Mycopunk patch notes track the live shape of a 4-player co-op looter shooter that just exited a roughly 15-month Early Access run and shipped its 1.0 on October 20, 2026. Devolver Digital and Pigeons at Play used Early Access to land balance passes, new regions, and the Mycologist employee, so the official update history doubles as a roadmap of what is now in the build. If you want a single place to read what changed, when it changed, and what is rumored to come next, this is it.
The Full Mycopunk Update History From Early Access to 1.0
The mycopunk update history splits neatly into two eras: a long Early Access cycle that ran from July 10, 2025, through October 19, 2026, and a tight 1.0 window that condensed the launch patch, the post-launch Known Issues list, and the developer’s first hotfix into a single day. Most of the player-facing content — regions, employees, weapons, mission types, the Fulfillments system — landed before 1.0, and the launch build is largely a polish and rename pass rather than a content drop.
The pacing matters because community wikis, third-party guides, and roadmap trackers had roughly 24 hours of lead time before this article went out. Per the developer, Expedition Alpha (which unlocks the Mycologist) and The Couch (a 1.0 mini special assignment) shipped alongside the 1.0 build, while the rename pass — Acid Grenade becoming Caustic Grenade and Shock Grenade becoming Voltaic Grenade — caught returning players off guard even though it was telegraphed in pre-launch notes. Tracking the mycopunk 1.0 patch notes alongside the pre-launch cadence is the only way to understand why a build behaves the way it does on day one.
Early Access Milestones (July 2025 – October 2026)
Early Access began on July 10, 2025, and the developer pushed regular mycopunk patch notes for 15 months before promoting the build to 1.0. Below is the publicly confirmed timeline of structural changes that shipped in that window, with the developer’s own framing and the content each milestone unlocked.
| Milestone | Approximate Date | Headline Addition | Key Mechanic / System Introduced |
|---|---|---|---|
| Early Access launch | July 10, 2025 | Core 4-player co-op loop | Gravity Farm and Moldy Tundra regions, HUB dropship, Antimass Substrate, Upgrade Grid |
| The Swamp and the Cranius reveal | Late 2025 | New biome and boss archetype | The Swamp region, Cranius enemy line, HUB rework |
| Ice Floes update | 2026 (pre-1.0) | Cryo element comes online | Ice Floes region, Permafrost Wave, Snowball Grenade teaser |
| Freeze and Fester | 2026 (pre-1.0) | Acid and rot combo layer | Acid → Rot conversion, Blood Explosions, Shock as a universal trigger |
| Ouroboros update | 2026 (pre-1.0) | Roguelike mission type | Ouroboros and Ouroboros Blitz (13-room short variant), Contraband rarity tier |
| Ice Floes expansion | 2026 (pre-1.0) | World-size increase | Photon Disc Grenade, harder enemy modifiers in cold biomes |
| Patch 1.9.5 | Pre-1.0 | Quality-of-life pass | Upgrade Grid readability, Antimass drop tuning, Steam Deck verification |
| Patch 1.9.8 | Pre-1.0 | Balance + named upgrades | Storm’s Eye (Shocklance) named in announcement, weapon scaling passes |
| Patch 1.10.1 | Pre-1.0 | Pre-launch polish | Threat level ceiling explicitly capped at 7; launcher no longer references Threat 8 |
| 1.0 launch | October 20, 2026 | Fifth employee + X11-B | Mycologist unlock, X11-B moon region, Expedition Alpha, The Couch, rename pass |
The biggest pre-1.0 swing was the Ouroboros roguelike mode, which retroactively added a Contraband-only rarity tier and pushed the developer to formalize the Oddity and Broken Frame edge cases. After that, the Ice Floes expansion was the last major content drop before 1.0, and the patches between 1.9.5 and 1.10.1 were almost entirely quality-of-life and balance passes designed to make sure the 1.0 build did not land with the same rough edges the EA build had in summer 2025.
What Shipped in the 1.0 Build
The 1.0 build of October 20, 2026, is the densest single entry in the entire mycopunk patch notes archive. It adds a new region, a new employee, two new mission types, two new weapons, a renamed grenade pair, a renamed Accelerator attachment, and the Fulfillments cosmetic system, all while the developer was still publishing a Known Issues list the same day. Returning players should treat 1.0 as a soft reset for terminology more than for power, because the underlying weapons and regions were already in the build before launch.
| Addition | Type | How It Slots In | Notes for Returning Players |
|---|---|---|---|
| Mycologist | Employee (5th) | Unlocked via Expedition Alpha rescue mission | Kit is Sporelift, Fungal Skewer, and a passive called Infection; full upgrade tree is unpublished |
| X11-B | Region | Moon of New Atlas, high-difficulty, EM storms disable abilities | Room count and enemy list not yet published |
| Expedition Alpha | Mission type | Story-locked rescue that unlocks the Mycologist | First clear is gated by player progression |
| The Couch | Mini special assignment | 1.0-exclusive side activity | Lighter than Incursion or Escalation, designed as a palate cleanser |
| Diffraction Driver | Weapon | Ion scattergun; unlocks at player level 10 | Alt-fire spins up a halo to tighten the cone and extend range |
| Snowball Grenade | Grenade | Cryo grenade unlocked from X11-B | Favourite upgrade lets you roll it down a hill to gain cartoon-physics size |
| Fulfillments | Cosmetic system | Achievement-style unlocks that reward Hats | Full list is unpublished; two specific Fulfillments were broken at launch |
| Caustic Grenade | Rename | Was Acid Grenade | Old name still appears in some UI strings |
| Voltaic Grenade | Rename | Was Shock Grenade | Same; check your grenade wheel after the update |
| Combustive Rounds | Rename | Was Explosive Bullets (Accelerator attachment) | Functionally identical, only the label changed |
| HUB rework | System | Redesigned orbital dropship, new NPCs | Lottery Larry, Roachard Cox, Battery Barry repositioned |
The renames are the single most common source of confusion in the mycopunk 1.0 patch notes, because the old grenade names still float around in community screenshots and old guide videos. Treat the new labels as canonical; if a guide or video says “Acid Grenade,” it almost certainly means Caustic Grenade in the current build.
Balance, Bug Fixes, and Tuning Passes in 1.0
Beyond the headline additions, 1.0 bundled a balance pass that touched weapon scaling, mission modifier tuning, and the Antimass economy. The developer’s own framing in patch note write-ups was that 1.0 was the first time the numbers across the entire build were tuned against a stable target — Early Access builds had been rebalanced in isolation for so long that some weapons were running 30–40% above or below the intended curve.
| System | Change Type | Direction | What Players Feel |
|---|---|---|---|
| Weapon damage scaling | Rebalance | Flattened outliers | Some weapons feel stronger, some feel weaker, but no single gun dominates |
| Antimass drop rates | Tuning | Slight buff at mid-threat missions | Faster Pattern Infusion cycles at Threat 3–5 |
| Saxonite drop rate at Threat 7 | Confirmed value | ~60% per eligible kill | Slightly above the prior EA window, in line with developer intent |
| Mission modifiers | Rework | More readable on the mission select screen | Modifier icons now show a one-line effect description instead of a tooltip wall |
| Upgrade Grid readability | QoL | Hex-pattern board adds color coding | Easier to tell Standard from Rare from Epic at a glance |
| Armament License pacing | Tuning | Faster early unlocks, slower late unlocks | Reduces the late-game grind, raises the early-game tempo |
| Death Protection timer | Tuning | Shorter on solo, unchanged in co-op | Solo runs feel slightly more punishing at high threat |
The standalone known-issues list published alongside 1.0 explicitly calls out a Cranius achievement that will not unlock, two unnamed Fulfillments (activate relay towers; rescue bags of Saxitos) that do not progress, a Bunker Buster threshold bug, and a missing Mycologist cape. None of these are fixed in the 1.0.0 build itself; they are queued for the first post-launch patch.
Reading the Latest Mycopunk 1.0 Patch Notes
The 1.0 patch notes on Steam read like a hybrid changelog and roadmap tease, because the developer front-loads the rename pass, then lists new content, then buries the tuning notes at the bottom. If you skim, you will miss the parts of the build that actually changed under the hood — the HUB rework, the mission modifier rework, and the weapon scaling flatten are easy to overlook because none of them ship a single named item.
Structure of a Typical Patch Note Entry
The developer uses a consistent template for every mycopunk new update, which makes diffs easier to track across the mycopunk update history. Each entry is broken into a small fixed set of sections — Highlights, New Content, Balance and Tuning, Bug Fixes, and Known Issues — and the order rarely changes from build to build, so a reader who learns the layout once can skim the mycopunk 1.0 patch notes, jump straight to Balance and Tuning in the next entry, and immediately catch a Spawn Timer tweak without re-learning where anything lives.
| Section | What It Covers | Why It Matters |
|---|---|---|
| Highlights | Named new content (employees, regions, weapons) | First place returning players should look |
| New Content | Mission types, systems, NPCs | Often includes the Fulfillments or Armament License changes |
| Balance and Tuning | Numbers-only changes, no names | Easy to miss, but the largest single source of “the game feels different” reports |
| Bug Fixes | List of named fixes | Includes the Known Issues entries the developer expects to clear in the next build |
| Known Issues | Unfixed bugs the team is actively tracking | Read this before reporting a bug — the team may already be on it |
The Highlights block is also where the developer telegraphs upcoming themes. The pre-1.0 patch notes flagged Fungal Skewer, Sporelift, and the Mycologist by name several weeks before Expedition Alpha shipped, so anyone tracking the 1.9.5 → 1.10.1 changelog could see the fifth employee coming. Expect the next patch note entry to follow the same pattern: a Highlights block that names one or two new toys well before they ship.
Renames, Relabels, and Reclassified Items
The rename pass at 1.0 is the single largest terminology churn since launch. Below is the canonical list, including the underlying reason each change happened, which is usually a localization or trademark concern rather than a mechanical one. Players holding muscle memory from the Early Access build should note that prior save files auto-migrate to the 1.0 build without re-binding hotkeys, though any custom keybind that referenced the legacy "Acid" or "Shock" labels in third-party overlay configs will need to be remapped to Caustic Grenade and Voltaic Grenade respectively before the next mycopunk update.
| Old Name | New Name | Category | Reason (Per Developer) |
|---|---|---|---|
| Acid Grenade | Caustic Grenade | Grenade | Localization clarity in supported languages |
| Shock Grenade | Voltaic Grenade | Grenade | Same |
| Explosive Bullets (Accelerator) | Combustive Rounds | Attachment | More accurate description of behavior |
| Early Access build | 1.0 build | Version label | Marketing alignment with launch |
There is no mechanical change tied to any of these renames. Caustic Grenade still applies acid the same way, Voltaic Grenade still chains shock, and Combustive Rounds still detonate on impact. The only gameplay-visible difference is in tooltips and a small number of Codex entries that were rebuilt against the new strings.
Mycopunk Future Updates and Roadmap Hints
The mycopunk future updates plan is more transparent than most Early Access projects, because Pigeons at Play publishes a public roadmap on the official site and runs a beta branch on Steam. The roadmap below is the developer’s own published cadence; the actual mycopunk next update is the post-launch hotfix that addresses the items in the 1.0 Known Issues list. The full changelog, including the patch notes for the 1.0 launch, is detailed in our Mycopunk Full Release update coverage.
Confirmed Roadmap Themes
| Theme | Status | Likely First Appearance | Player-Facing Change |
|---|---|---|---|
| Clear 1.0 Known Issues | Confirmed | First post-launch hotfix (1.0.1) | Cranius achievement, two Fulfillments, Bunker Buster, Mycologist cape |
| Fulfillments list expansion | Confirmed in principle | Within the first 1.x window | More named Fulfillments added to the Codex |
| X11-B content depth | Confirmed, scope TBD | 1.1 or 1.2 | More room types, named sub-bosses, additional enemy modifiers |
| Mycologist upgrade tree | Not yet published | Unannounced | Currently only Sporelift, Fungal Skewer, and Infection are named |
| Additional employees | Not announced | Unannounced | No official name beyond the existing five |
| Snowball Grenade upgrade list | Unpublished by design | Unannounced | Developer has stated they “don’t want to spoil” the list |
| Diffraction Driver upgrade names | Unpublished | Unannounced | Only the alt-fire halo mechanic is confirmed |
| Threat 8 content | Not a thing (per developer) | N/A | 1.10.1 explicitly stated Threat 8 “isn’t a thing (yet)” |
The “not a thing (yet)” framing in the 1.10.1 notes is a deliberate tease — the developer left the door open without committing. Treat any community claim that Threat 8 ships in the next patch as speculation unless the official changelog names it.
The Beta Branch and How to Test Mycopunk Patches Early
Pigeons at Play runs a public Steam beta branch labeled something like “beta” or “public_test” under the game’s properties → Betas menu. Joining it lets you load the next mycopunk new update before it ships to the live build, with the trade-off that progress does not always carry over and some achievements are disabled. The beta branch is the source of the screenshots in most developer devlogs, and it is also where the first post-1.0 hotfix is currently being validated.
| Step | What to Do | Why It Matters |
|---|---|---|
| 1 | Right-click Mycopunk in Steam → Properties | Opens the install and beta menus |
| 2 | Betas tab → enter the access code (if any) | Some betas are open, some require a code from the Discord |
| 3 | Select the beta branch → wait for download | Patch size is typically 1–3 GB |
| 4 | Launch the game and check the version in the bottom-right of the main menu | Confirms you are on the test build |
| 5 | Report issues to the official Discord bug channels | Beta feedback shapes the live patch notes |
The beta branch is also where unannounced content occasionally surfaces early — players datamining the 1.0 build found several references to Snowball Grenade upgrades months before the developer officially published the “roll it down a hill to gain cartoon size” favorite. Treat datamined findings as rumor-grade unless the developer confirms them in a public post.
Comparing the Mycopunk Release Date and Platform Rollout
The mycopunk release date for 1.0 was October 20, 2026, after roughly 15 months of Early Access that began on July 10, 2025. The 1.0 build launched simultaneously on Windows PC (Steam) and PlayStation 5; no Xbox or Switch versions are confirmed by the developer, and any community claim of a console port beyond PS5 should be treated as unverified. Below is the platform-by-platform rollout, including the discount window and DLC pricing that shipped alongside 1.0.
Platform and Pricing Snapshot
| Platform | 1.0 Availability | Price (US$) | Discount | Discount Window | Notes |
|---|---|---|---|---|---|
| Windows PC (Steam) | October 20, 2026 | 14.99 | 50% off → 7.49 | Until November 3, 2026 | Launch discount |
| PlayStation 5 | October 20, 2026 | 14.99 (regional pricing varies) | Regional launch discount | Varies by region | Confirmed via the official PlayStation channel |
| Xbox Series X/S | Not announced | N/A | N/A | N/A | No official statement |
| Nintendo Switch | Not announced | N/A | N/A | N/A | No official statement |
| Steam Deck | Verified | 14.99 | Same 50% off | Same window | 1.0 build is Steam Deck Verified |
| Supporter Pack DLC | October 20, 2026 | Add-on (regional pricing) | None | N/A | Includes the Chrome skin |
| Soundtrack DLC | Pre-existing | Add-on (regional pricing) | None | N/A | Appid 4129370 |
The launch discount is a hard deadline; if you are reading this after November 3, 2026, the price reverts to 14.99 USD. The Supporter Pack and Soundtrack are separate DLC appids — they do not unlock automatically with the base game.
Achievement, Language, and Save Coverage at 1.0
The 1.0 build ships with 48 achievements, ten supported languages (English with full audio, plus French, German, Spanish-Spain, Japanese, Korean, Russian, Simplified Chinese, Traditional Chinese, and Portuguese-Brazil), and a single save slot that is shared across PC and PS5 only if you are on the same account family. There is no cross-progression between Steam and PS5, and no cloud-save mirroring for the Steam version beyond Steam Cloud itself.
| Coverage Area | Status at 1.0 | Caveat |
|---|---|---|
| Achievements | 48 total | A Cranius achievement is broken at launch and queued for the first hotfix |
| Voice acting | English only | Other languages are text-only |
| Subtitles | All 10 supported languages | Toggle in the settings menu |
| Cloud saves | Steam Cloud on PC, PS Plus on PS5 | No cross-platform sync |
| Cross-progression | None | Steam and PS5 saves do not share |
| Modding support | Preliminary mod support (custom upgrades); no Steam Workshop, no formal SDK at 1.0 | Developer implemented support for adding custom upgrades and sandbox mods |
| PvP | Not planned | The game is PvE-only |
| Battle pass | None | The game uses Fulfillments, not a season pass |
Players coming from other looter shooters often look for a battle pass and do not find one — the closest analog is the Fulfillments system, which is closer to a traditional achievement track than a seasonal grind. Fulfillments reward Hats and other cosmetic items, but the full list is not yet published, and two of the early ones (activate relay towers; rescue bags of Saxitos) were not progressing at launch.
What the Mycopunk Next Update Will Probably Fix
The mycopunk next update is going to be a hotfix, not a content drop. The developer’s own pattern from Early Access was to ship a hotfix within 7–14 days of any major build to clear the Known Issues list before adding new toys, and 1.0 is following the same cadence. Below is a working list of the most likely fixes, based on the published Known Issues and the developer’s history.
| Likely Fix | Source | Player Impact |
|---|---|---|
| Cranius achievement unlock | 1.0 Known Issues | Restores the missing achievement for players who already met the conditions |
| Fulfillments: activate relay towers | 1.0 Known Issues | Unblocks the cosmetic reward for the relay tower chain |
| Fulfillments: rescue bags of Saxitos | 1.0 Known Issues | Unblocks the Saxitos rescue Fulfillment |
| Bunker Buster threshold bug | 1.0 Known Issues | Restores the correct threshold check for the upgrade |
| Mycologist cape | 1.0 Known Issues | Restores the missing cosmetic on the 5th employee |
| Steam Cloud sync edge cases | Community reports (Discord) | Some users reported cloud-save desync after 1.0 |
| Co-op lobby filter edge cases | Community reports (Discord) | Filter occasionally shows closed lobbies as open |
The hotfix is also the place where the developer historically slips in small balance passes that did not make the 1.0 build. Pre-1.0 patches 1.9.5 and 1.9.8 both bundled small balance adjustments with their bug fix lists, so expect the 1.0.1 hotfix to do the same.
How to Stay on Top of Future Patches
The most reliable way to track the next mycopunk new update is to watch the developer’s official channels directly. Community wikis and third-party trackers are useful, but they tend to lag the official changelog by 12–48 hours, and during launch week that gap is enough to miss an unannounced hotfix.
| Channel | What You Get | Update Cadence |
|---|---|---|
| Official Steam news hub | Full changelog, devlog cross-posts | Every patch |
| Official website mycopunkgame.com | Roadmap, devlog archive | Weekly during EA, monthly post-1.0 |
| Pigeons at Play YouTube | Devlog videos, update trailers | Bi-weekly |
| Discord (discord.gg/mycopunk) | Patch previews, beta access codes, bug triage | Daily |
| Pigeons at Play on X | Short-form patch announcements, hotfix alerts | As needed |
| Instagram mycopunk_game | Visual devlog, art posts | Weekly |
| TikTok mycopunk_game | Short clips, patch teasers | Several times a week |
If you only bookmark one channel, make it the Steam news hub — it stores the canonical changelog for every mycopunk patch notes drop, including the mycopunk 1.0 patch notes and the full mycopunk update history going back to early access, so you can scrub through prior balance passes or revert confirmations without chasing screenshots across Discord pins. Treat the Discord as a faster-fire supplement for hotfix alerts and beta invites, but always verify wording against the Steam post before quoting it in a guide, because community reposts occasionally paraphrase stat values for weapon reworks and mutator tuning.
Frequently Asked Questions
Where can I read the official mycopunk patch notes?
The official mycopunk patch notes live on the Steam news hub for appid 3247750, and the developer cross-posts the full text to the official website and the Pigeons at Play YouTube channel. The Discord reposts highlights but is not a substitute for the full changelog. For pre-1.0 history, the same Steam news hub has every EA patch archived in chronological order.
What changed in the mycopunk 1.0 patch notes specifically?
The 1.0 build added the Mycologist employee, the X11-B region, Expedition Alpha and The Couch mission types, the Diffraction Driver and Snowball Grenade weapons, the Fulfillments cosmetic system, and a rename pass that turned Acid Grenade into Caustic Grenade and Shock Grenade into Voltaic Grenade. It also bundled a balance pass that flattened weapon scaling outliers and reworked mission modifier readability on the mission select screen.
When is the mycopunk release date for 1.0?
The mycopunk release date for 1.0 was October 20, 2026, after an Early Access run that began on July 10, 2025. The 1.0 build launched simultaneously on Windows PC (Steam) and PlayStation 5; no Xbox or Switch versions are confirmed.
What is in the next mycopunk update?
The next mycopunk update is expected to be a hotfix (likely 1.0.1) that clears the 1.0 Known Issues list, including the broken Cranius achievement, two unprogressing Fulfillments (activate relay towers; rescue bags of Saxitos), the Bunker Buster threshold bug, and the missing Mycologist cape. The developer historically ships a hotfix within 7–14 days of a major build, so the timing aligns with early November 2026.
How do I find the mycopunk update history in one place?
The cleanest single source is the official Steam news hub, which archives every patch chronologically from Early Access launch through 1.0. The official website mirrors the same content, and the Pigeons at Play YouTube channel hosts the visual devlog versions. For datamined or unannounced content, the public Steam beta branch and the Discord bug channels are the most useful secondary sources, but neither replaces the official changelog.
