2
Borderlands 4 - The Killing Floors

4
Borderlands 4 - Activate Shower
After clearing the area, head inside a room with a glass window and press the highlighted button. Exit to the other side to pull the lever above the entryway. Stand where you are and let the meat cover you. If you are killed after being showered, you have to redo the process.

Objective 3: Find Zadra

# Walkthrough

Following the path, find a vent and crawl into it until you fall into a room with a window. Zadra and Timekeeper will be on the other side of the glass. When Timekeeper disappears, talk to Zadra.
2 In the next area, Zadra will try to unlock the door as you fend off waves of enemies. Be especially careful of the Corrosion enemy and the enemy that turns itself invisible. After Zadra unlocks the door, continue your escape.
3 Clear another room of enemies. Make sure every enemy has been eliminated before taking the elevator with Zadra to the roof.
4 At the roof, gather teleporter parts for Zadra by eliminating enemies. The parts are: 3 Controller Circuits and 1 Transponder Pack. These parts will be dropped randomly so kill as many enemies until they drop them all.
