Walkthrough - How I beat Parasite on Mega Brutal - Plague Inc

For Plague Inc addicts only (ie, nothing to do with the usual stuff on my blog!)

I've beat Parasite on Mega Brutal three times using this route, twice with loads of room to spare!

Android only, on my tablet - I don't know if it works on Xbox One or any other device.  (Note: April 16: someone has just told me that it works on iPhone too, though they had to get Coma and Paralysis at the end to stop the cure getting to 100%).

Modify with these genes:

DNA Genes: Cytochrome Surge

Travel Genes: Teracyte

Evolution Genes: Patho-Stasis

Mutation Genes: Genetic Mimic

Environment Genes: Xerophile

Start the plague in Egypt.

Get Symbiosis 1

I've found that the trick with Parasite is to get it spread round fast, before you do anything else....

.... so get Air 1 and 2, and Water 1 and 2 first.

Next, get Drug Resistance (DR) 1, because it might already be in countries with good medical facilities.

Then get Symbiosis 2

If you get any random symptoms mutating, devolve them immediately, so as not to draw attention to the plague.

Next:

DR 2

Cold Resistance (CR) 1

Symbiosis 3

CR 2

Around now there should be signs of the cure being about to start - the notification that the plague is more infectious than HIV is the sign that this is about to happen.

You need to make sure you have 7 points in the bank for Genetic Hardening (GH) 1 for when this happens - get it AS SOON AS some country starts looking into it!

Evolve Coughing and Pneumonia.

Now that it's been discovered, if any other symptoms mutate of their own accord, you might as well leave them, but have a look first to see if devolving them will give you a point back.

You should get GH 2 as quickly as you can; both GH slow the cure pace down A LOT.

Now it's just a matter of waiting until the whole world is infected.

Do not slow the cure with any Genetic Reshuffles (GRes) until it is over 60%.  It goes back by a larger percentage if you wait until then, but sometimes only by 1% if you do it too early.  Also, you will need your points to kill everyone!

One time, it mutated Pulmonary Fibrosis of its own accord; if it doesn't, you should get this now.

Do not be tempted by Total Organ Failure (TOF) until the whole world is infected, as it kills them off very quickly and will leave no-one to infect the healthy.

As soon as the whole world is infected, devolve Air 1 and 2, then CR 1 and 2.  This will give you 6 DNA points back.

The last time I played using this method, the cure was only at 18% by the time the whole world was infected, and I had 50% DNA points - I only needed 9 more for TOF!

Get TOF as soon as you can.  

This is what happened to me next:

After TOF started killing everyone, I got enough points for GRes 1 when the cure was at 61%, and it took it back to 57%. 

After that, the DNA points were coming so thick and fast that getting GRes 2 and 3 was easy.  When I killed off the whole world, the cure was only at 68%.  Finished on 11960 points.

I've played it a couple of times using this method and got beaten; it all depends which countries get infected when.   Try it a few times!
