@chippi, it has to be a one hit without use of any talents, and it can be done on anything. Easiest way to get it is to reset talents and go back to the beginning area's until you get the achievement.
I would like to see the option to buy more bank space if you need it. Other then that This is my favorite idle game.
@vestilynde, seriously scroll your cursor over the talent icon.. It says you start earning them at 10
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. KEEP THIS COMMENT ALIVE Thanks for the comment
