Seriously, the hero needs a major upgrade to last the extra and trial stages. Maybe unlock 9 more upgrades at the extra stages and then 9 more at the trial stages? That or they need to not randomly go forward. It's hard to keep track of them and when that happens, they last seconds. It's a little frustrating when you've been fighting for however long and then you lost because your hero commited suicide.
walkthrough: This is how to get the impossible badge For realistic mode: 1) Pick Virus. 2) Start in Canada, New Zealand, Cuba, Greenland, or Madagascar. 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, keeping whatever symptoms it gives you. 9) Buy fever, fatigue, diarrhea, pulmonary edema, and hypersensitivity. 10) =) Wait until everyone dies AND keep this comment alive!!!
