What to know

  • The jamming device is destroyed using a ground slam maneuver, not regular attacks.
  • Players must grapple with a platform above the device before performing the ground slam.
  • The ground slam requires double jumping and holding the slam button (Ctrl, Circle, or B).
  • This action is part of the Unpaid Tab main mission in Borderlands 4.

In Borderlands 4, destroying the jamming device is a key objective during the Unpaid Tab quest. Unlike normal combat, you cannot destroy this device by shooting or melee attacks. Instead, you must utilize a specific movement skill: the ground slam.

How to destroy the jamming device in the Unpaid Tab quest

Your first task is to pull a highlighted handle on the DAHL machine to hack the jamming device. After this, proceed to the stairs on the right side and find a grapple point on the south wall behind the machine. Use your grapple hook to climb up to the platform above the device.

Once on the platform, look for a highlighted circle on top of the jamming device. To destroy it, stand above the circle and perform a ground slam.

Platform How to perform ground slam (typical control)
PC Double jump, hold Ctrl while falling to ground-slam.
PlayStation Double jump, hold Circle to ground-slam.
Xbox Double jump, hold B to ground-slam.

Regular attacks like shooting or melee do not damage the device, so mastering the ground slam here is essential.

Additional mission details: saving Quent

Following the destruction of the jamming device, you have the option to save an NPC named Quent. This requires pulling five levers around the machine and destroying three pipes on the ceiling within 60 seconds. The choice to save Quent does not affect mission rewards but is recommended for narrative reasons.
