Borderlands 4: Mob Justice Complete Walkthrough
Starting the Mission
Before you can begin Mob Justice, you must complete the preceding missions: Mob Mentality, Mob Rules, and Angry Mob. Once these are completed, return to The Pit and locate the Boss's hologram in his office. Interacting with him triggers the start of the mission. After a brief conversation, your first objective will appear: retrieve a drive from a nearby console. This drive will ultimately be used to sabotage Lictor's operations in the Black Site, the central location for this mission.
It is important to ensure your character is properly equipped before beginning the mission. Enemies in this mission are more aggressive than in previous Mob quests, and you will encounter multiple elite enemies. Stock up on ammunition, health packs, and any shields or grenade mods that give you an edge in prolonged fights.
Infiltrating Lictor's Black Site
Once you have the drive, follow the on-screen map marker to Lictor's Black Site, located southwest of The Pit. The route to the site is littered with hostile patrols and environmental hazards, so move cautiously. The exterior of the Black Site is marked with red lighting and heavy security. Here, preparation is key. Use cover and aim for weak points in enemy armor to avoid taking excessive damage.
When approaching the entrance, you will notice that the primary doorway is locked. At this point, the mission introduces a small puzzle element. Look around the area for a small, protruding battery device on the wall near the floor. Using your grappling hook, you can retrieve the device and install it into the console next to the door. This action powers the door and grants access to the inner facility. Players occasionally encounter a bug where the device does not appear. If this happens, saving and reloading the game or fast traveling away and returning usually resolves the issue.
Once the door is open, proceed through the facility's hallways while remaining alert for enemy ambushes. Lictor's guards patrol the corridors, and some areas contain traps or explosive hazards. Moving methodically and clearing rooms one by one will prevent being overwhelmed. Enemies in this area often have shields or armor, so using weapons with elemental effects, such as corrosive or shock, is highly recommended. These elements bypass defenses and deal significant damage.
Completing the Drive Objective
The inner facility contains a console where you must insert the drive. Interacting with the console initiates the process of halting the enemy's operations. During this phase, you may be attacked by waves of guards and other Vile enemies. Maintaining mobility and using cover effectively will keep you alive. Once the console sequence completes, make sure to retrieve the drive again, as it will be required in the next phase of the mission. Forgetting to pick up the drive at this stage can prevent progress, so double-check your inventory before moving on.
The Bruce Sequence and Rift Entry
After completing the drive objective, your next destination is Stoneblood Forest, where you will meet an NPC named Bruce. Bruce plays a crucial role in connecting the Boss to a powerful system capable of destabilizing Lictor's operations. Interacting with Bruce triggers a dimensional rift, transporting you inside the inner sections of the Black Site.
Upon entering the rift, you are immediately faced with combat challenges. A combination of elite guards and Vile enemies will attack simultaneously, testing both your reaction time and tactical awareness. Using cover, moving continuously, and managing cooldowns for shields and abilities are essential strategies for surviving this sequence. The rift also introduces verticality in combat, so take advantage of higher ground to avoid being surrounded.
Injecting the Virus
The next objective is to locate a console deep inside the Lictor complex and inject a virus Bruce generated earlier. This action destabilizes the facility and significantly weakens enemy forces. The area leading to the console is guarded by powerful enemies, and combat becomes progressively harder as you approach the final room. A combination of long-range attacks to thin out enemies from a distance and close-quarters bursts to handle remaining threats is the most efficient approach.
Once you successfully inject the virus, resistance decreases, and you can move toward extraction points. At this stage, the mission transitions from heavy combat to navigating through corridors that may contain environmental hazards or traps. Make sure to move cautiously and check for hidden paths that may lead to additional loot or shortcuts.
Returning to The Pit
After injecting the virus and clearing the final enemies, return to The Pit. Both Bruce and Defiant Calder will be waiting to conclude the mission. The Boss reappears via hologram, and you will be prompted to upload him into Bruce's system using the drive. This sequence also triggers a cutscene, highlighting your successful completion of the mission and establishing you as a new influential figure within the Mob hierarchy.
Rewards and Benefits
Completing Mob Justice offers a combination of currency, experience, and loot. Rewards include a substantial amount of in-game cash scaled to your character level, significant experience points to help level up, and Eridium, which is useful for upgrading weapons and equipment. Additionally, the mission rewards a grenade mod of blue to purple rarity, which can be highly effective in both combat and crowd control. Players also receive a cosmetic Vault Hunter head, symbolizing their new status as a leader within The Pit.
The mission's narrative and completion also unlock additional side missions and provide access to new vendors who sell high-level gear and consumables. Engaging with these post-mission opportunities can enhance your character's capabilities and prepare you for upcoming challenges.
Combat Tips and Strategies
Combat in Mob Justice can be intense, especially during waves of elite enemies. Some useful strategies include:
Clearing rooms systematically to avoid being overwhelmed. Leaving enemies alive can prevent progression in certain segments.
Utilizing elemental weapons to bypass shields and armor. Corrosive and shock effects are particularly effective against heavier enemies. You can buy Borderlands 4 Weapons to get them.
Maintaining mobility to avoid being surrounded. Use cover, elevation, and environmental obstacles to your advantage.
Timing shield and ability cooldowns to survive extended engagements, especially during the Bruce escort phase.
Exploiting verticality in combat areas to manage multiple threats simultaneously.
These strategies will not only make encounters more manageable but also increase efficiency in completing objectives without unnecessary retries.
Post-Mission Opportunities
After finishing Mob Justice, check for new missions in The Pit. Completion of this mission often unlocks higher-level challenges, additional narrative content, and rare loot opportunities. Visiting vendors post-mission allows you to spend your accumulated cash and Eridium on upgrades, ensuring your character is well-prepared for future missions. The mission also provides insight into the broader Mob storyline, rewarding players who invest time in exploring side content.
Conclusion
Mob Justice is a pivotal side mission in Borderlands 4 that blends combat, puzzle-solving, and story progression. With careful preparation, attention to environmental cues, and strategic combat, players can successfully navigate Lictor's Black Site, complete the virus injection, and return to The Pit with valuable rewards. Beyond the immediate benefits, the mission enriches the narrative of The Pit and positions your character as a key figure in the Mob hierarchy. By following this walkthrough, players can ensure a smooth and satisfying completion, unlocking further content and maximizing both rewards and story engagement.
