How to Unlock the Globbler in Mycopunk (Secret Acid Launcher)

A three-switch secret in Gravity Farms leads to the Scorched Transponder, the hidden Ground Zero mission and Mycopunk's bounciest weapon.

Last updated:

The Globbler is a secret weapon — an acid grenade launcher that fires bouncy globs. To unlock it: find the three-switch bunker in Gravity Farms, grab the Scorched Transponder, activate it from Storage to unlock the hidden Ground Zero mission, complete it, then craft the weapon.

What the Globbler Is

The Globbler is not in the normal unlock flow. It does not come from Armament License progression or mission rewards — it is one of Mycopunk's hidden weapons, sitting in your weapon list with no hint of how to get it. In game terms it is a grenade launcher with a twist: every glob ricochets up to five times before exploding, applies acid, and feeds a meter called the Globblometer that powers several of its upgrades.

Community tier lists rate it at the very top for raw damage potential once built out, so it is worth the hunt. For context on its siblings, see secret weapons and the full weapon list.

Step 1: Start Any Mission in Gravity Farms

Pick any mission in the Gravity Farms region at any threat level — guides recommend the easiest setting, since none of the steps scale with difficulty. Your targets are on the map from the moment you land.

Step 2: Find the Bunker With Three Lights

Near the center of the map sits a bunker-like container with three colored lights on top, one per switch. All three lights start off. Each switch hides behind a breakable door or wall somewhere on the map, and the general layout reported by multiple guides is consistent:

SwitchLandmark to look forHow to open it
OneA large tower with fungus protruding through the topShoot the door panel, flip the switch
TwoA silo beneath the only giant purple mushrooms on the mapBreak the wall, flip the switch
ThreeA tall structure covered in purple goo near the huge domeBreak the side door, flip the switch

Guides disagree on which color light maps to which structure — reports variously describe the colors as yellow/blue/red or magenta/cyan/yellow — so don't burn time matching colors. Just clear all three landmarks and check the bunker lights. Breaking hidden doors like these counts as exploration damage, so any weapon works.

Step 3: Collect the Scorched Transponder

With all three switches active, the bunker opens. Inside on the ground sits the Scorched Transponder, which goes to your Storage tab on the HUB. Abort the mission and head back to the rig — nothing else in this run matters.

Step 4: Activate the Transponder and Find Ground Zero

Back on the HUB, open Storage and interact with the Scorched Transponder. This unlocks the hidden mission Ground Zero, which appears in your mission terminal. Reports differ on which region it lists under — one guide places it in Gravity Farms, another in Titan City — so scan both tabs before assuming the unlock failed.

Bring a squad if you can: Ground Zero has no revives, and in solo a death means restarting the mission from scratch.

Step 5: Complete Ground Zero

The mission sends you after a crashed rocket or ship. Multiple guides describe the same beats: survive the approach, break open the hull, descend through breakable hatches, and pull a lever deep inside. Flicking that lever rewards the Globbler blueprint and its acid resource — one guide also notes a cargo pod drops for extraction.

Step 6: Craft the Globbler

Like any weapon in Mycopunk, the blueprint alone is not the weapon. Return to the rig, gather the listed resources, and craft it. Once crafted it is yours permanently, and its upgrade grid works like every other weapon's.

Its upgrade pool is what turns it from a meme into a monster. Standouts:

UpgradeRarityEffect
Pressure CookerExoticHold the trigger to charge a glob for more damage and explosion size — but dumping all ammo explodes on you
FloodExoticGlobs create a running wave of acid on impact
Globulous SiphonExoticHold reload to consume grenade charge for a massively bigger next glob
TriagonEpicFire three globs in a triangle formation
Glob BalloonsEpicWeaker globs that leave damaging acid puddles
Instant DetonationRareGlobs detonate on first contact instead of bouncing

Note the self-damage theme: several upgrades hurt you, and the Rare "Replicator Resistance" upgrade exists specifically because you will blow yourself up. The Globbler rewards players who like risk — if that's your style, pair it with a loadout from best builds and check how it stacks against the meta in our weapon tier list.

Completing Ground Zero also ticks its achievement, so the trip pays double. And if you'd rather dig up a melee monster instead, the Carver chainsaw hides behind a similar multi-region hunt.

What is the Globbler in Mycopunk?

A secret grenade launcher that fires bouncy acid globs. It is hidden behind a three-switch puzzle in Gravity Farms and the Ground Zero mission, not normal progression.

Where are the three switches for the Globbler?

All three are in Gravity Farms, on any difficulty: a fungus-topped tower, a silo under the giant purple mushrooms, and a goo-covered structure near the big dome. Each hides a switch behind a breakable door or wall.

What does the Scorched Transponder do?

It is the item from the Gravity Farms bunker. Activating it from Storage on the HUB unlocks the hidden Ground Zero mission, which rewards the Globbler blueprint.

Is the Globbler good in Mycopunk?

Yes, once upgraded. Its base form is underwhelming, but Exotic upgrades like Pressure Cooker and Flood push it to the top of community damage tier lists for crowd-heavy fights.

Can you unlock the Globbler solo?

Yes — the switch hunt works solo on any difficulty. Ground Zero is the risky part, because it has no revives; solo deaths restart the mission.
