Hi
thanks to thanatos8285 for the idea of the dispatcher and the medic.
it is with these 2 characters that I managed to do it.
(I put the medic first and dispatcher the second)
We easily get to 3 eradicated diseases.
Many times I could have arrived at 4 but I missed 1 round lol.
I don't really have a technique to give.
It's a bit depending on what's going on in the game.
to have it I treated the cities with the medic. I used the skill of the dispatcher to easily move the medicine once the illnesses had healed.
I also used the dispatcher to join the medic or have the medic join the dispatcher.
concerning the cards I gave to the one with the most of the same suit.
As well thought of setting up centers to cure illnesses it saves time by avoiding returning to Atlanta.
I hope my comment will help you get it.
