Start with virus. Then sell starting symptom. Add resistence 1-1-1-1. and buy airborne and rodents. Then wait until all locations are infected. then buy whatever u want to kill of the human race. Took about 10 minutes with 3x speed and started in argentina.
A glitch cheat. If u surrender a game then all the characters would appear in the same spots plus if u had all ur units out u would send them again. So that means u will have 6 hero units on the field.
