Cheats are abilities, not traits, that can be enabled in any combination, allowing for 2^7 different combinations, or 128. All cheats are usable by all standard plagues, special plagues and scenarios.

In Plague Inc. The first four can be unlocked either by beating all regular plague types on Brutal Difficulty, the next three on Mega Brutal Difficulty or by purchasing them ($13.99). In Plague Inc. Evolved, the first four cheats can be unlocked by beating all of the Plague types in normal difficulty, and the last three by completing all Plague types in Brutal.

Each cheat option has biohazard markers indicating which difficulties of which it was beaten, just like the Scenarios and other Standard Plagues and Special Plagues.

The cheat plaguesEdit

Immune StrainEdit

Although the cure is being developed, the cure never finishes. This is done by the cure requirement increasing as more cure progress is completed

  • The only way to lose is by killing off all carriers while there are still healthy people alive.

Hidden StrainEdit

Governments will never research cures or close borders or ports.  Like the Immune strain, the only way to lose is by killing all victims without infecting everyone first.

Unlimited StrainEdit

Grants "∞" DNA at the start of the game. Can be used to determine how to unlock symptom combos.

The value granted may be 9999 in Plague Inc. Evolved.

Turbo StrainEdit

The starting country will immediately be completely infected.

Shuffle StrainEdit

All evolutions are randomly shuffled in all possible trait spots.

Lucky Dip StrainEdit

Start the game with 5 random evolutions (Can't be devolved), and act as if they were normally purchased, and lead to adjacent traits.

Double Strain Edit

Allows the disease to start in two countries.


Trivia Edit

  • You won't be able to get achievements while cheating, nor it will count toward scores, with the exception of "Normal/Mega Brutal Shuffle", "Bingo!" and "Lottery winner!".
  • One cannot use multiple achievements at once to get biohazards for cheats.
  • In Plague Inc., If one completes a cheat in a higher difficulty and then a lower difficulty, then the biohazards in the higher difficulty will be exluded if they are not the same difficulty and higher than that of the lower difficulty of which the game is played. For example, if one uses a cheat in Mega-Brutal Difficulty and then Casual Difficulty, then after the casual game is played, only the biohazard to indicate that the cheat has been completed in casual difficulty will be present.
