How to Beat Plague Inc. Bacteria on Normal

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!

"Trains," you wine drinking wine-o. May fire rain down on your soul. Apparently the cheat is strong in you, because I didn't come to your tutorial on how to be a "regular non-winner." Actually, I just really liked the style of your comment so I decided to make one similar. I really don't want fire to rain on your soul. Actually, I think I love you. That moment we just had just now.. I think it's the happiest I have ever been. Will you marry me?

"Juice", you ungrateful sod. A pox upon thee. Maybe if you didn't "waste" so much time looking to cheat the game you'd actually learn something and beat it legitimately.

Thomas 5 weeks ago

1,016 days. The cure was 31% completed. Throwing in the genetic hardening/reshuffle helps if you have the extra DNA.

alex 2 months ago

if you start in a hot country (egypt/saudi arabia are the best imo) you can skip heat resistance 1. Also for total organ failure go from the coughing tree-line because you need fewer points for that. You also don't need to gather so many points for the upgrades. I just upgrade the moment I get the points for each one. Air1 Air2 or water1 then the other one. water 2 , extreme bioaerosol, then drugs 1 2 cold res 1 2. Then wait for all to be infected. GG

First i would just like to say thank you for the beginning advice/tips, they have helped me drastically when it came to spreading my plague, etc. Now i don't know if anyone has done this and/or noticed... but there is a really easy way to unlock all the genetic code perks if one does not have them already unlocked.

It's real easy and it works for ALL the plagues...

right when you are near the very end of humanity (death to all humans), before your plague wipes out everybody save your game (1 of each plague type), then after it kills everyone and you get your final score, simply load up the same game, play it to the end (or fwd like i do), everyone is dead, game end - final score again, then wash & repeat until you have ever genetic perk available. EASY!

that way you don't have to sit, watch, and wait til you get your hands on the good stuff

You should add, after this, you should put all your leftover points into Genetic Hardening and Reshuffle.

Dave 16 months ago

A good side note you should've added: After making the disease lethal with TOF, devolve all your transmission points and use the rest to build your Genetic Reshuffles.

Jimmy 18 months ago

I think I get the idea of this ; infect EVERYONE and don't kill them because the more lethal it is, the faster the cure will go. So if we just infect everyone and make no deaths, then at the end, with the DNA points that we stored up, we will make a symptom to DESTROY the whole world. Ain't that right Ashleign? Or am I wrong?

I had to join hubpages just so I could say thank you, Ashleigh! I was wicked frustrated when I came upon your tutorial. Followed your advise, no BS, and finally beat Bacteria on Normal in 843 days, Cure 42% complete, for a score of 9180!

Feeling grateful and inspired, I dared to try beating Bacteria on Brutal! I am tickled to report some of the messages from my Complex Brutal Bacteria:

"Ashleigh to destroy humanity"

"Ashleigh has destroyed the world despite the world's best efforts"

"Ashleigh has successfully eliminated all life on Earth"

I was in the park trying to remember your instructions, so I hope the results do you justice! It only took 1151 days and the cure was 55% complete for a score of 11150 and three bio-hazard symbols.

Now to read your tutorial on Virus! Thank you for your generosity of spirit!

Any tips for beating bacteria on mega-brutal? Ive tried this and have even tried tweaking it a little to see if it works, but haven't gotten it figured out yet. Always gets detected even if you devolve symptoms as soon as they come in. Every time I've lost because of this. Any suggestions?

Sean 2 years ago

Worked for bacteria (100% death in 894 days), but not even close with Virus. Since it costs DNA to de-evolve symptoms you don't get enough to make it lethal. Killed about 20% of world population before cured.

dj 2 years ago

I was following directions and at the end where it said infect all people and save up 100 DNA. Well I infected all people and it almost immediately stopped giving me DNA, I had 87 DNA at the time and I couldn't get anymore, so I got all the symptoms all the way up to paralysis and I was 10-20 DNA off total organ failure so, it didn't kill fast enough and they found a cure before the death toll hit 1 billion.:/

adriana 2 years ago

Followed the tutorial, but it's been stuck on 99% infected for the past 20 minutes, even with fast forwarding. :/

john 2 years ago

Worked like a charm. Cure went to 62 percent, then stopped as population dwindled.

Anlev 2 years ago

So this is pretty much about time and patience. I got infected all countries and started evolving the symptoms, big mistake. The cure came after I could get every person infected and killed. Sure, the world I left behind was not worth living, but there were people alive so it's a lost for me.

Thanks for the post, gonna try being more patience, infect every single human and then hit them hard.

Emily1515 2 years ago

Thank you sooo much!!! This made it 10X easier! :'D

Managed to complete it in 910 days with the cure at 36% (on Normal)

I found it easier to devolve all of the transmittion evolutions after it had infected everyone. This way it was a lot easier to get the DNA points at the end :)

(If my terminology is bad, sorry. I'm new to this game haha)

Problem with this walk-through and I have ran it a few times is that I don't get to achieve the 100 points in order to evolve the symptoms, I just get from 78-80 every single time. This being the case you don't get to buy total failure and so the cure does beat the plague.

In some cases coughing has gone unnoticed. I wouldn't go so far as to say it won't get noticed. Take my Necroa tutorial for example. Every time I have used it, it has been a success. Others are finding a 50% success rate. This all depends on mutations, doctor's visits and so on. Symptoms are the noticeable signs that something is wrong.

Natasha 2 years ago

Hey! Terimakasih Untuk Bantuannya :)

I've been playing this for a week, and Greenland with Iceland always make me frustrated, I didn't think to infect all of it and start to being lethal. Great tutorial it is. Now I'm at the virus chapter, and I'm confused about the DNA points to be used if you want to devolve, it makes me wonder again now.

PS: Some of my friend are playing this too, and we always exchange our strategies, but none of it worked. Glad I read yours. After all, we studied epidemic this semester, so it helps us a lot by this

Ashleign profile image

Ashleign 2 years ago from Alabama Author

I use to think that Fungus was the hardest level. It's not. I just had forgotten how hard virus actually was. Since Virus costs you points to devolve it is just a difficult level to beat. Yes in essence the tutorial is the same in theory, however, since the game is different with this level, it does take a certain amount of 'winging it'. I worked on a video last night for a tutorial on virus, however, I kept getting interruptions and I ended up getting upset with it and just quit playing. I shall try again tonight.

Stacie 2 years ago

Now this worked perfectly for bacteria on normal. Now I'm on to virus and I seemed to have read somewhere in your comments that they work the same way. Something that confused me the first time I tried this method was wait until the points are at each point like you said or buy the transmission/abilities then wait on the points. The first time around I didn't really wait on DNA point build up until I had bought everything you listed in your walkthrough because I was waiting on the rest of the world to slowly infect with my Sega disease. Now the problem I have using a virus to infect people with and using a bacteria walkthrough is it's not so easy to devolve symptoms, obviously, so that brings me back to my original question. To wait for point build up then buy or vice versa.

@Jacob, I used no DNA genes for this tutorial. It was done using the free version of the game.

@Gavin, If you find yourself without any points to build it to fatal, you have not followed the tutorial correctly. However, you can devolve transmissions and abilities after everyone is infected for some more symptom points.

gavin 2 years ago

Sure Bart.

So we have the whole world infected. You need to make sure after you follow the last evolution of abilities that you stop spending points. You don't need to try to infect them faster. Give or take you need 100 points to get to total organ failure. After a while your points will stop going up. This will stop up to about 5 or 6 minutes after you infect everyone.

I think where you are running into issues is spending additional infectivity points before the world is infected. Try to follow the tutorial exactly. I will rework it to make sure. was nice enough to make a blasthrough tutorial of this walkthrough. The video is up in the tutorial. Hope this helps.

@Kevin: Bioaerosol is the 5th combination when you Have Water 1, Water 2, and Air 1 and Air 2, it gives you a boost in infectivity.

@Jack: I am sorry for this inconvenience. Be Sure that you are devolving symptoms until everyone is infected. Once everyone is infected, you will receive a message. Paraphrased: "There are no health people left."

Then you want to evolve your symptoms to something deadly. You want to avoid anything the scientists have "Gained an Understanding of."

I went for bacterial resilience instead of heat 2 and never got air 2,

Nausea mutated when I had 99% infected but it was never detected, then I bought symptoms only, went for organ failure, then immune suppression, then went from insomnia up to Dysentery.

I use a similar tactic. I devolve all symptoms but I start in a backwoods country with no ports and planes; such as East Africa. I let the game build DNA and make the germ as infectious as I can. Birds, Rats, Insects, Sheep maxed out. Air, Water and Blood. Make it at least 1 in arid environments, and 2 in ice. But started with maxed resistances top right of 3rd menu.

This infects the whole planet, as no one is even paying attention the the Germ, although i've never noticed a random 'found'. Got lucky?

Once you have the world infected you'll have no DNA points. I let the game sit on the desk while I do other stuff and reach over for the blips on the DNA. I get 80 DNA and wham... pause game make the bug instant deathly (same one you chose) and sit back and laugh. I Devolve all the First tab and buy the hardening 1. Then as people are dying you get DNA and you buy the other harden and the 2 shuffles. and sit back and laugh as the world dies! Muahahaha

I am aware of this issue, I am currently working on the new guide. Just be patient. There was an update recently.

jo 3 years ago

Followed the guide exactly step by step. Can't get total organ failure because i have to few dna points so they cure it before all are dead. Doesent work.

Ashleign 3 years ago from Alabama Author

That's great Verm! The new update, screwed my tutorial lol, so I have been working to make it simpler over the past several days. The spontaneous detection is driving me Crazy! You guys follow me, I'll get it figured out!

Verm 3 years ago

thank you it ended up working

Ashleign profile image

Ashleign 3 years ago from Alabama Author

Updated the tutorial to make infection faster. Once you have obtained total ogran failure you can put points wherever you like, it will not matter the last cure went to 60% on my test.

Ashleign profile image

Ashleign 3 years ago from Alabama Author

You can buy other symptoms if you want, but only after total organ failure. I have checked it yet again, everything works exactly how I described it. I think the people who failed are a little too lazy.. It's okay to be lazy, just not too lazy. Try again! thanks for the comments!

Verm 3 years ago

Also should I buy all the DNA strands for making it harder to find a cure or only drug resistance

Verm 3 years ago

Should I buy other symptoms or should I buy the ones you said individually and wait or buy them together (that's what I've been doing)

Ashleign profile image

Ashleign 3 years ago from Alabama Author

Hmm.. I just did it again and I didn't have a problem.. You should not get detected at all until everyone is infected.

Vern 3 years ago

I didn't work! It was cured in 147 days!!! Everything was devolved (symptoms) everyone was infected and it ended quickly

You have to make sure to devolve all the symptoms, before everyone gets infected.

Make sure everyone in the world is infected before you attempt to kill them.
