Is it a bird? Is it a plane? No, it’s a deadly fungus!
As soon as you’ve made back some DNA points after hastily spreading your pathogen, it’s time to invest in some transmission abilities. Plague Inc.’s Air 1, Air 2, Water 1, Water 2 and ultimately the Extreme Bioaresol will ensure the spread of your fungus by land, by sea, and by air.
The Air abilities increase the infectivity of your pathogen in arid environments, as well as granting a greater chance of spreading the disease by plane. The Water abilities, on the other hand, allow the fungus to spread more rapidly in humid environments and by naval travel.
Plague Inc.’s Extreme Bioaerosol ability lets your fungus bypass filtration systems on airplanes and ships, which will greatly boost your infectivity by air and by sea and stack upon the Water and Air abilities. Pretty much the second you get your hands on this tier 3 ability, it’s almost a guarantee your fungus will spread to smaller island groups and other disconnected countries.
