Fungus is the third challenge that awaits you in Plague Inc, and it works a little differently than the earlier stages. The key difference is that fungal spores have a hard time traveling long distances. Rather than relying on birds and airplanes to spread your disease, as in earlier modes, you’ll need to evolve fungal spore abilities to infect other countries.
Fungal spores make this level a little easier than Bacteria, since you can forcibly infect countries—looking at you, Madagascar—that are normally tough to reach.
Early game – Evolve Transmission Methods
Start in India. It’s a poor country with a warm climate and a ton of people, so your disease can grow exponentially without having to jump countries.
Evolve these transmission methods to get a foothold:
- Water 1
- Livestock 1
- Water 2
- Air 1
- Livestock 2
- Air 2
If any symptoms automatically mutate, devolve them immediately. You can’t let your disease show itself yet.
Mid-game – Evolve Abilities
By this point, your disease should have spread to at least five or six countries. As you earn more DNA points, your next set of Abilities should be:
- Extreme Bioaerosol
- Drug Resistance 1
- Cold Resistance 1
- Cold Resistance 2
At this point, your disease should still have no symptoms. Keep an eye out for them and devolve them as needed. Keep gathering DNA points until you’ve infected nearly the entire world. You should be pretty close to 100 by the time you move on to the next step. Once you have less than 8 countries to infect, evolve Spore Burst to reach them. If there are additional countries to infect, evolve Spore Burst again.
Endgame – Evolve Symptoms
Once there are zero healthy people left in the world, you’re ready to evolve symptoms and turn your disease deadly. This path is very efficient:
- Internal Haemorrhaging
- Hemorrhagic Shock
- Systemic Infection
Now, sit back and wait. If any new symptoms arise, let them do their thing. You can also evolve Coma and Total Organ Failure as well, once you have the DNA points. Pop any Cure bubbles that appear. Its unlikely researchers will be able to outpace the disease, but if they seem to be moving quickly, evolve Genetic Hardening I to be sure.
