Plague Inc. – How to Beat Necroa Virus on Normal

The Necroa Virus in Plague Inc. is essentially a Zombie plague that acts completely different than any of the other plague types.

Certain Necroa abilities aren’t unlocked until you get to the Necroa symptoms. It also completely removes the Evolution Gene and replaces it with Necroa genes that have to be unlocked by beating the Necroa virus.

Gene Setup

DNA Gene - Cytochrome Surge (Get more DNA from popping orange DNA bubbles)
Travel Gene - Aerocyte (Increases the chance of your plague spreading by air)
Necroa Gene - None
Mutation Gene - Creationist (Reduces the chance of mutation)
Environment Gene - Extremophile (Minor bonus in all environments – I like this one instead of the specific environment bonuses, but it’s not vital)

Necroa Strategy

This one took me a few tries to figure out. Here is the basic strategy that I used to beat it the first time.

Start in India, as it has a large population and access to both an Airport and Sea Port. It’s also a hot and humid country which will give you a boost to hot and humid environments, and you’ll only need to purchase cold type abilities.

Don’t purchase any Symtpoms until the end of the game when everyone on the planet is infected. If you have to devolve any mutations early in the game, you might as well start over because you may not have enough points at the end to finish properly since devolving is extremely expensive in this plague type.

Start off with Blood 1 and Saliva 1 in Transmissions. Also purchase Drug Resistance 1 and Cold Resistance 1 on the Abilities page once you build points.

As you get more points, purchase Urogenital Expansion, Gastrointestinal Expansion, Air 1 and Air 2 for Transmissions. Also purchase Cold Resistance 2 for Abilities.

From here it’s a long waiting game. You’ll literally ride out this build until the entire planet is infected with your plague. Hopefully by the time everyone is infected you’ll have 60+ points banked up. If you’re a little short, then keep waiting a little longer to pop some of the orange DNA bubbles, or until you get a free Insomnia mutation.

Once you’re ready, purchase the following symptoms: Insomnia, Fever, Photophobia, Delerium, and Cytopathic Reanimation. Once you purchase Cytopathic Reanimation, you’ll start the Zombie phase.

The rest of your purchases will be making your zombies stronger and better at killing. Anaerobic Reanimation, Enhanced Motor Control, and Enhanced Sensory Integration were the first ones I picked.

Soon the world should create a zombie task force called ZCOM, which will attempt to go out and kill your zombies. This is represented by black zombie bubbles that you can pop, which will your biggest resource for the end of the game.

The cure will start building fast, but you should also be getting points very quickly while popping ZCOM bubbles. Keep throwing more points at more zombie symptoms and abilities, focusing on making your zombies stronger and making them decay slower.

Soon, the cure will essentially stop and the world will throw in the towel. Congrats on your first Necroa win!

    DAMN!
    Insomnia just won’t stop mutating by itself, i had more than 50 points, and i devolved it till 0 points, this was just ridiculous

    This virus is a joke. I got insomnia mutated FOUR times before I got a single orange bubble (Which I had combined with the gene that increases points, only to give me 1 – 2 every pop). Don’t forget I was also using creationist which in itself is a complete joke. This is the least fun playthrough I have done through the entire main game. This is one instance where they need to just remove this content from the game.

    that strategy worked like a charm. i didnt wait for the whole world to be infected though. once insomnia inevitably evolved i went with it. as long as you keep upgrading the lethality of your zombies, you only need the “reanimation” necroa ability to hit z-com harder. it worked amazingly well, compared to my attempted strategies.

    it may be a difference in version but yea creationist rarely EVER works the way you say it does. And once your gene does mutate it tends to mutate as if creationist isnt there so you get screwed…i suggest you redo your guide or at least attempt to replay the game before asking if people are using your gene selection…does not work on brutal or normal…

      Latest version, and Creationist still works fine for me. As I stated, it reduces the chance of mutation, doesn’t negate it. I find mutation one of the toughest battles in this plague type.

      It’s silly to assume that I haven’t played recently before suggesting to look over their gene selection. While this guide was written when Necroa first came out, a lot of it is still applicable. Creationist isn’t flawless, and the randomness of mutation will get you on this one sometimes.

      Simply stating “does not work” doesn’t help much honestly. This is a guide after all, for you to use to help develop your own strategies. That being said, I’m working on updating the guide, but Creationist is still at the core of the genes I use for this one.

    I tried with your tactic and couldn’t get it. When I finally infect everyone I don’t have enough DNA pounts to turn them Into zombies

  6. Andrew says

    It’s a really good strategy. But my problem is that once I get 3 billion infected it starts to mutate which gets really expensive and causes me to lose all my DNA before everybody is infected which ends up getting my spotted and cured. Any ideas?
