3 Cheat Plague Types
The 3 cheat plague types are the ultimate reward for the most experienced and highly strategic players. They allow for these players to "play" around with the world through the several cheats available. Unfortunately, only one type of cheat can be activated at any one time. The cheat plague types cannot evolve any special abilities of the 7 standard plague types (In order, Bacteria, Virus, Fungus, Parasite, Prion, Nano-Virus, Bio-Weapon) or the Neurax Worm. The cheat plague types will evolve transmission traits and symptoms identical to the 7 standard plague types. Here is the breakdown of what each cheat plague type do. Immune Plague: Your Plague cannot be cured; Cure research progress stops at 99%. Hidden Plague: Governments of nations are unable to take actions to stop the plague in any way; This means governments cannot prevent the transmission of your plague. Unlimited Plague: You will start the game with 2,000 DNA points, which is enough to evolve every single trait, be it transmission, symptoms or abilities.
Unlock the other 6 standard plague types, and the Neurax Worm
When you first start out in the game, there will only be one plague type available: Bacteria. The 6 other plague types can be unlocked in progression. The order of unlocking is as follows: Bacteria -> Virus -> Fungus -> Parasite -> Prion -> Nano-Virus -> Bio-Weapon. Unlocking the Neurax Worm is more demanding, though. All plague types can unlocked through in-app purchases. Note that beating any game on casual difficulty will not unlock the next plague type.
