The Mycopunk Voltaic Grenade is the go-to crowd-control throwable for squads that want to delete tightly packed mobs without wasting primary ammo, and understanding how its chain lightning actually scales separates a decent throw from a screen-clearing payoff. The grenade was renamed at 1.0 — it used to be called the Shock Grenade — and the new Voltaic name now sits alongside the renamed Caustic Grenade (formerly Acid Grenade) and the newer 1.0 Snowball Grenade as one of three confirmed throwables in the HUB. This guide breaks down chain behavior, the targets that get zapped hardest, and the best weapon pairings for an electrified build.
What the Voltaic Grenade Actually Does in Combat
The Voltaic Grenade is an elemental throwable that applies the shock status on detonation, and unlike a flat-damage burst, the shock arc ripples between nearby targets for a short window. That chain behavior is the reason it dominates against clustered fodder: one well-placed throw can tag four to six grunts in the same pull before the effect fades. Because Mycopunk launched 1.0 on October 20, 2026, the developer has not published a closed list of elements, but the confirmed roster includes cryo, plasma, acid, rot, blood, shock, bees, and water — and the Voltaic Grenade is the dedicated delivery vehicle for the shock effect.
The practical takeaway is that you treat the Voltaic like a primer, not a finisher. A throw that lands in the middle of a pack applies shock to everything in radius, and the lingering arc damage keeps ticking while your squad swaps to weapons that scale off the shocked status. A flat-burst weapon like the Lead Flinger or the G6 Streetsweeper will not benefit much from a tagged enemy, but weapons and upgrades that interact with elemental status will.
Chain Range, Status Duration, and How the Arc Decides Its Next Target
The Voltaic's chain arc has a fixed jump range that the developer has not published numerically — as of the October 2026 launch, Pigeons at Play has not disclosed a meter count for the arc distance. The community rule of thumb (reported by players in early 1.0 sessions) is that the arc prefers the nearest unshielded target, which means throwing into a tight cluster is far more effective than throwing at a single straggler. If the first target dies mid-arc, the chain reattempts to the next nearest enemy in range.
| Voltaic Grenade Behavior | Confirmed Status | What Players Report |
|---|---|---|
| Element delivered | Shock | Shock status applied on detonation |
| Chain mechanic | Yes — arc jumps to nearby targets | Jump count not officially published |
| Best target profile | Clustered unshielded mobs | Strong against Brutes, Rocket Grunts |
| Weak target profile | Lone heavy with a shell | Chain cannot reach if no neighbor exists |
| Cooldown behavior | Standard grenade cooldown | Exact seconds not published |
| Rename history | Was Shock Grenade pre-1.0 | Now called Voltaic Grenade |
The arc is also the reason solo players should pack two grenades. In a four-player squad, someone else will usually pull a second cluster for the chain to bounce into; in solo play, you have to create that cluster yourself with positioning or a secondary AoE weapon. If you only carry one and whiff the first throw, the rest of the mission is back to plain ballistics.
How Shock Status Interacts With Weapons and Upgrades
Shock is a confirmed element in the developer's partial list, which means it interacts with upgrades that scale on elemental chance or elemental damage. The exact formulas for how elemental chance and elemental damage scale have been covered in detail elsewhere, but the practical point is that any upgrade or weapon roll that boosts shock application turns the Voltaic from a one-off throw into a sustained pressure layer. If you slot an upgrade that extends status duration, the chain arc benefits because the arc only continues as long as at least one target remains shocked.
A few verified upgrade names from the developer's published list interact with shock-adjacent behavior. Storm's Eye is the official Shocklance upgrade announced in 1.9.8, and Stormcloud Accumulator and Charging Port are both confirmed upgrade names that lean into the shock/energy family. Slotting any of these on a secondary weapon while running a Voltaic Grenade in your throwable slot gives you a build that applies shock from two sources at once.
Comparing the Three Grenades Available at 1.0
Three grenades are confirmed in the 1.0 HUB: the Voltaic Grenade, the Caustic Grenade, and the Snowball Grenade. Each one delivers a different element and each one rewards a different squad role, so choosing the right throwable starts with knowing what the other two grenades actually do.
The Caustic Grenade (formerly the Acid Grenade, renamed at 1.0) applies the acid element on detonation. Acid into rot is the slow-burn pressure layer the developer's combat design rewards — acid softens a target and rot detonates the softened target for a chunky bonus. That is the loadout for players who want a quiet, sustained damage-over-time profile rather than a flashy chain-lightning moment.
The Snowball Grenade is the 1.0 newcomer, unlocked from the X11-B high-difficulty region. The developer has only published one specific behavior for it: a favorite upgrade lets you "roll it down a hill to gain size like a cartoon." The full upgrade list is unpublished because the developer said they do not want to spoil it. The Snowball delivers the cryo element, which means it freezes targets in place, and stacking cryo sources (grenade + weapon + perk) is the path to Permafrost Wave and the Ice Cube upgrade lines.
| Grenade | Element Delivered | Confirmed Rename | Unlock Source | Best Squad Role |
|---|---|---|---|---|
| Voltaic Grenade | Shock | Was Shock Grenade pre-1.0 | Standard grenade unlocks | Crowd control / arc primer |
| Caustic Grenade | Acid | Was Acid Grenade pre-1.0 | Standard grenade unlocks | Slow-burn pressure / rot setup |
| Snowball Grenade | Cryo | New at 1.0 | Unlocked from X11-B | Hard control / shatter setup |
A squad that runs one of each — a Voltaic thrower, a Caustic thrower, and a Snowball thrower — can layer every confirmed element onto a single pull, which is the cleanest way to test status interactions on a tough Amalgamation or Abomination. The Grenade Upgrades and Element Interactions section of our upgrade-farming guide covers this layering in more detail, including how to spend Antimass on the right status-pairing upgrades.
Weapon Pairings That Make the Voltaic Grenade Sing
Pairing the Voltaic Grenade with the right primary weapon is the difference between a grenade that buys you two seconds of arc damage and a grenade that powers an entire build. The pairing logic is simple: you want a weapon that either benefits from shocked targets or a weapon that adds more shock to keep the arc going.
Pairing With the Shocklance
The Shocklance is the obvious pairing because both the weapon and the grenade are shock-delivery systems, and stacking shock sources extends the arc's effective duration. The Shocklance itself unlocks via the Overtime Assignment, and its official upgrade Storm's Eye (announced 1.9.8) leans fully into the shock identity. If you throw a Voltaic into a pack and follow up with a charged Shocklance beam, every chained target eats the beam as well, which is a clean way to delete Brutes and Pummelers at close range.
If you want the cleanest pairing path, run a Voltaic Grenade in the throwable slot, the Shocklance in the primary, and slot the Stormcloud Accumulator or Charging Port upgrade so the beam's energy economy keeps up with the grenade's chain window. That build wants you in the middle of the cluster, not at the edge, because both the arc and the beam reward proximity.
Pairing With AoE Primaries Like the Lead Flinger and the Cycler
If you prefer raw crowd-clear, pair the Voltaic with an AoE primary like the Lead Flinger or the Cycler. The Cycler in particular is built around a tight, fast-firing cone that rewards you for being inside a crowd, and a Voltaic throw that primes every grunt in range gives the Cycler a status-tagged target list to chew through. The Lead Flinger is a heavier option — it dumps more damage per shot at the cost of fire rate, so a single Voltaic throw followed by three or four Lead Flinger shots into a shocked Brute is a reliable delete on most non-Abomination targets.
| Primary Weapon | Synergy With Voltaic | Recommended Range | Why It Works |
|---|---|---|---|
| Shocklance | High | Close to mid | Stacks shock sources, beam hits chained targets |
| Cycler | High | Close | AoE cone benefits from primed cluster |
| Lead Flinger | Medium-high | Mid | Burst damage into shocked target deletes it |
| G6 Streetsweeper | Medium | Mid | Clean follow-up fire once arc starts |
| DMLR | Medium | Mid-long | Sustained pressure once status is applied |
For a more conservative pairing, the G6 Streetsweeper or the DMLR is a safer mid-range option when the squad is not yet in close. The Voltaic throws first, the squad closes in, and the Streetsweeper or DMLR finishes off whatever the chain did not kill. That pairing works for players who do not want to commit to a melee-range identity.
Pairing With the Diffraction Driver and Other 1.0 Weapons
The Diffraction Driver is a 1.0 ion scattergun that fires a short-range cone by default and, when you hold alt-fire, spins up a halo that tightens the cone and extends its range. It unlocks at level 10. The Driver is a strong Voltaic partner because both the spin-up halo and the arc reward close-range aggression, and the Driver's ion identity stacks with shock status for the brief window the arc is active.
If you have already unlocked the Diffraction Driver, the standard 1.0 weapon progression — covered in our Mycopunk weapons list — already places the Driver around the level-10 unlock window. Treat the Voltaic as a primer for Driver shots: throw first, watch the arc tag the cluster, then spin the halo up and sweep.
How to Get the Globbler and the Carver (and Why They Matter Here)
The Globbler and the Carver are both named weapons in the developer's confirmed 1.0 weapon list, and they each have a reputation as build-defining primaries. If you are building a shock- or status-focused loadout around the Voltaic Grenade, the Globbler and the Carver are worth chasing because they reward the same close-range, high-pressure playstyle the grenade asks for.
The Globbler is named in the official weapons list and has a confirmed upgrade — Globulous Siphon — that pulls ammunition or resources from tagged targets. The Carver is a heavy-hitting close-range weapon that benefits from the Voltaic's arc in the same way the Shocklance does: a primed cluster feeds a single devastating swing into a chained group of enemies.
Globbler: Confirmed Facts and Acquisition Path
The Globbler is on the developer's confirmed 1.0 weapon list, and the only confirmed upgrade name is Globulous Siphon. The developer has not published a step-by-step unlock path for the Globbler, so as of the October 2026 launch, the acquisition is gated by the same general weapon unlock plumbing the rest of the roster uses: level up your employees, hit the right player level, complete the right mission, or roll the right pattern at the Pattern Infuser. The full list of confirmed weapons and their general unlock families lives in our Mycopunk weapons list guide, which also flags which weapons the developer has explicitly named versus which ones are still referenced only by community testing.
The practical approach for a player who wants the Globbler fast is to focus on weapon XP routes that pay out the most XP per minute. The full breakdown of those routes — including which mission types and which weekly reset windows favor which weapons — is covered in our weapon leveling guide. The short version: do not chase the Globbler at low player level, because you will not have the upgrade slots unlocked to make it worth the grind.
Carver: Confirmed Facts and Acquisition Path
The Carver is also on the developer's confirmed 1.0 weapon list, and like the Globbler, the developer has not published a step-by-step unlock for it. The Carver is widely referenced by players as a close-range heavy, and the official upgrade names in the developer's list that lean into the Carver's identity are few — but the Sawed Off upgrade is a confirmed name that fits the heavy-swing family.
The unlock flow for both the Globbler and the Carver is the same general plumbing: progress through the Armament License, hit the right player level, and check the HUB vendor rotation. The Lost Loot Terminal and the Lottery Larry reroll system are the two HUB-side systems that occasionally surface these named weapons as rewards, and the developer's Codex inventory tab tracks which weapons you have already discovered versus which are still hidden. The full unlock-order discussion lives in our upgrade farming guide.
| Weapon | Confirmed Status | Confirmed Upgrade | Acquisition Approach |
|---|---|---|---|
| Globbler | Confirmed in 1.0 weapon list | Globulous Siphon | General weapon unlock plumbing; no step-by-step path published |
| Carver | Confirmed in 1.0 weapon list | Sawed Off (heavy-swing family) | Armament License progression + HUB reward rotation |
Why These Two Pair With a Voltaic Grenade
The Globbler and the Carver both reward the same playstyle the Voltaic enables: get into a cluster, hit a heavy swing, and use the arc as a primer. The Voltaic's chain arc softens the group, the Globbler's heavy shot deletes the softened target while Globulous Siphon keeps the magazine fed, and the Carver's close-range damage is uncontested when a primed cluster is standing still. None of these mechanics are confirmed numerically by the developer — as of the October 2026 launch, the published combat numbers are limited — but the type-level identity of all three tools points at the same playstyle.
Voltaic Grenade Build Recommendations by Mission Type
Different mission types stress different parts of a loadout, and the Voltaic Grenade is a strong default against most of them. The confirmed mission types in Mycopunk's 1.0 roster include Incursion (unlocks at player level 13), Ouroboros (the roguelike mode with a 13-room short variant called Ouroboros Blitz), Escalation, Oxythane Breach, Paid Time Off, Prized Possession, Saxonite Transport, Planetary Defense, Population Control, Ground Zero, Amalgamation Hunt, and Abomination Assault. Each one asks a different question of your throwable.
For tight Amalgamation Hunt or Abomination Assault pulls, the Voltaic is the cleanest opening move because the Amalgamation spawns a 30-second timer once it is active, and you want every second of that timer to be spent inside a primed cluster. Throw first, swap to the Shocklance or the Lead Flinger, and burn the timer down before it expires. The Oxythane Breach and the mid-tier Escalations like Regulated Rampage and Population Control stress enemy density, and the Voltaic's chain arc is the most reliable crowd-control answer the developer has shipped.
The two mission types where the Voltaic is the wrong call are the longer single-target grind — the Planetary Defense phase and the Saxonite Transport escort. Those missions reward sustained single-target damage, which is the Caustic Grenade's slow-burn rot payoff and the Snowball Grenade's hard freeze. Run a Caustic or a Snowball on those missions and keep the Voltaic in the loadout swap.
| Mission Type | Voltaic Viability | Recommended Throwable Swap |
|---|---|---|
| Incursion | High | Keep Voltaic |
| Ouroboros / Ouroboros Blitz | High | Keep Voltaic |
| Amalgamation Hunt | High | Keep Voltaic |
| Abomination Assault | High | Keep Voltaic |
| Oxythane Breach | High | Keep Voltaic |
| Escalation (general) | High | Keep Voltaic |
| Population Control | High | Keep Voltaic |
| Planetary Defense | Medium | Swap to Caustic for sustained DoT |
| Saxonite Transport | Medium | Swap to Caustic for slow burn |
| X11-B (high difficulty) | High | Keep Voltaic, pair with Snowball |
A Practical Voltaic-Centered Build to Try First
If you want a beginner-friendly Voltaic-centered build that uses only confirmed weapon and upgrade names, run this loadout: Voltaic Grenade in the throwable slot, the Shocklance as primary, the G6 Streetsweeper or the DMLR as secondary, and slot Storm's Eye on the Shocklance plus Stormcloud Accumulator or Charging Port on the secondary. The Storm's Eye + Voltaic opening should be enough to delete the first cluster of any Incursion or Escalation pull, and the Streetsweeper covers the long-range cleanup.
This build works in solo play because the Shocklance is self-sufficient at close range, and it works in four-player co-op because the arc bounces between any targets you prime. If you want to push the build further into Exotic or Exotic+ territory, the Pattern Infuser system lets you spend Antimass Substrate on pattern rolls that boost shock chance and shock damage on the Shocklance, which compounds the Voltaic's chain window.
Frequently Asked Questions
What does the Mycopunk Voltaic Grenade actually do?
The Voltaic Grenade is a shock-delivery throwable that applies the shock status on detonation and chains damage between nearby targets for a short window. It was renamed from Shock Grenade at the 1.0 launch. The chain arc prefers the nearest unshielded target, so throwing into a tight cluster gets the best payoff, and the developer has not published a meter count for the chain range as of October 2026.
Was the Shock Grenade renamed to the Voltaic Grenade?
Yes. At the 1.0 launch on October 20, 2026, the developer renamed the Shock Grenade to the Voltaic Grenade and the Acid Grenade to the Caustic Grenade. The old names no longer appear on the in-game grenade list. The Voltaic is the same shock element delivery tool, just under the new name, and the Explosive Bullets upgrade on the Accelerator was also renamed to Combustive Rounds at the same time.
How do I get the Globbler and the Carver in Mycopunk?
The developer has not published step-by-step unlock paths for the Globbler or the Carver. Both weapons are on the confirmed 1.0 weapon roster, and the typical unlock plumbing applies: level up your employees, progress your player level, and check the HUB reward rotation at the Lost Loot Terminal. The Globbler's only confirmed upgrade is Globulous Siphon, and the Carver fits the heavy-swing family that includes the Sawed Off upgrade. Treat the HUB reward rotation as your best bet and the Pattern Infuser as your upgrade-side path.
Is the Voltaic Grenade better than the Caustic or the Snowball?
It depends on the squad role. The Voltaic is the strongest crowd-control and chain-damage option against clustered mobs; the Caustic is the slow-burn pressure layer that pairs with rot for sustained damage-over-time; the Snowball is the hard-control option that freezes and shatters. For a four-player squad running one of each, the Voltaic is the cleanest opening throw. For solo play, the Caustic's DoT profile is more forgiving because it does not require a cluster to pay off.
Does the Voltaic Grenade stack with the Shocklance?
Yes, and that is the cleanest pairing in the game. Both the grenade and the Shocklance deliver shock, and stacking the two shock sources extends the chain arc's effective duration because the arc continues as long as at least one target remains shocked. The Shocklance's Storm's Eye upgrade (announced 1.9.8) leans fully into the shock identity, and slotting Stormcloud Accumulator or Charging Port keeps the beam's energy economy sustainable across the grenade's chain window.
