In Plague Inc. for the Android & iOS (iPhone, iPad, iPod Touch, etc.), there are several different plague types to play with, but only Bacteria is unlocked by default.
You can pay money to unlock all of them quickly, but where’s the fun in that?
The next plague in the list is unlocked as you beat one, so to unlock the Virus type, you just need to win your first game against Bacteria, and to unlock Fungus, you need to beat Virus, and so on.
Check out my other article on beating Bacteria on Normal if you’re having trouble. Also check out my article on unlocking genes, which will help tremendously with beating future plague types.
