Step-by-Step Guide
-
Step 1: Choose your genes.
When starting the game, you will be able to choose a few upgrades for your virus.
What you choose here will have a huge impact on how the game plays out, so choose wisely.
There are a few suggested upgrades that you should pick to make this game easier:
DNA Gene
- ATP Boost.
This will give you extra DNA points at the beginning, which is essential for slowing down the cure.
Travel Gene
- Aquacyte.
Basically required to infect difficult islands like Greenland, Iceland, and New Zealand.
Evolution Gene
- Sympto-Stasis.
This will keep symptom costs low.
Mutation Gene
- Genetic Mimic.
This slows the cure progression, which is important because the search for the cure starts immediately.
Environment Gene
- Extremophile.
This boosts the infection rate in every environmental condition. -
Step 2: Buy some initial upgrades.
Before choosing a starting country, use your ATP Boost bonus to purchase a few starting upgrades.
These will make your life much easier later on in the game, and will help mitigate the cure.
Code fragment interception
- This will help slow down the cure.
Coughing Cysts Abscesses Insomnia Paranoia , Your starting country is very important, as this will determine how quickly the virus starts spreading.
Most guides recommend starting in India due to the large population and proximity to China, though others suggest Saudi Arabia.
As soon as you choose a country, work will begin on the cure. , At the start of the game, you should prioritize certain upgrades to give you a much better chance later on.
As you start collecting DNA, evolve the following upgrades, in order as soon as you can afford them:
Code segment interception Nausea Vomiting Drug Resistance 1 Genetic Hardening 1 and 2 , If you receive pop-ups informing you that planes or ships have been sterilized, you should prioritize the corresponding transmission methods:
If airplanes are sterilized, evolve Air 1 immediately.
If ships are sterilized, evolve Water 1 immediately. , Your next few upgrades are aimed at slowing down the progression of the cure.
These symptoms make the cure more difficult, and should be evolved as soon as possible:
Hyper-sensitivity Paralysis Coma Seizures Insanity , The following upgrades make your virus harder to kill and more likely to spread.
Evolve these quickly to increase the rate which your virus infects new countries and decrease the cure's research rate:
Radical elements stabilized Water 2 Air 2 Extreme bioaerosol Drug Resistance 2 Cold Resistance 1 and 2 , Now that your virus is spreading, it's time to evolve some more symptoms.
These will increase the infection rate, leading to an even quicker global infection:
Pneumonia Sneezing Rash Sweating Anemia Hemophilia Skin Lesions Diarrhea , There are a couple more upgrades that you should focus on to decrease the cure progress.
These are not available until late in the game:
Encryption Breached Drug Immunity , Once every country in the world is infected, this ability can increase the infectivity of your virus.
The downside is that after a short time, the infectivity will decrease to lower than its original value, so only use this after all countries are infected. , Occasionally, your virus will randomly mutate.
It's highly recommended that you devolve these symptoms as they appear, as they can start killing people before the infection spreads to everyone. , Towards the end of the game, you will be racing against the cure.
The Genetic Reshuffle ability will slow down the cure's progress, and is a good investment when you don't have much else to evolve.
There are three levels, each of which will set the cure back. , When every person in the world is infected, you will receive a pop-up message.
At this point, you're safe to evolve every lethal symptom, as you don't have to worry about infecting new people.
At this point, the faster you can kill everyone off, the better. -
Step 3: Choose a starting country.
-
Step 4: Evolve essential upgrades.
-
Step 5: Deal with sterilization.
-
Step 6: Slow down the cure.
-
Step 7: Increase the infection rate.
-
Step 8: Evolve more symptoms.
-
Step 9: Harden your virus.
-
Step 10: Use Replication Factory Overload.
-
Step 11: Devolve random symptoms.
-
Step 12: Shuffle your genes.
-
Step 13: Evolve every symptom once everyone is infected.
