How to Beat Plague Inc. Parasite on Normal

Updated on March 11, 2015

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 recently in order to build points fast.

Let's get started!

First and foremost:

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


  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 beat Parasite on Normal.

There, I drove the ambulance mostly, but I can say that I was in the room while a life was actually being saved—that was a cool thing to see. Bless our troops, fire, police, and EMS workers they have an incredibly hard job, and I love them with every bit of my heart. Especially the police.

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

      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 3 weeks ago

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

    • Kaz 4 weeks ago

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

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

    • Mr. It 10 months ago

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

    • Justin hunt 10 months ago

      Worked well for besides it almost going to 95%

    • Morriganna 10 months ago

      If you do symbiosis earlier on it is extremely more effective

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

      and Worked!

    • 42ndsheep 13 months ago

      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 13 months ago

      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 14 months ago

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

    • Fungus Amoungus 15 months ago

      i followed the tutorial VERY presice, and they quickly discovered and destroyed me. either this game hates me, or their is a flaw in the tutorial.

    • Foullily 15 months ago

      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 profile image

      Higherlevel1 15 months ago

      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 17 months ago

      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 18 months ago

      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. 19 months ago

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

      Please help..

    • wat 19 months ago

      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 19 months ago

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

    • (: 19 months ago

      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 19 months ago

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

    • Ray 21 months ago

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

    • Lrxx 21 months ago

      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 21 months ago

      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 21 months ago

      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.

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

      But I still won

    • wawawaifus 2 years ago

      Not enough DNA points

    • Lolcraft 2 years ago

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

    • meggan 2 years ago

      Mutations?

    • August 2 years ago

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

    • Tristan 2 years ago

      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

      Thank you SOOOOO much for your tutorials! This one definitely helped me, although I tweaked it a little bit. I had to use Symbiosis sooner than you've listed because my parasite kept mutating and giving me symptoms. I know you said to allow symptoms, but I had to devolve them for a while due to continually being "discovered" too early and then the cure would start, but not enough DNA points came around after that for me to counter it...and the cure was going FAST.

      But once I did that...DNA points popped up quickly. I waited until everyone was infected and then unleashed terror. I owe it to your tutorial to be sure!

      DNA sequence : Complex

      Difficulty: Normal

      Time: 897 Days

      Hey,

      Every step went extremely well. In this level it was much more easier to gain DNA points. Amazing tutorials, keep it up!

      Try Simian Flu before you check out my tutorial.. There's some serious challenge there.. Although it only took me a full day to figure out a solid tutorial for it.

    • Misdrhaal 2 years ago

      Difficulty : Normal

      Day : 920

      Score : 38220

      Cure : 14%

      Investments to counter the cure : 0 point

      I started in Russia, stacked points to up one level in each type of contamination triggering mutation, then maxed out the air and water spreading.

      And then waited, waited, waited, undoing every new symptom. Then the message indicating that the whole world was infected poped up. (about 800 days)

      So i've unleashed hell with more than 130 DNA points (and more coming the weeks after^^)

      They started the cure juste after the first symptoms, but that was too late, definitely. The diseases killed everyone in a blink of an eye:p

      And it seems to be an always win strategy? Quite a shame for the moment, i will try prion.

      You rock, girl. Thanks a load for the tutorials. I love the game but in was getting spoon frustrated!

      And I think with your mini-bio that you're an amazing person with a deep heart, and I want to say that even your short summary touched my heart, and I can admire the part of you that you display to us.

      Once again, thanks, and happy gaming! :D
