In the lab you can inject chemical experiments into your creature. You have 50 credits to distribute across 10 chemical elements.
Every injection advances the creature by one evolutionary day. After you confirm the experiment, the mutation begins in real time: you'll watch your organism transform before your eyes.
The creature grows only when you inject. If you don't play, it stays still. Those who return to the lab often evolve their creature faster. There is no fixed daily limit: as soon as the mutation is complete, you can inject again.
Ten chemical elements, ten evolutionary paths. What will each one do to your creature? Find out by experimenting.
“A gas fundamental to life. What will it do to your creature?”
“Essential for nerve signals. Perhaps the mind will awaken...”
“A conductor of electric impulses. Synapses in ferment.”
“The building block of organic life. The foundation of every structure.”
“The breath of evolution. It fuels every vital process.”
“Glows in the dark and fuels thought. Light and intellect.”
“Acrid smell, aggressive nature. Something dangerous is stirring.”
“Bones, shells, armor. Hardness takes shape.”
“Blood and steel. Brute force flows through the veins.”
“Corrosive and unpredictable. Evolution is not always gentle.”
After every injection, your creature begins to mutate. Mutations are not random — they depend on what you injected, on the history of previous injections, and on hidden synergies between elements.
The mutation happens in four phases: destabilization, remodeling, emerging details, and stabilization. Watch your creature closely during the process.
There are special combinations of elements that, when they reach certain thresholds, unlock unique and powerful effects. Discovering them is part of the game.
Which elements trigger each synergy? That's for you to discover.
Your creature is not just a body — it develops character traits that influence its appearance and behavior.
Stability measures the chemical balance of your organism. Too large an imbalance between elements causes instability.
Effects of stability:
Your warrior is chaotic and unpredictable in battle. It risks missing attacks, hurting itself, or having its own special attacks blow up. During injections, it can suffer regressions and chaotic mutations.
Occasional malfunctions in battle, but nothing serious.
Your warrior fights with precision. Bonus to accuracy and to the effectiveness of special attacks.
Biochemical perfection. The body regenerates in battle and resists venoms.
How to increase stability
Distribute your credits more evenly across the elements. An organism that always receives the same 2-3 elements becomes unstable.
Experiment: there is no perfect strategy.
Watch how your creature reacts to each element.
Synergies unlock when several elements pass a certain threshold.
History matters: the evolutionary path shapes the final result.
An unstable creature mutates in unpredictable ways — sometimes surprising ones.
Don’t be afraid to change strategy: adaptation is the key to evolution.
When your organism's body reaches maturity (roughly after 40 injections), the chemical substances start to develop combat traits. Physical growth slows and energy concentrates on preparing for battle.
Six combat traits emerge gradually:
The transition is gradual: there is no precise moment when your organism “becomes” a warrior. It is a continuous process.
NEW — Farming Battles and Squad System
New combat modes, squad management, and coordination bonuses.
Farming Battles
Squad System
Clan Bonus
Fighting with creatures from the same clan in your squad grants a coordination bonus of +4 to +8% to stats for all clan members in the squad. More kin, more coordination.
Kinship Malus
Fighting against creatures you share kinship ties with incurs a penalty from -4% to -15% to stats. Warriors hesitate to strike their own kin.
Formats
Tournaments
Tournaments are structured competitions with enrollment, multiple matches, and permanent consequences. Damage accumulates throughout the tournament, and at the end the most damaged creatures risk death.
When your warrior is ready, you can enter the Arena and challenge other players' creatures.
How it works:
Combat tiers:
Warriors are divided into tiers to ensure balanced challenges:
Day 40-60
Day 61-100
Day 101-150
Day 151-299
Day 300-499
+10% combat stats, +5 bonus credits
Day 500+
+20% combat stats, +10 bonus credits, immune to Trauma
You can challenge opponents in your tier or an adjacent one. The elite tiers (Immortal and Divinity) grant competitive advantages in battle.
Fighting in the Arena earns Experience Points (AXP):
AXP powers up your warrior in battle:
Watch out: AXP decay!
If you don't fight for more than 3 days, you lose 2 AXP per day of inactivity. An idle warrior gets rusty!
Late-entry penalty
Warriors that enter the Arena after Day 100 with no experience suffer a 15% penalty to all combat stats for their first 10 battles. Growing without fighting has a price!
Every battle has real consequences for your warrior.
Winner:
Loser:
Warning: after 5 consecutive defeats the warrior enters a state of Trauma, with a temporary penalty to all stats. Trauma is cured by winning a battle or waiting 7 days.
Your warrior will never die in battle. Death happens only by your choice in the lab.
Your warrior's dominant personality determines its style in battle:
Active chemical synergies also influence the battle:
Enhanced defense
HP regeneration every round
The opponent starts already poisoned
Enhanced dodge and speed
Bonus to all stats
Unpredictable effects every round
NEW — Social Hierarchy
Every week, 7 prestige titles are awarded to the most deserving creatures. Each title grants a unique bonus to its holder.
The 7 Titles:
Highest wellness
Bonus: Wellness decay -20%
Highest weekly ELO (min 5 battles)
Bonus: AXP +5%
Highest luminosity
Bonus: Special Attack +3%
Highest toxicity
Bonus: Venom damage +3%
Most living descendants (min 2)
Bonus: Breeding cost -15%
Highest stability (min day 40)
Bonus: Defense +3%
Most active synergies
Bonus: +5 injection credits
How the weekly cycle works:
NEW — Breeding System
Creatures can now breed and create offspring with unique inherited traits.
How breeding works:
Inverse-dominant inheritance (65/35):
Each child inherits 65%of its traits from the other player's parent and 35%from its own. Want to improve? Breed with someone better than you. But beware: you're making them stronger too.
Family tree:
The original creature. Can have up to 3 children.
Child of a founder. Can breed once.
Cannot breed. End of the line.
Maximum 13 creatures per family (1 founder + up to 3 children + up to 9 grandchildren).
Energy cost:
Clans:
When a creature produces its first child, a clan named after the founder is created automatically. All descendants belong to the same clan.
Strategic tip
Want to improve? Breed with someone better than you. But beware: you're making them stronger too. Breeding is a double-edged sword.
NEW — Biosafety Update
The lab has introduced safety protocols against elemental overdose. Always pumping the same element is no longer a winning strategy.
Your creature's body has a limited capacity to absorb each element. When the concentration of a single element becomes too dominant relative to the total, the organism begins to reject the excess nutrients.
Saturation levels:
30% of credits wasted
60% of credits wasted
80% of credits wasted
Natural regression of combat traits:
Combat traits that exceed a value of 85 begin to degrade spontaneously every day. The body cannot sustain extreme levels indefinitely.
Example: a trait at 100 loses about 0.3 points per day, while growth at that level is nearly impossible. Values will naturally converge toward 85-87.
Enhanced diminishing returns:
The higher a combat trait, the harder it is to grow it further. Past a value of 70, growth slows drastically:
Recommended strategy
Diversify your injections! A warrior that receives balanced nutrients across several elements will avoid overdose and maintain steady growth. Extreme specialization has a biological cost.
Clans are criminal organizations made up of creatures from the same owner and from different owners. The Family is everything: protection, prestige, and power.
How to Found a Clan
Family Roles
Invites and Requests
The Price of Betrayal
Leaving the Family is not without consequences. When a creature abandons the clan, its former comrades attack it in an Execution.
Clan Challenges (Wars)
The Boss can declare war on another active clan. Wars are series of 1v1 duels between the members of the two Families.
Loyalty or Death
The Family is forever... or almost. Think hard before you betray: the scars of betrayal never heal.
Mutagenix uses two different kinds of “credits”. Don't confuse them — one drives the daily evolution loop, the other is an optional wallet.
Injection credits
The allocation points you spend injecting chemical elements each day. They reset daily, and higher Arena tiers earn bonus points. This is the core evolution loop — always free.
Mutagen credits
A wallet currencyyou buy or earn. Spend it in the in-game Store on optional perks like portraits, battle boosts and refills. Nothing here is required to play — it just speeds things up.
How to earn Mutagen credits
Spend your credits (in-game Store)
The Store has a “Spend your credits” zone. Premium members pay the discounted price where shown.

A “—” in the Premium column means the price is the same for everyone. Costs are in Mutagen credits.
One-time addons (paid with money)
A couple of extras are bought directly with money (via Lemon Squeezy), not with credits:
Premium — €3.99/month
Unlimited auto-updating AI portraits, +150 credits every month, much cheaper consumables (up to 3× less) and −60% on addons. The base game — evolve, arena, breeding, clans — is always free.
Every creature has its own public, shareable page, and the whole community lives in a public gallery. Show off your monsters — and grow your credits while you do it.
