Genone Borderlands 4 Drops, Location and Farming Guide

What to know

Genone is a side boss encountered during the Fault Hunting mission in the Carcadia Burn region.
He features high health regeneration and absorbs fire damage, making elemental strategy crucial.
Reaching him involves solving power-directing puzzles using your grapple hook.
Defeating Genone rewards legendary items like the Oscar Mike assault rifle.

As you dive into Borderlands 4's chaotic world on the planet Kairos, side missions like Fault Hunting offer thrilling detours from the main story. This quest leads you to Genone, a formidable AI-controlled boss lurking in underground facilities, where you'll tackle puzzles, fend off enemies, and claim top-tier loot.

Genone drops (table)

Item name	Type	Notes / why chase it
Oscar Mike	Legendary assault rifle	Dedicated boss drop — high-tier assault rifle sought for unique effects; can be farmed by rematching Genone after Fault Hunting.
Recursive	Legendary ordnance (grenade)	Reported in Genone’s boss loot pool (chance drop); Recursive’s effect: hovers and rains a beam on targets.
Quest rewards	Cash / XP / Eridium / weapon (green→purple) + cosmetic skin	Standard Fault Hunting completion rewards appear in the mission reward table.

Notes on drops: both Oscar Mike and Recursive are chance drops — not guaranteed — and multiple sources confirm Genone’s loot pool includes them, so repeated kills increase your chance.

Genone location in Fault Hunting area: How to reach and find him

Genone is the climax of the Fault Hunting side mission. You can start Fault Hunting by talking to Leopold at the Society for Amateur Seismology Enthusiasts or by accepting the mission after restoring parts of Carcadia (both routes lead to the same objective). The boss arena sits in the Lopside (the Yawning Yard area) — expect to glide down cliffs and enter a sealed facility to trigger the encounter.

Step 1

Accept Fault Hunting from Leopold (Society for Amateur Seismology Enthusiasts) or grab the mission after the Carcadia sequence; follow the objective marker northeast toward the tremor site.

Step 2

Enter the initial cave and use geysers/glide points to reach the upper passages. Kill the creeps that block the pathway.

Step 3

At the server room, locate the server console and the nearby power source. Use the grappling hook points on the ceiling to route power so ECHO-4 can hack the console (defend the hack from waves of enemies).

Step 4

After the console sequence finishes, leave through the south door and follow the map marker to Lopside / The Yawning Yard (the Makeshift Chalet safehouse is a nearby landmark).

Step 5

Glide down the cliff edge in Yawning Yard to find the exterior door — approach it: Genone will open it and you’ll pass through a small facility that mirrors the earlier rooms. Kill synth prototypes and interact with the consoles/flip the switches to proceed.

Step 6

Work the power-routing puzzle again (grappling points on the ceiling) to open the red locked door. Proceed through the contamination chamber and follow the location line up the ladder and through vending corridors until you drop into the boss arena.

Step 7

Fight Genone in the arena; after the fight pick up the blue control-room keycard (it appears behind the machine where Genone emerged) and finish the mission objectives if you want the full quest reward.

How to fight Genone (tactics and counters)

Elemental targeting: Genone’s shield is particularly susceptible to Shock; his armor is best removed with Corrosive attacks. Bring Shock weapons for shield break and Corrosive for prolonged damage to armor.
Adds and arena flow: Genone summons synth minions — clear them quickly or use area-damage ordnance to avoid being overwhelmed. Keep moving and use cover when he uses Shock splash attacks.
Avoid relying on fire-based DPS: community reports note Genone can regenerate a lot of health and sometimes absorbs or reduces fire effectiveness, so Shock/Corrosive is safer.
Second-wind & positioning: know where to grab a Second Wind in the arena (use high ground and the ladder route to reposition); pick up the control-room keycard after the fight to finish mission steps.

How to farm Genone efficiently

Complete Fault Hunting once to unlock the arena.
Use the map to revisit Genone’s arena (you can fast-travel back to Yawning Yard).
If available, use Moxxi’s Encore (Encore Machine / boss-respawn methods) to rematch Genone for repeated loot attempts — that’s the practical way to farm Oscar Mike and Recursive.
Bring Shock + Corrosive builds, clear adds fast, and run repeated quick kills (clear adds → break shield → finish) to maximize runs per hour.

Caveat: community threads show occasional boss bugs (rapid regen or strange elemental absorption). If you suspect a bug, try reloading the area or repeating the encounter later.

Wrapping up: should you farm Genone?

If you want Oscar Mike (a sought legendary assault rifle) or the Recursive ordnance, Genone is a solid target: the encounter is accessible early in Carcadia Burn once you finish Fault Hunting, the arena is repeatable for farming, and his dedicated loot makes the grind worthwhile. Use Shock + Corrosive tactics, clear adds efficiently, and be prepared for occasional boss behavior oddities noted by players.
