How to Beat Plague Inc. Necroa Virus on Normal

Updated on April 13, 2016

Beating the Necroa Virus

The Necroa Virus is a strange level—it is unlike any other level of Plague Inc. It does take a certain amount of skill. Make sure that you watch my video below or follow the steps exactly as listed. Also, I cannot stress enough that this tutorial was written for the paid version of Plague Inc. In other words, I highly recommend shelling out the two or three bucks needed to buy this game. IN this case, if not just to use Creationist Gene alone. Trust me, you'll need it and it'll be well worth it.

Before we dive in, here are the Genetic Codes I used for this tutorial:

  • Metabolic Hijack
  • Creationist (as mentioned, for the best results, you will need this genetic code.)
  • Aerocyte
  • Xerophile

Phase 1: Infect Them

(I started my plague in Saudi Arabia.)

  1. Build your DNA points to 15. Transmissions: Blood 1.
  2. Build your DNA points to 15. Transmissions: Saliva 1, Air 1.
  3. Build your DNA points to 20. Transmissions: Gastrointestinal Expansion. Saliva 2.
  4. Build your DNA points to 20. Abilities: Cold Resistance 1, Cold Resistance 2.
  5. Build your DNA points to 21. Transmissions: Water 1; Abilities: Drug Resistance 1.
  6. Build your DNA points until everyone is infected. This should be around 60-62 points. If you do not have that many, you will want that many so just keep building.

Phase 2: Zombie Mode

Note: You should have around 60-65 points before you start this phase.


  • Insomnia
  • Fever
  • Photophobia
  • Delirium
  • Cytopathic Reanimation
  • Anaerobic Resuscitation

  1. Pop Cure Bubbles.
  2. Build your DNA points to 20. Abilities: Autolytic Delay.
  3. Build your DNA points to 30. Symptoms: Psychosis.
  4. Build your DNA points to 30. Symptoms: Acute Encephalitis.
  5. Build your DNA points to 30. Abilities: Putrefactive Resistance; Symptoms: Enhanced Sensory Integration.
  6. Build your DNA points to 30. Symptoms: Adrenal Surge, Enhanced Motor Control.
  7. Build your DNA points to 20. Symptoms: Hyperosmia.
  8. Build your DNA points to 30. Symptoms: Peptide Surge.
  9. Build your DNA points to 20. Symptoms: Acidic Reflux.

      Wow, for once your tutorial doesn't work. Surprising.

    • Nobidy 13 days ago

      it would be helpful if there's genes you can list

    • Anon 2 weeks ago

      I can't reach Phase 2 because there are symptoms that randomly mutate before I infected everyone.

    • Eric 2 weeks ago

      All of this tutorials work for me on brutal

    • Don 3 weeks ago

      Hello. This had not worked for me at all. I DID in fact use the Creationist gene and still Zcom destroyed everything. I followed every step carefully. Though I did not have Teracyte or the other thing, I did have Creationist and Xerophile. What happened was that the disease mutated anyway, despite Creationist holding it back. What do I do now?

    • Ted 7 weeks ago

      Should I devolve symptoms? I don't have Creationist

      Should I devolve symptoms? I don't have Creationist

    • Sp00vaFox 7 weeks ago

      I have been playing Plague Evolved on my YouTube channel. And ended uploading a video or two failing miserably on the Necroa. I looked to JackSepticEye's channel for a few tips. I must have played the Necroa Virus more than a dozen times and nearly winning on almost all of them. Yours is the first walkthrough I looked at - and it worked!

      It took me half the time to win too. I used almost all of the genes I unlocked so far: Creationist, Teracyte, and Xerophile. I don't even remember how far into the cure it was, but I got a three star score and 15,230 points. ^_^ Thank you so much, Ashleign.

      I wonder if I could try it on Brutal. I've only used Normal.

    • Cody Haas 7 weeks ago

      This guide definitely did help, I didn't have the automatic popping of bubbles on, but I did have bonus DNA on Orange bubbles.

      Guide is awesome except that you essentially NEED the Creationist Gene activated. Without it this guide failed miserably in the face of Z-Com, because I had to start early on the zombie phase with way fewer points. However, using that gene I had 80 points before I even had everyone infected and from there Z-Com was not able to expand. I recommend grinding out Neurax Worms on Casual to get the gene. (I am on a console version of the game)

    • agreee 8 weeks ago

      no, it didnt worked.

    • Roks 2 months ago

      Didn't work. just wiped all the Z's in it's initial country and then moved on to clear other.

    • Ashleign profile image

      Well actually, you will need to beat most of the levels on normal in order to progress through the game. I rather enjoy the game design due to the fact, my tutorials have now, over 5 million views. That's why I did all the tutorials on normal. Necroa is by far one of the more challenging levels. However if you scan through the comments, some have done different strategies without using the creationist gene. Even myself, I did it without the creationist. However most of those times much of the game was left to chance. I was trying to prevent the crisis of it not working for everyone, and quite frankly, it still doesn't work for everyone because people won't follow precise instructions, but what can you do?

    • Zombinator 2 months ago

      Worked on Brutal

    • Jay 2 months ago

      I'm sure this will work, but it sucks that beating this on NORMAL mode requires such a specific set of genetic codes. Creationist is damn near mandatory and woe betide the player who hasn't unlocked it yet. (FFS how many games on Casual will it take to unlock the one code that allows you to progress past Necroa Virus? Ridiculous game design.)

      Thank you for the comment. Hopefully it helps some of those that haven't found success with this tutorial!

    • Shanz 2 months ago

      The best way to win this game is to begin in europe, with darwinist, and to get some transmitions but no medicine resistance and not too much transmition because you really want your infected number in each country to remain low, because next you get some non lethal symptoms to improve your severity and get more DNA when you reach new countries.

      This will allow your infected more time to spread out on the others surrounding rich countries while still keeping their relative numbers low. Then, after some time, your disese will start spreading to eastern europe or Africa, and this is when you get medicine resistance. All of a sudden, you will have most of europe infected totaly infected and about half the world already lowly infected. You slowly bring up the symptoms to the point where you can make zombies, and you do it before the cure can be cast of course.

      Now, when Zcom arrives, you don't care about it. Take the capacities to send hordes from one country to another at maximum strengh. Take every country not defended by Z com in an order do the furthest from Z com are destroyed first and the nearest last. Surround their base and send 2-3 hordes from a country that has more than 20 million zombies into it at the same time in Zcom base.

      I highly recommend you do not spend to much DNA on improving your zombie abilities or symptoms. Also, i highly recommend you use darwinist, so you can have free improvements of symptoms.

    • Ashleign profile image

      Ashleign 2 months ago from Alabama

      Can you explain a little bit more? ZCom is not a factor when I run this tutorial. Can you be a little more specific?

    • OwO 2 months ago

      Tested and does not work. This tactic fails to take into account of Z-Com.

    • IC50 2 months ago

      I didn't get any mutations and I was able to get the hard-to-reach countries, but I still got cured at an alarming rate way before everyone was infected. Bad luck or something?

    • Ashleign profile image

      Ashleign 2 months ago from Alabama

      I am sorry that you have had bad luck with it. The collective has had much success. I would suggest you find a strategy for your own play style if this doesn't work for you.

    • Zmig 3 months ago

      BS man, i dont know HOW THE HELL this worked for any1 alive, but 1, you didnt make it clear if we should devolve mutations, 2 how the hell are we supposed to infect Russia, Canada, Greenlands...? I did Exactly, copy pasted, everything (and every guide you have worked so far) and i failed miserebly/

    • Totally Not a Zombie 4 months ago

    • Hypatia 5 months ago

      Wow! This was phenomenal, thank you! I followed your tutorial exactly. Defeated the game in 1197 days(i waited a little bit long to get 64 points), cure was at 25%. I had to devolve only once. My game was on my laptop, it might be different on tablet though. :) thanks man! Now I can move on to my new plague... ^^

    • FiendishCatz 5 months ago

      Everyone, the reason this isn't working for you is because you're not using the Creationist gene. The beginning clearly states that it is best to use Creationist. So just keep beating more games until you can get it.

    • Ace 5 months ago

      Do we devolve symptoms?

    • CRYS 6 months ago

      This guide actually helped me defeat brutal stage and i've been trying to beat this on brutal for about 2 weeks lol smh

    • Brynt 6 months ago

      if you start in Greenland then you will not have to worry about failing to infect it. Saudi Arabia is a big travel hub so it gets infected pretty quickly. took me little longer than I would have liked but once everyone got infected even if the zombies didnt kill them they still died.

    • Missy Fitch profile image

      Missy Fitch 8 months ago

      didn't work for me. but what did was Metobolic jump, the rest i used were the same. I did saliva 1 and water 1, Blood 1 and air 1, then Drug resistance and cold 1 and 2. Then i let it build till everyone was infected. then i went down the right side until i got to the zombie infection, then i used every available to make the zombies as bad a possible. only going to the abilities to upgrade the length of time it took them to decay.

    • guest_user 8 months ago

      done in 575 days! thanx!

    • Kreutzfelt 8 months ago

      this simply doesnt work

      at some point my plague mutates, and they start the cure, sweden, greenland or canada becomes unstoppable. i kill most of the world, and are left with those three, no matter what i try i lose.

      so i wont recommend this tact

    • Anoyed 9 months ago

      Flat out doesn't work, random evolutions happen way to often usually well before you've infected everyone. It doesn't matter how many zombies are in a country, even if it's millions, as soon as Zcom shows up they are gone and the game is over. I lost FASTER with this then normally.

    • Atomic-Leader 10 months ago

      It worked, and it had exactly 1242 days, like you had Ashleign.

      Wow! Been at it for days, trying to figure it out. This one won it for me first try, only change I made is I took Aquacyte instead of Aerocyte. Cure 79%! Had to devolve once.

      Thank you so much!

    • Dave 10 months ago

      This worked beautifully. While the cure was 100%, I beat the world in 1123 days. I've been working for a long time to beat this. Thank you!

      works like a dream thank!

    • Care 12 months ago

      This does work if you make one alteration--use metabolic jump (cytochrome surge works too, but I got a bit more points from metabolic jump). DO NOT use metabolic highjack. Doing this, you will have enough points to complete the rest of this walk through successfully. The only exception being if you are unlucky (using the creationist gene) and get a premature evolution of symptoms. You could still win, but it will be more difficult, and it could go either way. However, unlike most games, you can have a 100% cure and still win.

    • Azshara 14 months ago

      Tried this many times (about 15) with this strat, failed each time, infecting greenland is what's causing the issue, it takes to long and by the time it's infected the cure is already at 70+%.

    • sarmalac 15 months ago

      I was having huge trouble with Necroa. Tried this strategy and it worked like a charm. The cure percentage got up to about 88%, and the humans did start one Z-Com base, but by that point it was too late for them and they never managed to get on top of the threat.

    • Jordy 15 months ago


      My lazy arshole zombies have the ability to cross to adjacent isles as stated in my upgrade tree.. Only things is.. They dont!!-_-

      I can drag hordes across the bloody world but getting to new zealand gets me an EEE buzz, it does not light up either, in other words, i can't EVER send hordes to say greenland.. For reasons unknown, this is seriously frustrating..

      I'm playing this on mobile, could they have nerft the ability?? Anyway wtf

      Please help me if possible

    • 16 months ago

      Didnt work

    • Goatfish 18 months ago

      I did as you said but failed. So I slightly changed the genes:

      - Replaced Aerocite with Aquacite (cause Greenland is a bitch to infect)

      - Replaced Metabolic Hijack with ATP Boost (for a better head-start)

      I was able to buy first transmission straight away and somehow I had a lot of orange bubbles so I managed to infect the entire world without being noticed (tough with 50 something DNA. I won in 910 days with the cure at 89%.

    • Lance 19 months ago

      The first try, I got everybody infected before any symptoms mutated, but the cure reached 100% before I could kill everyone.

      The second try, despite using the exact genetic codes you did, Hypersalivation mutated before everybody was infected. I then just got super aggressive and would have won, if not for the half dozen Z-com bases.

      The third try, your directions did get everybody sick before any mutations arose. I saved, and then I strayed from your directions a bit and ONLY bought symptoms, the more aggressive, the better. The cure still got into the 90s, but the zombies crushed the base and killed everybody before dying off themselves. GRAINS was victorious.

      I really appreciate your tutorials. I just think Necroa has some variability that's tough to combat with a cookie cutter guide.

    • Savis 19 months ago

      Thanks for the tutorial. I followed everything exactly and did beat it although the cure rate got way up to 91% for some reason.

    • Cryowolf 19 months ago

      i don't understand the mentality of this game sometimes. in virus, people are puking, crapping a lot, devolping cysts and all sorts of ugly things and it goes for awhile before the world cares. in this one, ONE person starts drooling and it's "WE'RE ALL GOING TO DIE!!!" .. da fuq?

    • CollegeGamerGrl profile image

      CollegeGamerGrl 20 months ago

      So I've tried this like 10 times, and every time I start to evolve symptoms, the cure increases so rapidly that I can't win. I have the right genes on and everything!

    • Robz 20 months ago

      @John. my assumption is that there is a little difference between this tutorial using pc and us using mobile phone. for me, it will still happens once or twice. just devolve them and in my case i still get 60-70pts to unleash the zombie. in my case there are more problems:

      - the cure goes on fast despite the zombie out break. i counter this by saving some dna points and use genetic reshuffle when the cure is about 90% and a good portion of the world are destroyed.

      - after i foil the cure, zombies in some countries die out way too quickly before killing/converting enough people. you have to keep raising zombies every time you get 5 dna points (make sure you evolve regenerative activation before hand). raising zombie in a country can be done by dragging the 'hand' symbol on the bottom of the screen to the troubled country (u can do that to a country that have z com base too). just a little warning, this process gives more boredom than watching paint dry.

    • John 21 months ago

      With creationist you shouldn't have any mutations? Yeah right. Last 2 times I did this tutorial I got a symptom at the end before I infected everyone which allowed the scientists to make the cure. What is happening? Am I doing something wrong? Or is it just bad luck?

    • meow mix 22 months ago

      It still works, worked for me.

    • Grymm 22 months ago

      Yeah if you look at his video he's not getting any borders shut off and the cure doesn't start until hes effectively infected the whole map. When I do this though borders are being shut down and the cure is at 16 % before I can get enough points to start the zombie process. Think they patched something that makes this guide obsolete

    • Ember Heart profile image

      Ember Heart 22 months ago

      I just can't do it. I do it EXACTLY the way you do it, with the SAME genes, and about 5 seconds after getting the upgrade to Anaerobic Resuscitation, the cure is already at 15%. Wtf?

      I owe you such an apology. A few months back I tried this for hours on end, maybe over a few days, and it just wouldn't work. Random mutations, etc. ALways blew up.

      Today, no random muts. (Still no metabolic jump.) I beat the game before I was 80% done with the guide. Total Victory.

      Thank you, and sorry again.

      Hey ChillBilly (with tits of course),

      Thank you for the great tutorials. I don't think I would have ever gotten past some of the levels without them. They are awesome!

      For some reason, I cannot get this one to work though. I follow the instructions to the letter and every time the cure rushes ahead and destroys all my great plans for a zombie apocalypse. I don't have the metabolic hijack gene and the aerocyte gene, but can that make so big of a difference that I get my butt handed to me every time I try?

      Hugs from Denmark

    • sarah 24 months ago

      I followed your exact directions but came across a problem. By the time the world was completely infected I only had 47 points so I couldn't get the next group of symptoms fast enough to beat zcom. I'm going to try again now with my own tweek now that I see the strategy. But it was impossible for me to "wait for 60-65" because once everyone was infected there were no more DNA points coming. Thanks for the strategy though. I was lost as to how to beat this one!

    • Samo 24 months ago

      If you bought the game on Steam and don't have the Creationist Gene unlocked:

      1. Play a round in Normal using your favorite type.

      2. At the very end, just before the last person is dead, SAVE your game.

      3. LOAD that game and finish it again. Each time you do finish on Normal, a gene gets unlocked.

    • Cvwtd71 2 years ago

      Go slower with the transmissions than I did and see if that helps.

    • Danyal Mohammad 2 years ago

      The problem is, even with creationist, the symptoms mutate sometimes, which sets back almost 10 per evolution. I stuck with the whole world infected, but only 40 dna points because of the mutations.

    • Sirius 2 years ago

      5054 days oh and 97% the cure stopped, epic win

    • Gamerlady 2 years ago

      I had some problems beating the level by following the tutorial step by step; however, I used the Cytochrome Surge, and it worked. I didn't get a really high score, but I managed to win.

      Btw... I use your tutorials when I'm stuck to kinda get a feel for how to beat the level, and then come up with variations. For the folks complaining that these don't work; use the tutorials as a guide, but change things up a bit (except for the creationist gene) to find what works for you.

    • Jason 2 years ago

      I just downloaded the game for my Tablet. I noticed the computer version looks a lot more easier to play. But at the same time I wonder if it plays out differently then on the computer version he is showing. Only because there is a cure always started halfway through the spreading before any symptoms are randomly popped up or if you choose them.

    • Brian 2 years ago

      I beat this level in 550 days with score of 8020 and cure progress at 71%

      Followed your instructions exactly and the cure was just too quick... dunno if they didn't fix anything

    • That Guy 2 years ago

      Followed exactly but didn't get it even after a few tries. no hard feelings however. nothing goes exactly the same twice and just like in simian flu the research bases/z com bases are the annoying parts. but hey. if you can come up with alternative routes to the winning circle then maybe I could try that. I don't really care about stars or anything.... and the fact that the game + genes + dlc's + whatever else you have a mind to purchase actually can cost more/less in some countrys/devices so not everyone will have the genes... but I do so I don't rly care :P anyway, thanks for the tutorial even if it didn't work, and sorry about the long comment :D

      thanks a lot,

      Thank you so much! This was indeed an incredibly aggravating plague to use effectively.

      I had no problems! This guide was perfect. And yes, that gene is key. I can't seem to win without it. Got over 100k points with this strategy and under 1200 days. I tried several times on my own and failed, then won the first game using this guide :)

    • Sull 2 years ago

      Sorry i have to put this way, your guide has to be more detailed. the game has random events and chances to mutate, every single time i tried your "guide", right before i can hit 60-65 dna, i get mutation. rework this

    • yabig 2 years ago

      Got it first try with your tutorial but it took FOREVER to unlock the Creationist gene for whatever reason. It gave me everything except what I wanted (Ugh!). Thanks a bunch!

    • Frog 2 years ago

      Thank you for the awesome tutorial!! I have tried it so many times on my own, and it finally worked following your steps precisely. The mutations killed me several times, and I had to just start over when they came up too early. If I devolved more than 1, I didn't have eough points for the next stage. And, that is using creationist. Crazy, but fun game!

      I never delete comments. This does work.

    • DoesNotWork 2 years ago

      You need to update everything. The game has been severely patched. Stop deleting comments that tell you so because they are true.

    • Dementophobia 2 years ago

      I managed to beat normal with your guide, although I got a mutation early on. I devolved it but was lucky to get another mutation (Insomnia) a few days before I went into the zombie phase. I lost some important DNA points because of this but still won with the cure research around 90%.

      So for all of you who get an early mutation despite using the creationist gene - It should be fine to devolve it once, as long as you get Insomnia as a second mutation for free when you need it.

      Without creationist this strategy simply does not work. Unlock it or try a different approach to beat this level.

      I use Creationist but every time I got one mutation and I follow exactly the tutorial and I fial every time because of the mutation ):

    • Filip 2 years ago

      I have a question. What should I do with mutated symptoms? Do I leave them be or do I devolve them as fast as possible?

      Another great walkthrough. Anybody managed to do this without 'Creationist'?

    • TheCockroach 2 years ago

      Managed to beat it faster then you did, by following your directions almost exactly. Only one difference.So many zombie bubbles kept popping up, that I had almost twice the recommended points for the next section, so I managed to do 2-3 sections at once. This was actually my first 4-star level also. Screenie below.

      And I just realized it's called ZCom. lol

    • bundat 2 years ago

      I used to hate necroa virus, now its the only thing I play, on mega brutal.

      The thing to realize about it is that it is that, when zombies start, there are no more "infected".

      You will literally see a population of hundreds of millions invaded by zombies, and after awhile, there are only zombies and healthy people, no infected ones.

      Thus, increasing infectivity, like by transmissions, or even lethality, is all worthless and a waste of DNA. You're not supposed to play it like Plague Inc. AT ALL.

      In fact, just sending in a single horde of millions of zombies usually instantly collapses a non-XCom fully healthy country into nothing but zombies.

      What I do is make a beeline to get the zombie symptom right away, then go straight for horde movement. If you have a high severity, you can get tons of DNA for invading a country.

      Then you can just keep invading the country next to you continuously, very quickly. Click the red bubble and you'll have DNA to invade the next. The entire game becomes a battle against XCom.

      You just want the ability that makes your horde millions of zombies strong, then overwhelm XCom bases with hordes and hordes of millions and millions of zombies. And they will keep fighting, so all symptoms and abilities that increase combat ability really help.

      It's really fun played this way, it's a very active "war" game, where you keep sending millions of troops to destroy militarized XCom countries.

      I can consistently beat Mega Brutal this way, its a blast.

      Thank you for the tutorial Ashleign, I've honestly tried 20-30 times to beat Necroa with no luck. First time with your tutorial it worked.

      The problem with Necroa, it changes each time. This tutorial does work, it just depends on your game.. I am working on a cookie cutter tutorial.. They aren't as easy to come up with as you might imagine.

    • Shikyo 2 years ago

      Even with your genes, it developed a symptom before 100% infected. Following your guide to the tee, in the colder countries (mostly greenland, and canada) i only infect roughly 200 people per day. With ~35 million people in canada, its taking quite a while.... have another 500k people to infect and the cures at 49%... and that's with getting the extra abilities genetic hardening & reshuffle...

      Thanks for this, it worked beautifully. I didn't even need to evolve Acidic Reflux. Final score: 55,530 on Normal difficulty; Cure Progress: 23%; Time: 1293 days . I didn't have the genes Metabolic Hijack and Aerocyte. The key gene is Creationist, I only had to devolve one mutation. Thanks again! Would love to see a no-zombie strategy :)

    • Vulshok 2 years ago

      Normal mode, 718 days, 17% cure, total score of 255140

      Boost, Darwinism, rurophile. Had patient zero be an american, took drug, saliva 1 2 then water 1 2. Let whatever mutate, if hyper mutates rack up 60 points and get up to resuscitation. if insomnia, get up to 45-50 .

      Then get everything strength related, if an isolated island decides to make a zcom base i allocate all points to zombie travel first.

      Rest is history, pretty fun mode if you get the hang of it.

    • Bob 2 years ago

      I thought it wasn't going to work because hyper salivation mutated, even with the creationist genetic code. It was noticed early on, so the cure started and got to around 70% before everyone got infected. Still, once I brought all the symptoms in, everyone turned and died quickly enough for me to win with the cure at about 90%. Pretty exciting, considering I've never even been able to win this on casual, let alone normal.

    • Alex 2 years ago

      Good tutorial. It was over for humanity after the psychosis upgrade but I still needed 1075 days, infecting Greenland is frustrating, ships never visit it lol. Cure was at 19%.

    • Ashleign profile image

      Ashleign 2 years ago from Alabama

      You don't get creationist from buying the game on PC.. It's just for the mobile version. If you play the free version on the mobile app, you can't use genetic codes.

    • aule 2 years ago

      I am playing on computer and bought it over steam, and i don't know about others but i don't get creationist by buying the game. What i can read it is random when ever you win a game.

    • Josip 2 years ago

      I don't know why, but im doing everything like in this guide, and i get mutation very early and can't beat the game. Yes im using Creatonist gene, but still. Any other guides or anything?

    • Plague: Downfall 2 years ago

      I used this on brutal difficulty. The first time I lost but the second time I ended up murdering everyone in 1399 days, with 31% cure. This adds up to five bio-hazards and a score of 126880

      I am aware of this, I have been working on a new tutorial for Necroa. Sorry for the inconvenience.

    • Ashleign profile image

      Ashleign 2 years ago from Alabama

      Guys I am working on a new tutorial for this one. I have found a much easier route. I hope I haven't added any new confusion and frustration. The problem is, I did this tutorial back before a few updates, since the game is still technically in Alpha, it's difficult for me to know when they add certain things since I have beaten the game time and time again.

      I hope to have this done soon. Also if you haven't yet, subscribe to me on YouTube. Video coming soon.

    • John 2 years ago

      Every time I play this even on casual I get a a mutation when about 3 or 4 billion people are infected.

      Yes I have Creationist.

      About 5 times in a row now I get a mutation.

    • Ashleign profile image

      Ashleign 2 years ago from Alabama

      I am working on all of these guys. It's not an easy task. I have to record 5 or 6 times, then work them over and over to make sure there aren't any curve balls. It's a unique process.

      Lol I've finnished necroa virus with 176800 score 21% cure within 1606 days on my first playthrough, thought this would be harder. Creationist FTW.

    • Catie 2 years ago

      I would like to point out that the creationist gene only decreases the chance of mutation. I used it and still got random mutation.

    • Ashleign profile image

      Ashleign 2 years ago from Alabama

      I have tutorials for all of them Nomen. Take a look up the page there.. There are all the links ready for use.

    • NomenNescio 2 years ago

      Fair enough. It's just that I can't play all the other levels first, because you have to defeat the preceding level to unlock the next one.

      But yeah, ok. Guess I'm stuck at the worm-thingy until I can get creationist :)

      Also, it seems that the Swedes are overpowered, since even if the rest of the world is zombiefied, they remain unaffected. Must be those damn köttbullar they eat :D

    • DannyBoyAndThePipes 2 years ago

      I still won, it just wasn't a perfect victory.

    • Ashleign profile image

      Ashleign 2 years ago from Alabama

      Yea Necroa isn't a level you want to start with..

      As a matter of fact. I played it last. So I would consider that. All others. I have once again whipped this ones ass using my tutorial. I am working on another walkthrough for this one on MB so, maybe that will help.

    • DannyBoyAndThePipes 2 years ago

      Nomen, you will need to unlock it by playing and or winning games on any difficulty.

      But even then, you probably still have to deal with mutations. Every time I've played Necroa to this guide, Hyper Salivation mutates just before the zombie phase.

    • NomenNescio 2 years ago

      Problem is: That "creationist" gene that you're talking about....isn't available. And yes, I have bought it (steam). All the other tutorials have worked, but not this one. I can't get it to spread to Greenland, and Z-com keeps me from suceeding elsewhere

    • Ashleign profile image

      Ashleign 2 years ago from Alabama

      I am currently working on all the Mega Brutal tutorials. It requires that you use the correct genes. I could wing it, but it wouldn't be a cookie cutter tutorial.

    • Holly Garland 2 years ago

      Im looking for mega brutal tutorials. Do u have em? Your very helpful and ive beaten a lot of it but keep trying and failing mega brutal. I named my bacteria & virus Hollyhell, lol thanks

    • Ashleign profile image

      Ashleign 2 years ago from Alabama

      With the creationist gene you shouldn't have any evolutions. I strongly recommend using genes for this tutorial. However, If you were to get a mutation toward the end, I would allow the symptom and try to make it as deadly as then possible. Wing it from there and be sure to keep those zombies from rotting. There are also some other cool abilities at that point as well such as floating zombies and what not. I do have a video for this one. But with the busy work schedule I am on and with podcasts and what not I haven't had time to upload it. Good Luck, If you have any more questions please don't hesitate to ask.

    • Yuri 2 years ago

      I have a question. If your disease evolves a random symptom before you can start the zombie phase what do I do? do I pay to devolve or just let it be? BTW loving your tutorials.

      X912, You do need to use Creationist for this tutorial. I am working on a work around for the genetic codes.

    • chillbilly 2 years ago

      Guys. I have a video for the tutorial. I have done it at least 20 times and I have won every time. There has got to be something wrong. X912. Are you getting the transmissions in their exact order?

    • x912 2 years ago

      I'm doing exactly as the tutorial says and I've failed 8times now.

      /every/ single time there are at least 4 mutations before every person has gotten infected and if I devolve them, I lose precious DNA, if I don't; the disease gets detected and a cure is dispatched far earlier than everyone dies.

      No idea what I'm doing wrong

    • Jinx 2 years ago

      I've also just won with this tutorial on Brutal. Took a couple of tries and a couple changes to the gene modifiers to make it work, and a bit of luck.

      Took 1530 days, with cure progress at 24% and a 5 star score at 141330 points!

      So, it IS possible to beat brutal mode with this tutorial ^^

    • Jinx 2 years ago

      It took several tries but I finally won with this tutorial.

      Took 1191 days, with the cure having gotten to 23% and got a 59350 point 4 star score. Best score I've gotten so far with any of the plague types ^^
