while genes probably don't make a huge difference most of the time, I would recommend you follow this gene setup, or a similar one:

metabolic jump

darwinist

native biome

extremophile

thermonecro


while you can probably switch a few genes safely, like thermonecro, I STRONGLY SUGGEST leaving metabolic jump, darwinist and native biome in. I will explain why in the next section.

as usual, start in india. the FIRST thing you want to do is evolve segmented genome once you can afford it. after that, evolve zoonotic shift and bird 1. this should be enough to spread the disease fast enough so that by the time people know about it, it's global, yet slow enough so you can build up dna, which is where the darwinist gene comes into play. if you just let the disease mutate symptoms instead of evolving them yourself, you can save a LOT of dna to use to strengthen zombies later on, AND mutations can strengthen zombies as well.

once you evolve bird 1, simply sit back and let things happen. it shouldn't take long for the disease to start spreading to other countries, which is where metabolic jump comes into play. red biohazard bubbles will pop up VERY rapidly when your disease starts spreading, especially with bird 1, which allows you to gain a very large amount of dna early on, which is very important. right around now your disease will likely have been spotted. once it's spotted watch the cure progress closely while continuing to pile up dna as fast as possible. remember to watch what symptoms mutate, as well. if the cure progress is going up rapidly, evolve cytopathic reanimation asap, then evolve as many of the following symptoms as you can: dermal calcification, cranial elephantitis, bone dysplasia, acidic reflux, naja mordis, and autothysis. the larger the zombie combat advantage, the better. after spending your dna on symptoms (remember, the ones listed earlier are TOP PRIORITY) save up a bit more and evolve horde instinct, and every trait down that path. soon, ZCOM will set up, and you'll want to be prepared to attack asap so they don't become too powerful.

once ZCOM sets up their first base, if you have a neighboring country with zombies, send some over to attack. if they die out, just send more. you should be getting more than enough dna to swarm them with hordes and kill them off. however, if they start building more bases, take them down as soon as possible so they don't grow too powerful. at this point your only focus should be destroying ZCOM. destroying ZCOM is as simple as sending multiple hordes their way to overwhelm them. if they keep killing your zombies, it's best to simply keep sending more to whittle away at them and eventually destroy the base. repeat this for every base that exists, and you should be good to go.

after ZCOM is destroyed, simply send zombies to any country that's not infected or destroyed. because there's no resistance you're completely free to finish off the human race. GG 2 EZ
