurice’s Black Market Vending Machine is hidden in a new location for the week. Its location is the same for everyone, but the items inside can differ from player to player, so comparing finds with friends may help when searching for a particular piece of gear.
