Civilization, Six Cities and Three Additional Resources

There are redundant resources in 6 cities and 3 cities of Civilization, which can be developed.

The Fourth Ring Road is generally used to build airstrips, missile wells, forts, etc. You can also plant trees for national parks. As long as there is a grid in the Third Ring Road, there will be tourism achievements. There are bonus resources in the fourth ring road, which can be harvested directly.

Fighting tips

1 For example, archers sitting in enemy cities can be lured out with the remaining hammers.

2. Computer gunmen and stick soldiers hate your scouts, probably because they prevent you from rushing out of the besieged city and hitting you. They can ambush archers, trap you and kill you.

3. Computer immigration has three perspectives. If the computer judges that there is no danger around, the immigrant will come out, unaffected by trees and hills, so you can ambush and monitor his main city with scouts with three mobile units.
