Complete Borderlands 4 Mob Justice Mission Walkthrough

This walkthrough will guide you through each step of the Mob Justice mission, helping you navigate challenges and overcome enemies efficiently.

Go to Lictor's Black Site

1

Talk to the Boss' hologram in his office at The Pit. Afterwards, take the data drive from the console nearby. This drive contains crucial information you'll need for the mission.

2

Follow the marked location on your map to reach Vile Lictor's black site. The location is well-guarded, so be prepared for resistance as you approach.

3

At Lictor's Black Site, look for the red-lit entrance. Once inside, you'll find vending machines (perfect for restocking ammo and health). Drop down into the hole nearby to proceed deeper into the facility.

You'll encounter a locked door mechanism requiring a special device. Return to where you landed from the drop and look for a gap leading to the floor beneath. Use your grappling hook to retrieve the device stuck to the wall, then insert it into the machine to unlock the door.

In the newly accessible room, insert the data drive into the console. Interact with the console to have ECHO halt the download process. Once completed, remember to retrieve your drive before leaving.

6

From the entry point, head straight until you see more vending machines. Look for a ledge with a yellow marker that you can climb. At the top, you'll find a ventilation shaft—crawl through it to access another section of the facility.

After clearing the regular guards, more powerful Vile enemies will appear. Work together with Bruce to defeat these enhanced foes.
