This is a map full of strategies. The development method of each location is different. There are early headwinds, which must be fast-breaking, and early tailwinds, but they are easy to be caught. The location in the center of the map is the most challenging. If you want to play tower defense, you can choose the leftmost center, except for the nuclear bomb. There are everything else, but the disadvantage is that you will be short of money in the middle and late stages.
