This guide honestly does work. Thanks to Guille100. [1) Pick Virus 2) Start in Canada, Greenland, New Zealand, Cuba (if not, restart) 3) Sell starting symptoms (if any), other than sneezing. If you don’t have sneezing, buy it 4) Buy 1-1-1-0 Resistances 5) Once your disease spreads to a few countries, sell sneezing to get rid of visibility 6) Wait until all countries are infected. If Madagascar closes or this is after day 30, restart 7) Pump 4 Drug Resistance and buy sneezing, coughing, vomiting 8) After a few days, unlock tier 2-3 keeping whatever symptoms it gives you 9) Buy fever, fatigue, diarrhea, pulmonary edema, hypersensitivity, hemorrhaging 10) Wait until everyone dies]
