Before a player starts their game, they can insert Genetic Code. These genes allow personalization of pathogens by providing boosts to how one infects people, reacts to different environments, acquires DNA, and just the playstyle in general of your pathogen.
Every time a player wins a game with a standard plague, they unlock one of the 25 genes, regardless of the difficulty level. The same goes for victories in the Neurax Worm. However, the other special plagues normally unlock one of their special genes. There are five different types of genes: DNA Genes, Travel Genes, Evolution Genes, Mutation Genes, and Environment Genes. Players can only have one of each type of gene per game, meaning that there are a large number of different genetic combinations that one can use for any disease (3,125 to be exact) . There are exclusive genes for Necroa Virus, Simian Flu, and Shadow Plague. On Android, you must buy the premium version for $1.00 in order to use the genes that you unlocked.

Travel Genes
Teracyte
This gene increases the chance of your plague spreading by land (+7 land).
This gene is useful for infecting areas with multiple countries in close proximity to one another, such as Asia.
Aquacyte
This gene increases chance of your plague spreading by sea (+7 sea).
This is useful in situations where Island Countries can be particularly difficult to infect, such as Pirate Plague.
Aerocyte
This gene increases chance of your plague spreading by air (+7 air).
This is useful in situations where planes are less common than usual, such as Volcanic Ash and can boost Saudi Arabia games.
Suppression
Your plague is more likely to cross a closed land border. This is useful in bypassing situations where a plague would usually be locked out, such as shortly after discovery.
This gene is particularly useful in scenarios such as Xenophobia and Shut Down Everything.
Native Biome
This gene increases infectivity of your plague in its starting country.Environment Genes
Xerophile
This gene gives your plague a bonus in arid climates (+0.5).
This is useful in spreading in countries with an Arid climate, such as Saudi Arabia.
Hydrophile
This gene gives your plague a bonus to infectivity in humid climates (+0.5).
This is useful in spreading in countries with a Humid climate, such as India.
Rurophile
This gene gives your plague a bonus to infectivity in rural environments (+0.5).
This is useful in spreading in Rural Countries, such as Argentina.
Urbophile
This gene gives your plague a bonus in urban environments (+0.5).
This is useful in spreading in Urban Countries, such as China.
Extremophile
This gene gives your plague a minor bonus in all environments (+0.2 in all environments).Evolution Genes
Note: Mega-Brutal infected population cost increase still applies to the "stasis" genes. Cost will still increase, just at a lesser extent than without the "stasis" genes.
Ionised Helix
This gene grants bonus DNA when devolving (+2 DNA Points for devolution).
This gene is useful at lower difficulties because devolution of low-tier Symptoms, for example, frees up DNA Points that can be used to evolve higher-tier symptoms. In general, it reduces the total cost.
Translesion +
Costs to devolve don't increase. This is useful with Virus and/or high difficulty modes, because of high amounts of symptoms and high costs of symptoms respectively.
Sympto-Stasis
Symptom costs don't increase, but your plague will be easier to cure(-0.1 infectivity in all environments, -0.1 cure requirement).
Caution is advised when considering the use of this gene at higher difficulties. This is a very powerful gene for all standard plagues of which it is available, as costs can skyrocket to expensive heights.
Trans-Stasis
Transmission costs don't increase, but your plague will be easier to cure (-0.1 infectivity in all environments, -0.125 cure requirement).
Caution is advised when considering the use of this plague at higher difficulties. Useful for Neurax Worm.
Patho-Stasis
Ability costs don't increase, but your plague will be easier to cure (-0.1 infectivity in all environments, -0.11 cure requirement).
Caution is advised when considering the use of this gene at higher difficulties. Useful Fungus and Bio-Weapon, because each spore bursts can be bought with 1 DNA point and Unlock Annihilate gene and Gene Compression can be bought easily respectively.Special plague genes
Necroa Genes
(Exclusive to Necroa Virus, replacing Evolution)
Autolytic Reduction
This gene slightly decreases the speed at which zombies decay, allowing them to be dangerous for longer periods of time.
Cytopathic Boost
Infected corpses are more likely to reanimate as a zombie.
ThermoNecro
This gene reduces the zombie rate of decay in countries with a Hot climate.
This increases the effectiveness of zombies in hot countries.
Can be combined with Mummification for effectiveness.
Spliced Activation
Active abilities cost less DNA (from 5 to 3) to use.
This allows the player to invest more DNA Points in improving the deadliness of their zombies if they wish to do so.
Dopamine Inhibitor
This gene increases the chance of a zombie victim becoming a zombie.Ape Genes
(Exclusive to Simian Flu, replacing Mutation)
Viral Affinity
This gene increases the rate of ape-to-ape transmission.
Call of the Wild
Apes are less likely to be found by humans.
This gene can be used to ensure the humans take a longer time to figure out that the Simian Flu is causing the apes to behave erratically.
Together Strong
This gene increases DNA gained from colonies (+1 DNA).
Leadership
Active abilities cost less DNA to use (1/2 cost).
This gene allows the player to invest more DNA Points into either improving their apes or negatively impacting humans.
Adrenal Surge
This gene increases ape strength and speed, but it is lethal over time.
The latter portion makes this gene potentially useful in a Simian FluArtificial Genes
(Exclusive to Simian Flu, replacing Evolution)
Cortisol Sensitivity
This gene reduces research from Gen-Sys experiments on apes.
This has the effect of reducing the effectiveness of the Cure effort.
Latent Catalyst
This gene allows you get DNA when a Gen-Sys lab is destroyed.
Ion Deficit
It costs more to devolve, but it also makes the Simian Flu harder to cure.
Ion Surge
It costs less to devolve, but the Simian Flu is easier to cure.
ATP Overdose
Bonus DNA is given at the start, but it costs significantly more to devolve (+15 starting DNA Points), (20 more points devolution cost).Shadow Genes
(Exclusive to Shadow Plague, replacing DNA Genes)
Witch Doctor
Vampire heals faster when in its lair
Shadow Spawn
Vampire less likely to be spotted in countries with lairs
Mad Scientist
All bubbles are automatically popped for you
Unholy Engineer
Harder for drones to target lairs
Frugal Researcher
Lair DNA bonus triggers with fewer infected peopleBlood Genes
(Exclusive to Shadow Plague, replacing Travel genes)
Healthy Eater
Increases vampire maximum health
Brawler
Vampire Blood Rage ability doesn't cost DNA
- This is means blood rage ability's costs will be disabled, making it similar to Budget Bat.
Harvester
Vampire gets more DNA when consuming people using Blood Rage
Scavenger
Vampire gets more DNA from destroying labs and Templar Bases
Berserker
Vampire Blood Rage ability kills more peopleFlight Genes
(Exclusive to Shadow Plague, replacing Environment genes)
Bat Bolt
Vampire Flight range increases
Fair Weather Bat
Vampire flies faster when not injured
Socially Awkward Bat
Vampire starts Blood Rage automatically when entering a new country
- Doesn't work with Brawler.
Budget Bat
Vampire Flight ability doesn't cost DNA
Aerophobic Bat
Vampire flies faster but damages healthUnlocking via Gameplay
You can unlock genes by playing the game. Below are some ways people found which gene gets unlocked by which action, mostly tested on mobile (Android/iOS):
- Beating a Bacteria, Virus, Fungus, Parasite, Prion, Nano-Virus, Bio-Weapon, Neurax Worm level likely unlocks any random gene.
- Beating a Necroa Virus level likely unlocks a Necroa Gene
- Beating a Simian Flu level likely unlocks a Simian/Artificial Gene
- Beating a Shadow Plague level likely unlocks a Shadow/Flight/Blood Rage Gene

Trivia
- The Mutation Genes,(Base Oxidisation & Base Hydroylsis) Evolution Genes, (Sympto-Statis, Patho-Statis, & Trans-Statis) And Multiplayer genes have good and bad sides.
- Neurax Worm is the only special plague that dosen't have its own special genes.
