2) Play it smart with transmissions.
- When you begin upgrading your transmissions, use some sense.
- For instance, water and air is a always a good way to spread a disease.
- Upgrade them to the highest capacity before you select any other transmissions.
- Build your transmissions around where your disease begins and adjust as it spreads.
- Keep in mind, if your disease spreads too quickly, you may have a hard time fighting off research for a cure.
3) Make it deadly asap.
- After you have upgraded enough transmissions, it is time to turn your disease into instant death.
- Upgrade your disease to the point where it is almost instantaneous.
- Your disease should be able to sneak into a country unnoticed.
- This way, it can cripple a nation before they even have time to react.
