Mycopunk Ground Zero Mission: Unlock Steps, Walkthrough, and Extraction Tips

Why the Mycopunk Ground Zero Mission Is Worth Unlocking

The Mycopunk Ground Zero mission does not sit on your mission board waiting for you — it is hidden behind a three-switch puzzle on Gravity Farms that plenty of squads walk straight past. That matters because this contract is where you pick up the Acid and the Globbler blueprint, and it doubles as a clean rehearsal of the drop-in, objective, loot, extract loop you will repeat everywhere else. This guide covers how to unlock the Mycopunk Ground Zero mission, what happens once you are inside the crashed ship, and how to leave with your rewards instead of donating them to the fungus.

Worth knowing up front: the free guides disagree slightly on how the unlock is delivered. A Gameplay Tips walkthrough for unlocking the Globbler describes a bunker that opens after three switches are flipped, revealing a consumable item that unlocks the mission. A Steam community thread about the last three weapons describes a room unlocked by three buttons, a transponder inside, and activation in the hub. The three-switch step is identical in both; only the hand-off differs. Treat the steps below as the reliable part.

Unlock the Mycopunk Ground Zero Mission on Gravity Farms

Start a run on Gravity Farms and, from your landing point, travel almost straight toward the big ring. You are looking for a bunker with three dark lights on it — those lights are your progress tracker, and each one switches on when you find its matching switch. All three switches sit behind breakable walls, so bring something that can smash through scenery.

With all three lights lit, the bunker opens and hands over the item that unlocks the Mycopunk Ground Zero mission. Community reports note the switch hunt works on Gravity Farms whether you enter through a standard mission or Paid Time Off, so long as the map is right — if the terrain does not match, you are in the wrong zone.

One caveat for readers who have seen the mission described as the game's opening deployment: at least one fan-written wiki frames it that way, but the unlock path above comes from players who actually ran the puzzle. Plan on earning access rather than expecting it to appear automatically.

Inside the Mycopunk Ground Zero Mission: Follow the Bubble

Once you are inside, the objective is refreshingly blunt — stay alive and follow the bubble. It leads you across the map to a crashed ship, which is where the real payoff is sitting. Inside the hull you will find two breakable walls; the left one hides a switch. Flip it and you are awarded the Acid and the Globbler blueprint, and a cargo pod is called down for pickup.

Everything before that switch is a survivability check rather than a puzzle. A community-written Ground Zero walkthrough breaks the contract into the same four beats every run uses, and it is a useful mental template:

• Briefing: read the objective wording and the extraction condition before you move an inch.
• Objective route: push to the marked area in a compact line instead of crisscrossing the map.
• Primary objective: regroup, then have one player trigger the objective while the others handle the response.
• Optional sweep: check side rooms and containers after the objective is secure, not during.
• Extraction: start the return trip before your ammo or inventory is stretched thin.

The step players skip most often is the first one. Starting a run without knowing the win condition is the most common first-attempt failure reported by new squads, and it costs you the entire deployment, not just a few minutes.

Enemy Threats and Loadout Choices for Ground Zero

Ground Zero sticks to the two baseline fungal threat types, which makes it a good place to learn their tells. Handle them correctly here and the deeper regions get noticeably easier.

Three habits carry most runs. First, positioning: fight around corners and vertical cover, never in a dead end, and always leave yourself one way out. Second, target priority: delete ranged threats early and stop dumping ammo into low-threat enemies. Third, ammunition discipline — the most frequent squad wipe in this mission comes from emptying magazines before the objective wave or the extraction defense, so budget your fire.

Loadout-wise you do not need anything optimized. The community walkthrough suggests three sensible lanes: a general-purpose damage build with ammo-efficiency upgrades for first-timers, a crowd-control build with radius and recharge upgrades if you expect to hold an objective, and a mobility-and-recovery build if you are running solo. Pick one purpose and put your early resources into the weapon or module that defines it.

Extraction Mistakes That Erase Your Ground Zero Progress

The most expensive misunderstanding in the Mycopunk Ground Zero mission is treating extraction as a victory lap. It is a defense phase. Dying on the way out can erase the value of the whole deployment, including everything you collected, so the run only counts when you are back in the hub with the loot banked.

Before you call it, run this short checklist:

• Confirm the objective and extraction condition during the briefing
• Complete the primary objective with the squad grouped, not strung out
• Grab at least the nearby resource containers after the objective is secure
• Leave yourself health and ammo for the return trip
• Review the run and fix one positioning or target-priority mistake before the next attempt

When you are ready to chase the other weapons, the Mycopunk page on Steam is the fastest way to confirm you are playing the live build the guides are written against.

FAQ

How do I unlock the Mycopunk Ground Zero mission? Run Gravity Farms, find the bunker with three inactive lights near the big ring, and flip the three switches hidden behind breakable walls — a silo to the right, a green/cyan building back left, and a globe structure to the left near the dome. The bunker then opens and gives you the mission unlock item.

Can I clear it solo? Yes. The objective itself is just survival plus following the bubble to the crashed ship, and community walkthroughs include a solo-oriented build focused on movement and recovery. Squad play simply splits the job of triggering the objective and covering the response.

What is the reward for finishing it? Flipping the switch behind the left breakable wall inside the crashed ship grants the Acid and the Globbler blueprint, and it calls down a cargo pod so you can extract the goods.

Why did my rewards vanish after a good run? You almost certainly died during extraction. Failing that final phase can wipe out everything the deployment earned, so start the return route early and defend the extraction point with clear sightlines instead of sprinting for it.
