Miami Zero Virus Research: How to Find All 7 Mutagens
Complete the Miami virus formula by collecting research subjects, testing drug combinations, identifying mutations, and finding all seven mutagens.
Updated:
Quick Answer
Check Dr. Schultz’s Wanted List and send the requested survivors to the Research Ward. Prepare a drug, administer it to a subject, and identify the resulting mutation.
Use the 3 × 5 experiment matrix to find unfinished combinations. Collect all seven mutagen fragments to complete the Virus Formula and unlock EUREKA!.
Miami Zero’s Research Ward contains 15 drug experiments, but only seven contribute fragments to the virus’s genetic sequence. The remaining experiments can provide equipment upgrades and other rewards.
This difference explains why the laboratory sometimes announces Recipe Successfully Studied without adding anything to the Virus Formula. The experiment has been completed, but its reward may not be one of the missing mutagens.
Each attempt also requires a research subject. Schultz requests particular survivors during checkpoint shifts, and those people must reach the Research Ward before you can continue experimenting. Managing the available subjects matters as much as choosing the next drug combination, especially when the campaign is approaching Day 15.
How to Unlock the Research Ward and Get Test Subjects
Schultz’s experimental work begins after he investigates an unusual drug found in a survivor’s blood.
The opening experiment introduces drug preparation and mutation identification. A successful transformation produces Green Giant and reveals Ag+, the first fragment of the virus formula.
After this introduction, the laboratory opens its larger research matrix.
The upper screen records the experiments you have studied. Beneath it, the Virus Formula display tracks the seven fragments required to finish the genetic sequence.
Send the Survivors Schultz Requests
During the checkpoint shift, Schultz provides a Wanted List containing photographs of people needed for his experiments.
Check the list before processing the survivor line. When someone matches a requested photograph, complete the inspection and select Research Ward as their destination.
The Research Center counter can show 0/2, indicating that two requested subjects are needed. Delivering both changes that counter, but it does not automatically complete their experiments.
Return to the laboratory after the shift and use the available subjects.
Sending a requested person to the yacht or another destination can leave you without that experimental opportunity. When this happens, continuing to inspect the laboratory equipment will not create another subject.
The Miami Zero walkthrough covers when the Wanted List becomes available and how its assignments fit into the daily campaign.
How the 15 Drug Combinations Work
The research matrix has three rows and five columns.
Each row represents a drug category:
- Pills: Shown as a collection of capsules.
- Powder: Shown as a small packet.
- Mushrooms: Shown with a mushroom icon.
The five columns represent different preparation methods. Their icons include crushing, heating, and other mechanical or mixing processes.
Selecting a drug and a preparation method gives one of the 15 possible combinations.
A checkmark means the corresponding experiment has already been studied. A question mark indicates a combination whose result has not yet been discovered.
Complete an Experiment From Preparation to Result
Once you have a subject in the Research Ward, the process follows a consistent order.
- Select an unstudied combination. Check the matrix for a question mark and choose its drug and preparation method.
- Prepare the drug. Use the corresponding equipment and complete its interaction.
- Administer the prepared substance. Bring it to the distributor connected to the occupied capsule.
- Observe the transformation. Allow the experiment to finish before choosing the mutation.
- Identify the mutation. Select the appearance that matches the transformed subject.
- Collect the result. Check whether the completed experiment awarded a mutagen or an upgrade.
The preparation stations do not all operate identically.
Some require you to keep an indicator balanced during processing. Another involves controlling heat. If the interaction has not finished, the drug is not ready for the distributor.
The same applies after the transformation. Until you submit the mutation identification, the experiment has not reached its final reward screen.
After clearing the completed experiment, return to the matrix and choose another unfinished combination.
How to Identify the Seven Mutation Appearances
The mutation identification screen tests whether you recognize the subject’s physical transformation.
The choices are not simply different names for the same condition. Size, body proportions, color, and skin abnormalities distinguish the possible results.
Giant Mutations
Green Giant is a large, muscular green figure. It appears in the introductory experiment that awards Ag+.
Red Giant has a similarly enlarged muscular body but red skin. A completed late-stage experiment identifies this mutation before discovering Br.
Violet Giant has the large build of the Giant mutations with a violet appearance. It also appears in an experiment that awards Hg.
The main distinction between these three is color. When several Giant options appear together, the body size alone is insufficient to select the correct answer.
Pygmy, Big Head, and Blisters of Pus
Red Pygmy and Yellow Pygmy both produce small bodies, but their colors are visibly different. Red Pygmy appears in an experiment awarding Kr, while Yellow Pygmy can appear in an experiment that gives an equipment upgrade.
Big Head produces a pale, thin body with an enlarged head. This appearance is different from the thick, muscular build of the Giants. One successful experiment identifies Big Head and awards Au.
Blisters of Pus produces numerous raised marks across the subject’s body. The visible skin changes distinguish it from the color-based Giant and Pygmy transformations. A completed experiment with this result awards Fi+.
Do not select a mutation simply because you remember receiving a particular reward from it previously.
The mutation identifies what happened to the subject. The reward depends on the completed experiment, and the final result screen confirms what you received.
All Seven Mutagens Needed for the Virus Formula
The complete Virus Formula contains these seven fragments:
Ag+ · Kr · Fi+ · Pt · Hg · Au · Br
Their labels appear beneath the research matrix. A collected fragment receives a completion mark, while missing fragments remain unfinished.
The laboratory does not require all 15 experiments to award mutagens. Only seven contribute to the genetic sequence; the other combinations can produce equipment improvements.
How to Read the Research Matrix
In this example, the player has already collected six fragments. The board also contains completed cells displaying rewards such as equipment improvements, ammunition-related bonuses, and money.
Those completed upgrade cells do not fill the remaining Br position.
There are four unstudied combinations visible on the matrix. Since the formula still lacks one fragment, the next practical step is to investigate the remaining question-mark cells with available subjects.
The important distinction is between the two displays:
- The upper matrix tracks which of the 15 combinations have been studied and their results.
- The lower Virus Formula shows whether the seven required genetic fragments have been collected.
You can have a nearly complete research matrix and still be missing part of the formula.
Can You Follow a Fixed Recipe Chart?
The reward positions shown in different Miami research states are not always identical.
For example, a pills-and-heating combination can appear with a mutagen reward in one research state and an equipment upgrade in another. Other corresponding cells can also display different rewards.
The reason for those differences is not established, so it is safer to use the results displayed in your current research matrix than assume a particular cell will always award the same fragment.
A successful experiment reveals its result permanently on the board. Use that information to avoid repeating completed combinations while missing fragments remain.
You do not need to predict every outcome in advance. Continue exploring unstudied combinations until all seven positions in the Virus Formula are filled.
Mutagen Rewards vs. Equipment Upgrades
When a recipe is completed, the result screen tells you what the experiment produced.
Mutagen Discovered means a fragment has been obtained for the Virus Formula.
Upgrade Acquired means the experiment has rewarded an improvement. The game instructs you to open a crate to collect it.
Some upgrades improve tools used during checkpoint inspections. One research reward enhances the UV Light so that ultraviolet traces remain visible longer. Another can improve the scanner’s detection capabilities.
These improvements are useful while you are still inspecting survivors, but they are separate from completing the genetic sequence.
Should You Collect Upgrades Before Finishing the Formula?
During the middle of the campaign, equipment improvements can make later inspections more manageable. An upgrade that improves visibility or detection may reduce the chance of missing dangerous symptoms.
Near Day 15, the decision changes if your Virus Formula is incomplete.
An available research subject is an opportunity to study one more combination. If the current objective is to finish the sequence, prioritize unstudied recipes rather than repeating an experiment whose upgrade has already been collected.
There is no requirement to discover every equipment improvement before EUREKA! unlocks.
Once the full formula is complete, any remaining research can be treated as an opportunity to collect useful optional rewards rather than a requirement for the genetic-sequence objective.
Why Virus Research Is Not Progressing
Several laboratory problems look similar because the experiment or formula remains unfinished. Check which stage of the process has actually stopped.
No Subject Is Available in the Capsule
Return to the checkpoint and examine Schultz’s Wanted List.
The laboratory requires experimental subjects. Selecting a new combination on the board cannot start an experiment when no subject is available.
If you already delivered the requested survivors, check whether they are ready for processing in the Research Ward. Otherwise, obtain the subjects requested during the next available shift.
The Preparation Equipment Will Not Finish
Each preparation method has its own interaction. Some require controlling heat or keeping an indicator within the correct range.
Continue the current equipment interaction until the substance is prepared.
If the drug has not been processed successfully, you cannot advance to the mutation result simply by returning to the distributor.
The Mutation Result Has Not Been Submitted
After administering the drug, inspect the transformed subject and select the correct mutation appearance.
Look at body size and color first, then check distinctive features such as the enlarged head or widespread pustules.
The experiment reaches its reward screen only after the identification stage is completed.
Recipe Successfully Studied, but the Formula Is Still Incomplete
This means the completed combination may have awarded an upgrade instead of a mutagen.
Check the result screen and compare the lower Virus Formula display with its previous state.
If no new fragment has appeared, return to the upper matrix and choose an unfinished combination.
For example, collecting five of the seven fragments leaves two more mutagens to discover, regardless of how many upgrade recipes have been completed.
How to Obtain Br and Unlock EUREKA!
The final fragment in one completed research sequence was Br.
That experiment combined pills with the bowl-shaped mixing preparation. After completing the processing interaction and administering the substance, the subject transformed into Red Giant.
Identifying the mutation produced the following result:
Br completed the seven-part genetic sequence and triggered EUREKA!.
That exact combination should be treated as a useful example rather than a guaranteed location for Br in every research matrix.
If your formula is missing a different fragment, continue with the remaining unstudied combinations. The objective is complete when all seven fragment positions have their completion marks.
What Happens After Completing the Virus Formula?
Collecting the final fragment finishes the genetic-sequence research objective and awards EUREKA!.
You can then check the laboratory matrix for any unclaimed upgrades, but the remaining recipes are not required to complete the formula itself.
Finishing the research also contributes to Secrets Revealed, which requires both the completed virus formula and a fully restored yacht.
If EUREKA! has unlocked but Secrets Revealed remains unfinished, check the ship’s outstanding compartments in the Miami Zero yacht repair instructions.
Both assignments need to be completed before the campaign’s final assessment recognizes them together. Completing the research alone does not guarantee that the yacht is ready or that every major Miami objective has been satisfied.
