In the Fault Hunting side mission of Borderlands 4, the Electi enlist your help to investigate dangerous seismic tremors threatening The Burn. You’ll need to track down the source of the activity, battle through waves of enemies, and put a stop to the destruction before what’s left of this fragile region crumbles completely.

How to Start the Fault Hunting Quest
To begin the Fault Hunting side mission in Borderlands 4, speak with Leopold at the Society for Amateur Seismology Enthusiasts.
How to Complete the Fault Hunting Quest
Help the Electi find the source of the growing seismic activity and stop it before it demolishes what’s left of The Burn.
Explore the Cave
First, travel northeast to the cave at The Rumbling Cleft. Once you arrive at the entrance, head inside the cave and keep going deeper until you reach the sealed door. After arriving at this door, you’ll need to defeat all the Creeps.
When the area has been cleared, search the area for two clues:
- ECHO Log on the ground to the left of the sealed door
- Sealed door
Once you’re ready to enter the facility, take the air stream then glide to the ledge to the right of the sealed door.
Crouch through the tight space, and eventually you’ll drop down through a hole in the floor.
Explore the Facility
Follow the path and defeat a group of Creeps just before a faulty door. To open this door, wait for it to open then shoot the green cylinder inside on the right.
Keep following the path until you reach the server room.
Once in the server room, examine the Creep corpses.
Afterward, examine the server console. To get the console some power, examine the three cylinders on the south side of the room.
To direct the power to the server console, you’ll need to grapple the metal wires on the roof until the cylinders are connected with the console.
Hack Into Server Console
Return to the server console and interact with the computer. Once you activate it, Creeps will attack, so clear them out.
Reach Genone
To reach Genone, you must travel all the way to The Yawning Yard in Lopside. Once there, head to the lower part of the western cliff to find another sealed door. Genone will open it for you so head inside!
Confront Genone
Work your way through the facility, defeating the enemies along the way. When you reach the large room, activate the console near the sealed door. Genone decides not to open it for you, so you must direct power to the door yourself. Use your grapple to move the wires so that the door can open.
After the door opens, head on through and continue making your way through the area. In the lab, head up the ladder in the center of the room to reach an area with vending machines just before the boss fight.
Stock up then drop down when you’re ready to take on Genone.
Find Control Room Keycard
After defeating the boss, take the keycard from the giant cylinder in the middle of the room. Use it to access the control room.
Power Down Facility
When you are ready, pull the lever in the control room to power down the facility. Afterward, the mission will complete.
