Borderlands 4’s September 10-17 Weekly Rotation Pairs Sidney Pointylegs With a San Saba Songbird Reward
Overwriting a Wrong carries the Tricky, Quartermaster, and Arms Dealer modifiers, while Maurice's Black Market Vending Machine has moved again.
Borderlands 4‘s Weekly Activities for September 10 through September 17 are live, giving Vault Hunters a new boss, a modifier-heavy mission, and a Legendary pistol to chase. The activities arrived through a server-side update, and players with an internet connection can see the current rotation in-game.
The official Steam announcement lists Sidney Pointylegs as the Weekly Big Encore Boss. The Weekly Wildcard Mission is Overwriting a Wrong, which comes with the Tricky, Quartermaster, and Arms Dealer modifiers. Completing it awards the San Saba Songbird Jakobs Pistol.
Sidney Pointylegs leads the weekly activities
Sidney Pointylegs is the week’s main boss target, giving players a fresh encounter to tackle before the rotation changes on September 17.
Overwriting a Wrong offers a different challenge through its three modifiers. The San Saba Songbird Jakobs Pistol is the mission’s Legendary Gear Reward, making the Wildcard Mission the clearest destination for players hunting this week’s featured weapon.
Maurice’s Black Market machine changes location
Maurice’s Black Market Vending Machine has moved to a new spot for the September 10 rotation. Its location is the same for everyone, but the items inside can differ between players, so comparing finds with friends may help when searching for a particular piece of gear.
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. Both activities remain available through September 17.
