818839_larger-1If you've not yet played Plague Inc. [$0.99] by Ndemic Creations yet, you better think about it, as while the whole "world infection" genre is nothing new, Plague Inc. absolutely nails it on iOS devices. It's only gotten better with recent updates too, as they've added a whole slew of new diseases and ridiculously difficult achievements tied to those diseases.

A recent update brought us the Necroa Virus, which allows players to infect the world with a zombie outbreak. Of course, you could turn everyone to zombies, or, if you want to satisfy the requirements of the "Not Another Zombie Game" NAZG achievement... You'd kill every human on Earth with the Necroa Virus without turning them in to a zombie. TouchArcade forum member and Plague Inc. fanatic Botoshel figured it out. In fact, if solving these sorts of puzzles in games suits your fancy, check out the Plague Inc. forum thread where you'll find all sorts of people who are similarly all about this game.

Now, if you want to figure out the NAZG achievement by yourself, stop reading now. This guide is a 100% solution to unlock the achievement. You're still at the mercy of the random number generator powering the game, so it's not going to work every time, but I've been able to duplicate Botoshel's method with the following steps:

Start a normal Necroa Virus game in India with the following genes equipped:

  • Cytochrome Surge to get bonus DNAfrom popping blue cure bubbles.
  • Aerocyte to increase the changes of your plague spreading by air.
  • Spliced Activation to decrease the DNA cost of active abilities.
  • Creationist to decrease the change of your plague mutating.
  • Xerophile to give your plague a bonus in arid climates.

From there, head to the Transmission screen and evolve "Saliva 1" first. As soon as you have the DNA, evolve both "Zoonotic Shift" and its followup "Bat 1" to spread your plague using bats. From there, sit back and pop DNA bubbles while your infected total climbs towards 100,000,000. What you're looking for is a news story in your feed that mentions rabid bats.

IMG_0080

If you cross 100,000,000 infected and don't see a message regarding rabid bats, start over. Once you do see the news story, head over to the Abilities screen and start evolving "Drug Resistance 1," "Genetic Hardening," "Gene ReShuffle 1," and "Gene ReShuffle 2" as you get the DNA to do so. Once you've got all your resistances in order, go back to the Transmission page and devolve "Bat 1" once you can afford to do so.

IMG_0082

Once again wait popping bubbles until you see a message about WHO starting a rabies eradication initiative and then film about rabies becoming a global hit. At this point, evolve "Gastrointestinal Expansion" in Transmission followed by both "Cold Resistance 1" and "Cold Resistance 2" in Abilities to spread your disease.

If everything is going as planned, you'll just be sitting and waiting for your disease to spread as it remains completely undetected. This can take a while, especially across both Russia and Greenland which both seem exceptionally stubborn. Turn your sound up, and do something else- Stopping to pop the bubbles that appear.

IMG_0087

Once you get the popup that says the whole world is infected, high tail it to the Symptoms screen and dump all of your DNA into:

  • Insomnia
  • Fever
  • Photophobia
  • Coma
  • Acute Encephalitis
  • Hyper Salivation

Things will be happening fast now, as you've got the entire planet infected and now suddenly everyone is dying. Subsequent popups will appear about a disease being found, and a cure starting. Be patient, and wait for the popup that says your disease is "a form of Rabies."

IMG_0089

At this point, as soon as you have the DNA for it, devolve "Zoonotic Shift." People will begin dying, and cure research will progress well. However, this last-minute devolve will cause the existing research to be wasted which should line up well with the death count being high enough that there's not many people left to continue working on a cure at any reasonable pace.

IMG_0090

From here, you just sit back and relax. The game should be on cruise control now for complete world destruction without you doing anything. In my experience, the last few survivors are very stubborn and can take quite a while to die. But, just make sure your iOS device is plugged in and let it do its thing.

IMG_0093

Now, in my experience trying to duplicate the steps to unlock this achievement, I've discovered a few things. First off, if you experience any mutations it's best to just start over. It's vital for your plague to remain very far under the radar. Mutating symptoms is a good way for the opposite to happen. Sure, you can devolve symptoms away but you need tons of DNA for when the whole world is infected to break out the whole bullet list of symptoms above.

Additionally, the pertinent rabies messages are not popups, and rather are just yellow colored news stories that will appear in your news ticker. Unlocking this achievement from start to finish will take you around an hour, as spreading your plague with this method will take a very long time. Also, as mentioned, without actually turning people to zombies the killing process will also take quite a while.

Thanks, Botoshel!

  • Botoshel

    I should be thanking you for writing this wonderful article :) . This really was my dream as a Plague Inc player. And i've managed to acomplish it. But that wouldn't have been possible without the support of you guys. Thank you for believing in me,for supporting me in those long hours that took in order to get it done. And i would also like to thank mr Vaughan for creating an amazing game which without doubt,is one of the most brilliant games i've ever played.

    • TarePlays

      You didn't win an Oscar bro

  • James Vinson

    Just letting you know, the starting genes are wrong. Not sure about the rest but stopped after that.

    • Botoshel

      The genetic code which i've used is not necessarily unique. That code is what i thought is the best way to achieve this as you cannot use metabolic hijack because you cannot use any symptoms until you've infected everyone and catalytic switch is useless :)

      The code has less to do with the achievement itself.

      • James Vinson

        No, that's not it. I just meant that Cytochrome Surge refers to the extra points when orange bubbles are popped, not the blue cure bubbles. Could get some non-experienced players confused. I completely agree as well, catalytic switch is useless.

      • Botoshel

        I know what Cytochrome Surge is.. But given the fact that you need to evolve saliva and zoonotic shift and bat 1 pretty damn fast,it is the only way you will get enough dna to acomplish this xD

      • James Vinson

        Lol, mate, I didn't mean anything by it. I loved your guide. I was just saying that above, the wrong name is there. Just trying to help other gamers that might not catch it.

      • Botoshel

        Ahhh i see what you mean.. He wrote the name correctly but the description of the gene is wrong :) Didn't see that in the first place.

  • getsuga04

    i'm on my 5th restart... can't seem to get the bat message?!

    • Botoshel

      I hope you're running on 1.6.1.. You will get it eventually ;)

    • JayTay

      I've tried 10 times so far with no luck :(

      • Botoshel

        I've tested the bat message on 11 games.. It occured 3 out of 11 times

      • JayTay

        Just to follow up, I tried about 10 more times with no luck at all. Put my phone in Airplane mode as seen on the forum thread and bingo, bat message first time!

      • Botoshel

        Maybe mr Vaughan has the sense of humor :) Bats were the key to NAZG.. bats fly.. Airplanes also fly ;))

      • getsuga04

        must try it. been trying since yesterday and only got it twice...

      • getsuga04

        this is the hidden piece of the puzzle! got it the 1st time! removes the games randomness... brilliant!

    • Guest

      I think i figured out how to constantly get the 'rabid bats trigger town evacuation' message...PLAY the game at NIGHT..whenever i play in the morning, no matter how many times i tried, i never got the message..but when i played at night, boom, 3 out of 5 times i get the message..bats active at night, sleep during the day..

  • Dueler

    Earned this game through freeappslots a while back but never actually ran it, probably still wont play it tho dunno why just cant snap into it. Tho the write up was very interesting.
    either way good work boto im sure it took a helluva long time to figure that one out and i commend you for sticking to the challenge.

    • Botoshel

      Thank you :) It was quite a challenge

  • ZarieoZ

    Did they ever think of making Plague inc. in reverse, like an extension to the existing game. Like AI is the plague & the player is in charge of making the necessary sacrifices & decisions to save as many countries as they can & developing cure, as well as deciding to open/close airports, kill this country in order to save the rest.... Micromanagement, you know.... Like plague inc in reverse ;-) which can then lead to multiplayer with someone playing as the plague & the other as the fighter/cure developer :-)

  • Jakewobegon

    I know it was said that the achievement was always something that could be done even before the update. Anyone have luck with similar strategy without the breadcrumbs on Android?

    • Botoshel

      None that i know.. Android players are getting angry cause they feel betrayed. But i think it's possible,it's just a matter of timing and luck :)

      • Jakewobegon

        Thanks for the response. :) And betrayed? Seriously? We're getting it next month in spite of the fact that apps for Android have to work for Gingerbread, Honeycomb, Ice Cream Sandwich & Jellybean as well as deal with the quirks of the different manufacturers. Seems like people need to calm down a bit. O_o

        Congratulations on cracking the achievement. Looking forward to the update next month.

      • Botoshel

        Thank you :)

  • Jone

    I have a little problem. I made it that the whole world is infected, then i evolved those symptons BUT 'is a form of rabies' message didnt appear. Im using 1.6.1. Does anyone else have this same problem?

    • Katherine Kroll

      Same issue here

  • Jone

    Now i have done that trice in a row... What am I doing wrong?

    • Botoshel

      Did you first get the rabbies messages? The bat message,the WHO message and the film about rabies?

      • Katherine Kroll

        Yes yes and yes to all 3 messages have tried this now 4 times but it will not give me the rabies comment

      • Botoshel

        Are you playing on Brutal? Or casual?

      • Jone

        Im playing in normal.

      • Jone

        I got them all and i did everything exactly as in this page

  • Katherine Kroll

    So can anyone answer a question? I followed all the steps evolved all the symptoms listed made sure all the proper pop ups came before I did all of this and kept waiting and waiting for the is a form of rabies pop up message to show...never came and my plague was cured. Was frustrated because this happened after I had put in most of the wait time for the other RNG stuff. Does this happen often? I had not devolved zoonotic shift and I made sure I followed every step exactly.

  • Botoshel

    This is strange.. I've tested it twice and it works just fine..

    • Katherine Kroll

      I've tried it on casual normal and brutal nothing works : /

      • Botoshel

        Brutal is impossible :) Needs to be rebalanced. On casual it should work. I haven't heard of this issue before. I've heard some people saying that the final pop up never came but this.. This is news to me. Make sure to have hypersalivation as the last evolved symptom. Like i said.. I already tested this twice already since you guys posted this issue but i never came across it. Gonna try again. You make sure to play on CASUAL as that guide is made for Casual... Not normal dificulty.

      • Jone

        Oh casual... On your tutorial it says 'start a NORMAL necroa virus game' so i think that you should change that to prevent misunderstandings

      • Jone

        Well... Now i tried it on casual and I actually got that 'form of rabies' popup but cure was already at 100% then

      • Botoshel

        Actually that's not my article :) you should contact the author. Btw.. Tried again.. I get the pop up about rabies each time..

      • Jone

        Now I got it too

      • Botoshel

        Good job :) To get ot you have to devolve zoonotic shift and if that fails evolve poliphagia or autophagia if you've got enough dna.. But that doesen't really matter as long as you get it.

      • Katherine Kroll

        So just got it and I think I figured out the problem based on your comment. First the author should update the guide to say casual, and secondly they should specify NOT to upgrade all the symptoms at once because the guide makes it sounds like you should. Every single time I upgraded all the symptoms at once I never got the rabies comments but as soon as I waited for the comment about doctors detecting a new minor disease, I then upgraded hyper salivation last like botoshel suggested and it worked perfectly.

      • Botoshel

        Glad it worked for you :)

  • Benegesserit

    Turn your sounds up and do something else? This game doesn't sound very engaging. How is that fun?

    • Botoshel

      It's an unique case in this achievement as humans die slowly :) Otherwise it's very challenging and addictive somehow

  • mtvvicky

    I think i figured out how to constantly get the 'rabid bats trigger town evacuation' message...PLAY the game at NIGHT..whenever i play in the morning, no matter how many times i tried, i never got the message..but when i played at night, boom, 3 out of 5 times i get the message..bats active at night, sleep during the day, eh..

  • http://www.dnaustrem.com/ DNA

    Can someone give me a rough estimate of how often the colony of rabid bats banner shows up. I've tried this guide about 20 times and so far I only got the banner show up once, on brutal!

    Evolve Saliva 1
    Zoonotic Shift
    Bat 1
    then wait until banner shows up however every time I keep going over 100 million.

    Any suggestions?

    • Botoshel

      3 out of 11 tries at my last test on this issue.

  • James Vinson

    Tried this on brutal, normal, and casual, did everything exactly like the guide said, but I never get the "is a form of rabies" popup while the cure is being developed. Running 1.6.1, any ideas mate?

    • Botoshel

      Never happened to me. Did you leave hypersalivation as the last symptom to be evolved?

      • James Vinson

        Yeah, it worked immediately though after I found your post on the TA forum and tried going exactly from yours. A couple slight differences and it made it perfect. Tried to post the link last night, but they won't approve it. Hilarious since it is to their own forum.

  • mclarensf1

    So, the rabid bats news line should show up at 100,000,000 infected correct? Cause for me it showed up at 100,000 infected.

    • mclarensf1

      Well it still worked so yay. But question, has anyone tried or succeeded in destroying the whole world without anyone discovering their plague?

      • Botoshel

        It's impossible because once lethality or severity are increasing they discover your plague.

        Still you can do something like that on Neurax worm. Infect the whole world,keep a low profile and after 100 percent infection go all the way to transcendence.

    • Botoshel

      No.. The bat message could show anytime but usually it shows BEFORE 100.000.000 infected. It usually shows after 3-5 months since the evolving of bat 1

  • Hazardous Roo

    I'm immensely frustrated with this accomplishment....got all accomplishments in version 1.5 EXCEPT this one. I've tried airplane mode, I've tried at all hours of the day and night, I've tried every piece of advice I found. I can't even get the message about 'rabid bats' to come across the news ticker. Ever. I've made at least 20 attempts so far (not an exaggeration) and I've still had no luck. And yes, I HAVE evolved Saliva 1, Zoonotic Shift, Bat 1 ASAP.
    What am I doing wrong here? Does it ONLY show up on 1.6.1? If so, I'm out of luck, 'cause that's not available for Android yet.
