first you have to choose your difficulty.
then you choose your disease.
then you modify your genetic code.
and abilities all plague types have a different abilities like bacterias ability is bacterial resilience makes the plague more immune to medicines, hot, and cold or virus ability Viral Instability witch makes it more often to mutate symptoms witch is a bad and a good. good in that you can get symptoms with out buying them so you can get transmissions. the bad part is that you can kill your self off!
plague inc is a complex game with a lot of things you need to balance like if you kill 1,000,000 people a day and you infected 50,000 people a day you kill your self off and then it is game over for you
the neurax worm is different for a lot of reasons one is that you have all different symptoms, transmission and abilities. for the abilities you have an ability that makes you move a lot of your worms to a new locations.
for the transmission you have new transmission things like eggs, genetic swap witch makes it mutate
symptoms more often, and concertina locomotion the host moves faster.
the last plague is necro virus or the zombie virus!
a zombie virus that is a lot like the neurax worm you have all new symptoms, transmission and abilities
symptoms more often, and concertina locomotion the host moves faster.
for symptoms you have all new ones things like OCD were the hosts collect worms, and hallucination.
the last plague is necro virus or the zombie virus!
a zombie virus that is a lot like the neurax worm you have all new symptoms, transmission and abilities
for the abilities you have the same hot and cold but the new things are, you have two new powers one is that you can send hordes of zombies out to kill off country so if you sent your horde to greenland and you infect them(no more greenland problems)! and reanimate off a lot of your zombies die in a country then you can reanimate them (i think it is one million of them at a time). the BIG problem is humans can find the cure and you wont louse(but it will be a lot harder to win) so the real problem is Z-COM(not my name for it they named it!)Z-COM is a group that sets up a base and KILLS all of your zombies(the only way i found to kill Z-COM is sen a lot for hordes at them like 6-12 hordes i mean it they are bad!)as the days go on Z-COM gets a new base and then another and more and more bases until you kill your self off and you die!
(there is no google/bing photos for this virus sorry but now you can try to find them for your self sorry)
so for the symptoms you have the red ones helps the infectivity and the black helps/turns them into zombies that have things like rats 2 or peptide surge i think it makes your zombies faster.
and the transmission you have saliva witch make you infect faster then you have blood same as the blood in the bacteria
and that is about it for plague inc I hope it was informative and enjoy!
