Mycopunk Achievement Guide: All 48 Steam Achievements and Their Rarity

How Many Achievements Are in Mycopunk?

Mycopunk's list looks manageable until you reach the threat-level ladder and the collection grind at the end. A good Mycopunk achievement guide should tell you which unlocks happen on their own and which ones demand planning, so you don't waste a session on the wrong mission. This Mycopunk achievement guide sorts all 48 Steam entries by rarity, flags the ones that need a crew, and covers the two achievements that were broken until a recent patch.

The count is straightforward. According to the Mycopunk checklist published on mycopunk.net and reviewed on October 23, 2026, the Steam version has 48 achievements, while the PS5 release lists 49 trophies including a platinum. In other words, the PlayStation list adds one extra platinum on top of the same core set.

One bookkeeping warning before you start: version 1.0 added Fulfillments, an in-game achievement layer that runs alongside the Steam list. A Fulfillment pop is not the same thing as a Steam unlock, and browser checklists on fan sites only store your clicks locally — they do not sync to Steam. Treat any checklist as a memory aid, then confirm the real unlock on your platform's achievement panel.

Fast Wins: The Easiest Mycopunk Achievements

Most players knock out a large chunk of the list without trying. The table below uses Steam unlock percentages recorded by Exophase's Mycopunk achievement page, observed on October 25, 2026; the scope is global Steam players tracked by that site, so the numbers describe that sample rather than the entire player base.

A few practical notes from those entries:

• Upgrader is unavoidable. Anyone who finishes the tutorial and applies a single upgrade has it.
• Biome clears stack with threat clears. A single Gravity Farms run at threat level 1 can satisfy No Broccoli Please and Safe at the same time, which is why both sit above 88%.
• ABOMINATION! is a last-hit race. The description asks specifically for the final hit on an Abomination, so in co-op it can slip past you even if your squad clears the fight. Play it solo if you want certainty.
• Big Damage and Ow are passive. Dealing "a lot of damage" and taking "a lot of damage" both unlock through normal play, at 84.76% and 62.45% respectively.

The Rarest Achievements in Mycopunk

The bottom of the list is where a Mycopunk achievement guide earns its keep. All figures below are Steam unlock percentages from Exophase, observed on October 25, 2026.

Two of these are connected. Hoarder asks for 200 collected upgrades, while The Holder of All Things asks you to discover every upgrade in the game. If you are chasing the 0.02% entry, the 200-upgrade milestone will most likely fall along the way — so build one long-term loadout plan instead of two separate grinds.

Serial Killer sits just outside this table at 17.43% for 5,000 kills. It is not difficult, just slow: it rewards finishing missions rather than farming a single spawn, so it tends to complete naturally while you work through biome and threat clears.

Threat Levels, Biomes, and Mission Achievements

Roughly a third of the list is "complete a mission on X" or "complete a mission in Y." The threat-level achievements each carry their own unlock condition, and the unlock rates show exactly where most players stop climbing.

The drop from Onslaught to Predicament — 34.56% down to 3.46% — is the single steepest cliff in the list. Plan your threat climb as its own project on a build you trust, and treat threat level 7 as the finale rather than something to squeeze in at the end of a night.

Location-based unlocks are spread across the campaign and the side modes:

Two habits save real time here. First, pick missions by destination rather than by reward, because the Ice Floes, Swamp, and X11-B entries are all under 9% and easy to overlook while you replay comfortable maps. Second, learn the two score-based modes early — Incursion's floor 10 and Starrunner's 10,000-point target are the kind of challenges that get harder once you stop practicing them.

Co-op, Hidden, and Bugged Achievements

Crew-Only Unlocks

Four entries cannot be earned alone, and a Mycopunk achievement guide that ignores them will leave you stuck at 44 of 48.

• Full Crew — complete a mission with four different employees in your crew (30.36%).
• Yeehawwwww! — as the Wrangler, lasso another player (32.60%). This one is role-specific, so someone has to actually pick the Wrangler.
• BANG — make a basket with another player's broken body (16.97%). It is the rarest co-op entry in the list and needs a bit of coordination.
• Best Teammate — kill a member of your crew (51.29%). Morally questionable, mechanically trivial.

If you have one regular partner, queue together for Full Crew, Yeehawwwww!, and BANG in the same session rather than organizing three separate nights.

HUB Chores and Hidden Entries

Several unlocks live in the HUB rather than in a mission. Oops (knock over a pipe, 23.79%), I Want Saxitos (punch a bag of Saxitos, 41.15%), and Hi (say hi to Roachard, 34.37%) all take seconds once you know they exist. Calm Down extends Hi by asking you to say hi to Roachard a lot — it sits at 10.86%, which suggests plenty of players never repeated the interaction.

The fan checklists on mycopunk.net and VGTimes both flag eight entries as hidden or secret: Employee of the Month, Calm Down, Oops, Cranius, BANG, Ground Zero, The Broken Frame, and The Holder of All Things. Their unlock descriptions are simple once revealed — die 31 times, greet Roachard repeatedly, knock over a pipe, defeat Cranius, land the body-basket, finish Ground Zero, find the Broken Frame, discover every upgrade — so there is little reason to hunt blind.

Why Bunker Buster Did Not Unlock

If you met a condition and never saw the toast, check your version first. Per the Mycopunk checklist dated October 23, 2026, patch 2.0.1 fixed Fulfillment pops for Cranius and Bunker Buster. Update the game and repeat the trigger before you assume your save is broken or start a fresh run for a 1.43% achievement.

Mycopunk Achievement Guide FAQ

How many achievements does Mycopunk have? 48 on Steam, per the mycopunk.net checklist reviewed on October 23, 2026, and 49 trophies on PS5 including a platinum. The PlayStation list is the same core set plus the platinum.

What is the rarest achievement in Mycopunk? As of October 25, 2026, Exophase's Steam tracking recorded The Holder of All Things (discover every upgrade) at 0.02%, followed by The 10th Floor at 0.18%. Both are long-tail goals rather than single-mission challenges.

Can I finish this Mycopunk achievement guide solo? Almost. Full Crew, Yeehawwwww!, BANG, and Best Teammate all require another player, so at minimum you will need one co-op partner — and Full Crew specifically asks for four different employees in your crew.

Why did Bunker Buster or Cranius not unlock for me? Patch 2.0.1 fixed the Fulfillment pops for both entries, according to the dated checklist on mycopunk.net. Update the game, retry the trigger, and confirm the unlock on your platform's achievement list rather than in a browser checklist.
