You guys keep fussing about Madagascar. I just wiped out the entire planet in a 30 minute game.
Virus Name- T-Virus
All I did was eliminated all the symptoms and kept my heat resist at level 1 and made it airborne. Then waited until I had enough to increase cold and moisture 1 each. Then bought waterborne and insect. Keeping symptoms off. Took maybe 5 minutes to infect the entire world. After that I had over 100 points to go crazy with and bought a crap ton of symptoms to spread the virus quickly. Boom, headshot.
It's a good challenging game. I tried several tactics to spread my virus. Apparently eliminating symptoms lowers the virus's noticeability to the point it's invisible. I took a point because of Madagascar since it should have an airport as well at least. Other than that it's still a fun game to waste some time on if you're bored. I'd love to see a 3rd installment.
