Borderlands 4’s July 30 Weekly Rotation Targets Bio-Bulkhead Through August 6

Borderlands 4 has a fresh Weekly Activities rotation running from July 30 through August 6. This week’s schedule features the Bio-Bulkhead as its Big Encore Boss, along with a modifier-heavy Wildcard Mission and another Legendary weapon to chase.

The details come from the official Steam announcement. The activity lineup refreshes each Thursday, giving Vault Hunters a new set of targets and rewards to work through.

What to Expect This Week

Bio-Bulkhead is the main boss encounter for the July 30 rotation. Players looking for a different kind of challenge can take on Hangover Helper, which adds the Chain Master, Quickened, and Shielded modifiers to the mission.

Completing the Wildcard Mission awards T.K’s Wave Jakobs Shotgun, giving this week’s activity a clear gear target for anyone building out a Jakobs-focused loadout or simply hunting for another Legendary drop.

Maurice’s Black Market Vending Machine has also moved for the new rotation. Its location is shared across players, but the items inside can differ from one player’s machine to another. Comparing finds with friends may help track down a particular piece of gear.

Borderlands 4 Weekly Activities: July 30 – August 6

The official activity notes are below.

• Weekly Big Encore Boss: Bio-Bulkhead

• Legendary Gear Reward: T.K’s Wave Jakobs Shotgun
• Maurice’s Black Market Vending Machine: Here’s a visual hint to where Maurice’s Black Market Vending Machine is hidden this week. Remember, while this week’s location is the same for everyone, your vending machine items are different from other players, so ask around to see if someone has the item you’re looking for!
