How to Beat Plague Inc. Bacteria on Normal

Updated on August 29, 2016

A Walkthrough of Plague Inc. Bacteria on Normal

Looking for a walkthrough of Plague Inc.'s Bacteria on normal? Look no further! Recently, I've updated the original walkthrough to something a little easier, with less frills—a more direct approach. This walkthrough of Bacteria on Normal is 100% guaranteed to succeed: it has worked five times for me so far, so I am going to go ahead and release it to the public. Good luck!

First and foremost, some rules for completing the walkthrough:

  • Devolve all symptoms until everyone in the world is infected. There will be a message for this.
  • Follow the walkthrough to the T; build the points to the exact amount.
  • Burst: all bubbles, new infected countries, and so forth.
  • Purchasing the game adds more fun without all the ads. The purchased version also comes with the ability to fast forward, to change DNA stuff, and cheats!
  • Have fun!

  1. Start your Bacteria in South Africa.
  2. Build your points to 50. Devolve any symptoms. Put points into: Air 1, Water 1, and Water 2.
  3. Build your points to 100. Devolve any symptoms. Put points into: Drug Resistance 1, Drug Resistance 2, Heat Resistance 1, Air 2, and Extreme Bioaerosol.
  4. Build your points to 30. Devolve any symptoms. Put points into: Cold Resist 1 and Cold Resist 2.
  5. Build your points to 100. Devolve any symptoms until everyone is infected.
  6. Once everyone is infected, start your points in any symptom. I prefer to start with Insomnia.
  7. Work your way to the middle where you will find Total Organ Failure (image below.)

This is your ticket to killing everyone in the world. Congrats!

        Worked flawlessly, damn!

        I've just had the right idea, even did the "wait until everyone gets infected", devolving any symptoms and even trying to get to the middle of all symptoms, but always fall short of dna point. The key in my personal case was that raising/waiting without improving more than just a little the abilities and transmitions tabs.

        Anyways, thanks dude for your service!

        Worked beautifully!

        Turns out I had the right idea before I saw your guide, I was just going about it the wrong way... I didn’t think to not have ANY symptoms... in fact, I didn’t even know it would continue to spread without them. I think that was my downfall.

        Anyway, guide works perfectly first time. Good job explaining simply and effectively. Kudos.

        Ignore my previous post...that was for casual difficulty. I follow the same method for normal, but my stats are not nearly as high.

      • profile image

        Aldones 6 months ago

        Based on the reviews this seems a bit of a lengthy process. I usually can get bacteria on normal in about a year with the cure around 30%. Start in China (boring but the tutorial often has reasons for its madness). Focus on air and water, max all 5 nodes. Take drug resistance 1 and 2. Grab blood 1 and 2. By now you will likely have the majority of the world infected and can start focusing on all the lethal symptoms you can find, don't devolve anything unless you (1) have the world infected and don't need transmissions anymore or (2) end up killing yourself off faster than the disease can finish spreading. Heat and cold resistance is good for when a plague is in a country but spreading too slowly...know your geography! Note: I usually will need at least 1 point in cold for Greenland, Iceland, and Canada.

        I haven't tried brutal yet and currently mousing through fungus.

        I just wanna say, I took some cues from the post, and some hints from the comments section, and I succeeded! Poor humans had their cure progress at 36%! As someone else here said, it's best to start your disease in Saudi Arabia. Also, stock up on DNA points on step 1 itself. This will take longer, but is more effective. I had more than 100 DNA points before I evolved MY bacterium. It also helps to buy the full game, as that gives you access to the fast forward feature. Thanks a lot to everybody here!

        If you do this exactly as explained (though it will take a little longer) you will complete the level. Saving the points will take a while, but its worth the wait when you succeed. Also be sure to fight the cure by adding in the Abilities to reduce cure speed 1 and 2. You may even be able to add the Ability to increase cure workload. But do not add these abilities until you have followed all of the above instructions. I was able to beat the cure with it only have completed 56%
