Learn how to complete Plan Z in Borderlands 4 by lifting the Timekeeper’s lockdown and storming Ascension Tower.
‘Plan Z’ is the 19th main mission in Borderlands 4, and it picks up following the Timekeeper’s manipulation in ‘Means of Ascent.’ With no hesitation left about dethroning the Timekeeper after he kills Zadra, the Vault Hunters set out for Ascension Tower, unleashing their fury across Dominion City. The mission is relatively straightforward but throws large waves of high-level enemies at you, rewarding smart play. It is also known to contain a game-breaking bug discussed at the end.

Reach the Data Dump
Pick up Zadra’s ECHO log and wait for the Order forces to cut through the shed wall. Following Zadra’s posthumous advice, head to the Data Dump Cafe and interact with the computer inside to download the data. Killing the enemies in your way is optional, and you can run past them.
Upload the Command Script
With access to Order databases, you need to find a Ripper encampment to lift the lockdown on the Terminus district. Follow the quest marker through the Fades District until you reach a large barrier saying “Keep Out.” Fight off incoming waves of enemies until Colonel Orsen arrives. Interact with his drop pod to upload the command script. Take cover and hold off the Order reinforcements until the upload is complete.

The upload will take about a minute to complete. Once it does, head through the now-open gate and press the button in the central console to gain access to the Terminus district. Follow the road and turn right past the tunnel. Head down the stairs and stick to the left side, climbing up to the building and reaching the checkpoint at its end.
Run up the plaza and toward Ascension Tower, taking the stairway to the left. Fight through Order forces while scaling the stairs until you reach the triangular pylon. Pick up the pylon and carry it back to the Ascension Chamber’s entrance. Throw it at the power socket at the center of the archway opposite the chamber entrance. Head through the open doorway to the Upper Dominion, completing ‘Plan Z.’ Prepare to face the Timekeeper in the next and final mission, ‘The Timekeeper’s Order.’

Borderlands 4: Plan Z Main Mission Bugs and Possible Fixes
Some players have reported encountering a bug in ‘Plan Z’ that prevents them from accessing the Upper Dominion even after the door opens. This bug is encountered when a player dies during the final phase of the mission and tries to interact with the Ascension Chamber entrance, only to find that they cannot progress. Possible fixes for this bug include:
- Restart the game.
- Throw another pylon at the power socket in the archway.
- Join a co-op session with another player in ‘Plan Z’ and complete the mission. You can then continue playing from the final mission in your own game.
