Unlocking Next Plague Types and Genes
Every time victory in Casual Mode awards you a new gene. In both Normal and Brutal Modes, you get a gene and a new plague.
While the Standard plagues are available in the free version without needing to buy anything, the ability to use genes is a perk locked to the full version, as is the option to play the game in fast forward and the removal of all ads.
Please note that any Plague/Cheat type you unlock by playing the game is only available to you if you buy the full version.
Should you later decide the game is worth buying, all Genes you earned until then will be available to you. Note that any purchase unlocks the full version.
Thank you for playing!
