Beating Parasite on Normal

Welcome to my tutorial on how to beat Plague Inc.'s Parasite on Normal. Parasite is similar to Virus. However, Parasite has an added feature called Symbiosis. It allows symptoms to prevent the discovery of the parasite. This helps us a lot. While Parasite is very simple in nature, I've redesigned this tutorial in order to build points fast.

Let's get started!

Quick Overview

First and foremost:

  • We will be allowing symptoms.
  • Also, symbiosis is found under abilities.

Step-by-Step Instructions

  1. Start your Parasite in South Africa, or another hot country of your choice.
  2. Build DNA Points to 30.
  3. Get Water Transmission 1.
  4. Get Water Transmission 2.
  5. Build DNA Points to 30.
  6. Get Air Transmission 1.
  7. Get Air Transmission 2.
  8. Build DNA Points to 100.
  9. Get Drug Resistance 1.
  10. Get Cold Resistance 1.
  11. Get Cold Resistance 2.
  12. Get Heat Resistance 1.
  13. Get Heat Resistance 2.
  14. Get Symbiosis 1.
  15. Get Symbiosis 2.
  16. Build DNA Points to 50.
  17. Get Drug Resistance 2.
  18. Build your DNA points until everyone is infected.
  19. Work your remaining points into the symptoms.
  20. Reach Total Organ Failure first.
  21. You can then spend any remaining points wherever you see fit.

Congratulations! You have beaten Parasite on Normal.

Almost didn't work: 98% cure; 776 days

Sally on June 10, 2020:

It worked! Thanks so much! :D

:( on May 14, 2020:

It didn’t work the first time but i will keep trying

Beans on March 26, 2020:

1163 days on brutal!

Andrew W on March 23, 2020:

The original tutorial is spot on. The only thing i did differently was to add the Neural Atrophy. It delay the cure at a steady pace

Andrew W. on March 23, 2020:

Doom Slayer, at 68 % took 588 days. Good run.

idk on March 19, 2020:

worked super ez cure 51% 913 days

ah? on March 06, 2020:

Didn't work; 3 times in a row I got discovered even without any symptoms. What did work for me was just these few modifications:

Save 30, get water 1 and 2.

Save 30, get symbiosis 1 and 2.

Save 30, get air 1 and 2.

Save ~80 get the rest as described, except don't bother with drug resist 2 since at this point you wont need it.

Save until everyone infected then go for total organ failure as described.

Do what you want with extra points.

That got me finished in 933 days with cure at 35%.

sexualchoco on February 24, 2020:

I used this idea but I upgraded symbiosis 1, and 2 first because in my previous tries it got spotted right away but did help a lot so thank you :)

G on February 17, 2020:

It does work following the guide but I did buy symbiosis 1 and 2 when i had enough then let dna build up again to get the drug res 1, cold and heat res 1&2 for both. While waiting for everyone to get infected the cure for my gameplay was going pretty fast so accordingly when it go to about 50% i invested in genetic reshuffle1and 2 that gave it enough time to infect everyone, then all points to symptoms to organ fail as more points came i just kept adding to symptoms. 922 days and 56% cure in the end.

michael on February 10, 2020:

Almost didn't work, the cure got to 94% but I started getting heaps of oints and bought 3 genetic reshuffles. thx

Awais on February 04, 2020:

Worked perfectly. You just have to be patient while it infects the whole world and save at least 70 points to achieve required symptoms.

Gabriel on December 31, 2019:

It worked perfectly with 953 days, and 74% cure

Some people say that the cure was released early, that’s true. Also, some people still make the mistake of doing the total organ failure thing but the world is not yet fully infected. You should wait for it to fully take over the world, and do the total organ failure thing.

Also what I did to beat the game, I was in the total organ failure thing, I realized that I didn’t have enough DNA points to buy “Total Organ Failure”, so I devolved all, and bought it, and I still won the game!

Come on, listen to the instructions, don’t rush.

Chrisie on December 12, 2019:

Worked perfect, 722 days, 48% cure

GamerHacker on November 02, 2019:

Didn't work, cure was released

E on October 27, 2019:

Didn't work killed half of humanity

Empty^liz on September 23, 2019:

Thx brother, it worked

Crap game on September 17, 2019:

Followed to the letter, did not work.

Thanks

Hi on May 23, 2019:

I recommend to get symbiosis first because they can still find out about the disease. Still worked :)

Flerovium on May 19, 2019:

The Last Country i infected was Sweden. Licky me

Name on April 02, 2019:

I would personally

Get Symbiosis 1.

Get Symbiosis 2.

Maybe even 3 before having any resistances but then I didn't save till I could buy them all

Nickname on March 29, 2019:

i tried twice but the first time they didn't die fast enough after being infected and the second time the infection didn't spread fast enough

warpaint408 on February 17, 2019:

This was so easy to follow had no trouble at all! Done in 667 days with only 30% cure complete. 19,640 points! Thank you!!

Demig0d on February 15, 2019:

Once again your tutorial has surpassed my expectations i was able to beat brutal with these stats 943 days 59% cure and and score of 13740

Someone on January 20, 2019:

It worked, until the end. I didn't have enough to get to Total Organ Failure, the cure was too fast. Any way to stall for more DNA?

Huwar on December 27, 2018:

1023 days 79% cure I had to get the DNA looking things to throw the cure back to around 60-65 percentage (%) Otherwise cure would have won! :D Thanks for carrying me through the whole game! I don't have many things left now. As said above thanks. These must be very hard to make, VV as said below too Thanks for your efforts put into this webpage/walkthrough. Really helps.

Pradhuman on November 21, 2018:

Thanks for your efforts

11fastgamer on August 22, 2018:

worked for me, but got halfway spotted. so i did genetic reshuffle 1 and i killed evryone

Veronica on July 09, 2018:

I switched it up a bit. I won the game by devolving any mutations until everyone was infected. Instead of using points on transmission, I evolved all three symbiosis first, early in the game. As long as you make sure every last human is infected before any symptoms are evolved, you should be good. Aim for total organ failure and coma. Oh and make sure you use drug resistance and genetic hardening.

John on April 27, 2018:

I just want to say. this is also very effective on brutal as well. helped me out both times. keep up the good work

Natasha on February 11, 2018:

Thank you again! Followed. 51% cured. Started in Saudi Arabia only change.

M on December 29, 2017:

Did everything it said and went fine.

Thanatos on December 22, 2017:

Did it already 2 times and no results. Disease was caught really soon and the cure was really advanced at a certain point. Only got to kill 1B people and 2,3B at both tries. But hey, still gonna try as many as needed. The hardest one by now.

Mitchel on December 07, 2017:

Placed Symbiosis before transmission this is better to stay in stealth. Infected everyone and yhey didn't notice my disease.

aris on August 14, 2017:

I don't like when you kill over 7b and don't win.

Someone on August 11, 2017:

The symbiosis needs to be placed more or less first, i'm always detected midway through the part where I need to save up to 100 points

Parasite on August 03, 2017:

719 days 68% cure,

the symbiosis does nothing, I upgraded it to max early on and it still got detected easily.

Me on July 28, 2017:

Symbiosis needs to take more of an early priority. With this walkthrough, it gets noticed and a cure started too quickly. They complete the cure right about the time you're able to progress to multi organ failure. Level 3 symbiosis early on, even before climate resistance made a MASSIVE difference. I was killing them off well before they ever noticed the disease.

Greg on July 19, 2017:

As long as you just keep devolving all symptoms until everyone is infected, you can win. Once everyone is infected, put points into the symptoms and watch the world die.

Alex on July 07, 2017:

756 days and 66% cure

AndrewGaming on June 12, 2017:

Mostly, you must have to develope the Drug Resis, Genetic Reshuffle, and more to keep the scientist working. You can also develope Paranoia to make countries don''t work with the cure

Angus on June 12, 2017:

Thanks, this works well

orteam on May 28, 2017:

Worked :)

Ana on May 19, 2017:

794 days 48% cure! Another tutorial that woks but I change some things at the end. I devolved transmission and heat and cold resistance and also evolved drug resistance several times otherwise they would cure me

Kyoki on May 18, 2017:

Started in india and it was so much better

Ra on May 01, 2017:

THIS DOESNT WORK I DO IT 5 TIMES!

I FOLOW YOUR INSCRUCTES AND THEY ALWAYS LEFT OR CURE IS READY

Samantha on April 30, 2017:

987 days. 62% cure. Victory!

Ry on February 11, 2017:

I tried it once your way with letting the symptoms go however they pleased and they started developing a cure by the time 20% of the world was in infected and I failed by the time half the world was infected then I ran it again and de evolved all the symptoms that went nuts and i beat it

Anonymous on January 13, 2017:

I named mine shitface!

Anonymouse on January 02, 2017:

Its all about making them crazy and think there's really nothing wrong while they are actually infected and dying quickly.

Jen Anderson on January 02, 2017:

This worked for me; 980 days and 70% cure. I would also recommend using DNA points for genetic hardening and reshuffles, as others have said. Thanks!

Me on December 26, 2016:

Didn't work. Have to upgrade sheep transmission and sterile transmission.

Kaz on December 20, 2016:

This doesn't work....only way it does is to add genetic hardening and a couple of genetic re shuffles

Mystery on December 06, 2016:

srry didn't work I try about 3 times

Rozack on November 06, 2016:

48% Cure 643 Days Total Score:11940

Jake on October 22, 2016:

This doesn't work at all on multiplayer.

a random dude on October 12, 2016:

Als go down from rash. Fairly deadly upgrade there.

Jerod Hawkins on July 25, 2016:

I recommend using your extra points for genetic hardning and reshuffles

Ashleign (author) on July 11, 2016:

Just did an update video on these tutorials check them out at www.youtube.com/chillbillysauce

Y on July 10, 2016:

99% cure.... close call, but made it.

Rob on July 05, 2016:

Marry me?

Death on June 15, 2016:

51% cure, 841 days

MaxWasy on May 24, 2016:

Good but took a long time

Emma on March 27, 2016:

Used this on brutal. 807 days.

Paula on March 12, 2016:

it worked for me, but I reached 99% and then I finally reached enough DNA-points for a genetic reshuffle.

Mr. It on March 08, 2016:

Towards the end I had to make some adjustments to complete the level, but aside from that, this works.

Justin hunt on March 03, 2016:

Worked well for besides it almost going to 95%

Morriganna on February 29, 2016:

If you do symbiosis earlier on it is extremely more effective

Papyrus on February 08, 2016:

Worked! but i din't follow esacly i worked to the organ failure from coughing

and Worked!

42ndsheep on December 03, 2015:

did not work, to fix: before you go for total organ failure (I didn't even get to it for a really long time and would recommend going there from coughing) get your points to 100, also devolve all symptoms until u infect everyone in the world

Hitman on December 01, 2015:

The first time I tried this, I followed everything step by step and "Shit" got detected to early and I lost, with Greenland infected but majorly healthy. Immediately after that I decided to try my own method. Firstly, start in a hot country, so that all other hot countries con be infected in due time. Please note that using this method you'll have to play in fast forward, as you'll usually win in 900 days or more depending on how fast you evolve things. By the way, in the beginning, if you have unlocked the gene for bonus DNA when devolving, then use it. This'll make things easier later in the game. Wait till you get like 50 DNA points, then completely evolve the symbiosis to level 3. This will ensure that your parasite will not be detected, and then get Air 1 & 2, Water 1 and if you have any points left and you can afford it, Drug Resistance 1. Then your parasite could mutate a few symptoms, but don't bother. Now wait till you get 50 or more DNA points so that you can get Drug Resistance 2 and Genetic Hardening 1. Now keep in mind that you should NOT evolve ANY symptoms as it'll lead to either people dying faster or your parasite getting detected faster. Devolve any lethal symptom if it mutates. Now save up your DNA points till you infect everyone in the world or the message "There are no more healthy people left in the world" pops up. Now your main objective is to get to Total Organ Failure first. This will ensure that people die fast. After getting enough DNA points get Necrosis and Hemorrhagic Shock. Now the death rate skyrockets, and you'll have a steady income of DNA points. Now get All of the Genetic Reshuffle (1,2 and 3). Now all you need to do is sit back and watch the chaos. Congratulations! You've beaten Parasite on Normal!

If this doesn't work please get back to me. I'll then work up another strategy.

Mokona on November 15, 2015:

Nice tutorial! I started in Africa and it has worked!! Thank you ;)

Foullily on October 19, 2015:

It almost got me, but without symbiosis 3 and a few more drug resistances while everyone was being killed by TOF i woulda lost. However, its a good walkthrough otherwise, just a few tweaks or quick thinking on the players part :3

Thank you

Higherlevel1 on October 07, 2015:

They cure it before i can infect everyone i think allowing symptoms early on is doing it going to try again can u please update

TRex on August 23, 2015:

Nice tutorial but unfortunately it didn't work for me. Greenland was last and slowest to get infected and the cure went super fast. I'm going to try this but fully evolve symbiosis to see what happens.

Thanks!

Nagrom on July 10, 2015:

I did like your tutorial but I just didn't work for me, so I tried it out on my own and I did good. All you really have to do is evolve all three of the symbiosis,

water resistance(to the maximum)

air transmission(to the maximum)

cold and heat resistance all the way. Devolve your symptoms until everyone in the world is sick, after that evoke your symptoms until you reach Total Organ Failure . It's how I won. But I still love you and your tutorials, honestly

allie. on June 25, 2015:

I'm a big fan of your work but I've done this one 6 times and it hasn't worked.

Please help..

wat on June 19, 2015:

That may have been my fault for naming it "Twerking" ... as soon as it was discovered, the world was quite eager to eradicate it.

Apparently I don't learn, because my next attempt was "YOLO" and that was spontaneously detected and destroyed with extreme prejudice as well.

Let's see how "Swag" does...

wat on June 18, 2015:

Spontaneously discovered during step 5, without any symptoms. That didn't go well.

(: on May 31, 2015:

i don't know what i dis wrong but i had no symptoms and people were treating my disease like it was really deadly lol but the cure was complete before everyone got infected ):

Flutter on May 30, 2015:

This tutorial only works about 30% of the time. The scientists will almost instantly find the disease.

Ray on April 13, 2015:

Should I devolve the transmissions and abilities once everyone's infected?

Lrxx on April 10, 2015:

Darn, only 15,000 survived in Greenland. Got it infected but in the end some of them survived. Gonna try again, thanks for your tutorial though!

Josh on April 05, 2015:

Im struggling to complete it, ive played a few times with these exacy instructions but they keep finding the parasite really early and curing it :P

Liam on March 30, 2015:

This Works. But my computer forces to shut down immediately but i will try again. I force to evolve an parasite's abilites because of a high severity. Nice Tutorial.

Braydeng71 on February 26, 2015:

DNA sequence : Standard

Difficulty: Normal

Time: 1062 Days

Cure progress: 69% complete

Thanks for the tutorial! Did I do good?

cindy on January 22, 2015:

have you done or will you do brutal and mega tutotials?

Ashleign (author) on January 20, 2015:

Or Sir.. Doesn't matter.

Zalel on January 19, 2015:

Perfect! Thank you uhhh maam?

Ashleign (author) on January 16, 2015:

I'm not sure. I will check, I don't have it on my phone anymore.

0897867564 on January 15, 2015:

There is no symbiosis on the cell phone version. Ignore?

wawawaifus on January 10, 2015:

But I still won

wawawaifus on January 10, 2015:

Not enough DNA points

Lolcraft on January 05, 2015:

You can actually go without drug resistance 2. It'll take longer but you can kill a lot faster though.

meggan on January 04, 2015:

Mutations?

August on December 28, 2014:

So I followed this exactly, but the parasite was noticed, and the cure beat me. Is this normal?

Tristan on December 21, 2014:

I would like to say that you make very good tutorials but I would buy symbiosis 1 and 2 in the bwgging because I had a problem with it getting noticed when it had no symptoms and no way to get noticed

JoMoFo on November 15, 2014:

Worked great! And in only 798 days :D

irishjay91 on November 13, 2014:

used your tutorial on fungus and it helped me extremely and using this tutorial on parasite haven't been discovered yet and its my first try thanks for your help
