1)Pick Virus.
2) Start in Canada, New Zealand, Cuba, or Greenland If you do not get there restart.
3) Sell the starting symptoms, if any, and buy sneezing (unless it is what you started with, just keep it).
4) Buy 1-1-1-0 resistances but no transmissions (they trigger closures). 5) Once four countries are infected, sell sneezing to get rid of visibility.
6) Wait until all countries are infected. If Madagascar closes its shipyards or is not infected in 30 days, restart.
7) Buy all four drug resistances AND sneezing, coughing, and vomiting.
8) After a few days, unlock tiers 2-3, (do not buy tier 4 ever!) keeping whatever symptoms it gives you.
9) Buy fever, fatigue, diarrhea, pulmonary edema, and hypersensitivity. Then save for kidney failure and ataxia.
This really works it worked for on realistic and got me the imposible badge.Pass it on!
metal ballons can be destroyed with cannons only and to do the glitch: buy one tack shooter, then press tab till the yellow thing is around the speed upgrade and push enter till it says hyperspeed(if you push enter too many times you can't get to buy a cannon in the future)
Thanks for the comment!
