If you want to farm legendary gear in seconds, duplicate your best items, and kill bosses with one shot, this guide is for you.
Here are over 20+ glitches that still work after the latest update to power up your Borderlands 4 game.
1) Duplication glitch (bank dupe)
Join another player’s game. Have the host or other players cause lag by quickly opening and closing their bank or dropping lots of items. While the game is lagging, quickly take an item out of your own bank. A copy of that item will appear in the bank for the other players.
This works best with only two players and a lot of lag. The person hosting the game usually can’t duplicate items this way.
2) Songbird damage stacking
Farm Songbird from Rock & Roller in Trinket Crevasse Abandoned Mine (post-campaign).
Equip only two guns, empty the Songbird, then weapon swap twice during the auto-reload animation; each perfect swap stacks damage and can lead to near-instant boss kills after a few minutes.
3) Anarchy sticky-mode swap nukes bosses
- Anarchy drops from Radix vault boss.
- Fire Torgue stickies into a target but do not empty the magazine; repeatedly switch between normal and alt fire to detonate/stack in a bugged way that melts bosses.
4) Vladof SMG projectile stacking (Flamethrower + Bullet Holes)
- Needs a Vladof SMG with Flamethrower alt and a Vladof enhancement with Bullet Holes.
- Hold fire in main mode and spam alt-mode toggling; projectiles accumulate so each shot fires multiple rounds, scaling into absurd DPS after ~5 minutes.
5) Birt’s Bees projectile stacking (Flamethrower + Bullet Holes)
- Same method as the Vladof SMG: hold main fire and spam alt-mode; the “bees” stack into hundreds or thousands per shot over time.
- Results in instant boss wipes once stacks are high enough.
6) Birt’s Bees taser swap (sticky magazine required)
- Look for Birt’s Bees with Taser alt-fire and Torgue sticky magazine that explodes on reload/mode switch.
- Dump most of the clip into the boss, swap to Taser and back to transfer damage type; versions with 1-shot Taser alt are even stronger.
7) Birt’s Bees flamethrower + sticky “god roll” (ignores immune phases)
- The most broken roll: Flamethrower alt + sticky gyro jets that explode on reload or mode switch on the same gun.
- Fire most of the stickies, swap to flamethrower and back to main; annihilates bosses and bypasses immune phases like Soul and Bio-Bulkhead. No stacking required once you have this roll.
8) Any gun with flamethrower + sticky combo
- The flamethrower + sticky synergy isn’t limited to Birt’s Bees; even a low-level green with both traits can insta-kill bosses using the same swap method.
- Fire most of the mag, swap to flamethrower and back to trigger the bugged explosion burst.
9) Golden God shotgun overheat stack
- Drops from Soul; perk “Rage” grows damage as the gun overheats.
- Overheat to ~25 “shots fired” in overheat state, then slowly swap to your other gun and back to “bank” the overheated damage; repeat to stack indefinitely, massively increasing base shots at the cost of ammo. Multi-loader secondary (AR/SMG/Pistol ammo) helps sustain.
10) Golden God ammo economy trick
- After stacking overheated damage, a quick double-tap swap at the ~25 mark can reduce effective ammo per shot down to ~2 while retaining huge damage.
- Combine with infinite ammo exploit for pure chaos.
11) No-reload infinite ammo exploit (Order + Free Charger)
- Requires: an Order weapon with Ripper-licensed magazine (charge-to-fire override) and an Order enhancement with Free Charger (30% chance next shot costs zero at max charge).
- Fire and reload until zero ammo cost procs; during the window, quickly swap to another weapon to grant that gun infinite ammo and no reloads, including alt-fires. Persists until you unequip the source parts or reload to main menu.
12) Maurice’s Black Market no-cooldown reroll
- At Maurice’s machine, if the item isn’t a perfect roll, do not exit the UI. Quit the game straight from inside the machine (console dashboard or Alt+F4 on PC).
- Reloading the game removes cooldown and changes rolls immediately, letting you brute-force rolls.
13) Splashzone co-op farm (loot every ~3 seconds)
- One player spams the reset at Moxxi’s Encore while the killer stands on a specific ledge inside Splashzone and jumps to repeatedly spawn/kill the boss.
- Use any of the broken weapons above for instant kills; loot stacks rapidly.
14) Axemaul co-op farm (every ~4 seconds)
- In the Toil of Spoils Abandoned Mine, place one player at Encore and the killer at the portal room edge; walk backward/forward to retrigger the spawn loop.
- Axemaul drops “The Bot” shotgun; perfect for gearing fast.
15) Directive-0 co-op farm (every ~7 seconds)
- Kill once, then in the exit room, walk up to a floor line and dodge backward while the partner spams Encore; timing locks in easily with practice.
- Found in an Order bunker; repeat for fast legendary flow.
16) Sludgemaw co-op farm (every ~6 seconds)
- Unlock via two side quests (Null and Void, then All Charged Up), then run the co-op reset loop from the exit grappling spot to drop back in and re-kill.
- Source for Birt’s Bees—the centerpiece of multiple broken builds.
17) Driller Hole co-op farm (every ~10 seconds)
- One player at Encore; killer stands in the first drop-in room’s far-left corner and double-jumps to give the resetter a consistent window.
- Sprint in, nuke boss, return to the corner, and repeat.
18) Core Observer co-op farm (every ~5 seconds)
- In Black Lime Bunker (Order bunker unlocked mid-campaign), stand by the exit door near the portal while partner spams resets; step in to trigger spawn, step out to loop.
- Very low movement time between cycles means fast loot snowballs.
19) Leader Willem co-op farm (every ~6 seconds)
- Unlock chain: Enter the Elect I, Enter the Elect II, Cancel Divided, A Traitor Within, The Mole’s Gambit; then farm him by standing at the small entry room and micro-stepping in/out while your partner resets.
- Great with Songbird or Bees exploits due to long sightlines.
20) Fractis “noisy cricket” perch farm (every ~2 seconds)
- In the Cruel Craft Order bunker, use the Noisy Cricket’s recoil to rocket-jump across lips, pipes, and wall fittings to a precise perch; your partner spams Encore while you tap-jump to trigger spawns and one-tap with a glitched Songbird.
- Needs a strong shield (e.g., big Turtle) to survive recoil damage during setup and careful positioning to avoid invisible wall pushes.
21) Radix vault boss co-op farm (every ~7 seconds)
- In Carciaburn’s Primordial Garden of Erratics vault, mark the exact pixel spot on the arena floor with a dropped item; when your partner sees Encore flicker, you’ve found it; stand on it to auto-trigger fast respawns.
- Excellent for class items and quick legendary churn.
22) Origo vault boss co-op farm (every ~7 seconds)
- Similar to Radix: identify and mark the precise tile where Encore flickers, but beware Origo’s dive-bomb knocks—your marker helps you realign quickly between kills.
- Keep the resetter spamming continuously; your job is just to reset your footing and delete the boss.
23) Solo Ripper Drill Site boss-only loop
- Unlock two sites: Source Clench Ripper Drill Site (and its nearby fast travel) and Old Scrape/Old Scrap Ripper Drill Site (and silo travel). Clear each site at least once so they’re on the map.
- Run Site A normally to the bosses and kill them; do NOT hit Moxxi’s Encore. Fast travel to Site B, reset and clear to bosses, then again do NOT Encore. Now bounce back to Site A and simply run straight in—bosses spawn instantly without waves; repeat between the two sites for five bosses in a rotation.
24) Crit Knife synergy setups
- The Crit throwing knife is a world drop that supercharges specific weapon exploits; with the right combos, it can one-tap bosses even without skill tree investment.
- Pair with Songbird stacks or Bees sticky/flamethrower swaps for ludicrous burst windows.
Recommended combos
- Bees flamethrower+sticky “god roll” + Infinite Ammo exploit: no stack time, instant boss wipes, bypasses immunities, and infinite alt-fire uptime.
- Golden God overheat stacks + Infinite Ammo: sky-high sustained damage with minimal ammo friction after the double-tap economy trick.
- Songbird stacks + Fractis/Radix/Origo reset spots: ultra-fast co-op runs where travel time is the bottleneck, not damage.
Final word
No matter your style—every trick in this guide is confirmed to work right now.
Try them soon, before the developers patch them! For the biggest power boost, first target the Birt’s Bees, Songbird, and Order/Free Charger weapon combo.
Once you’re powerful, use the specific co-op and solo farming methods we’ve listed to get endless legendary loot.
