I've redone my old Zhakul Das Contortum map.
This time around, your bases are of average size, you have a fairly easily defended natural and rocks going to a second expansion on the same cliff level, also quite easily defended.
Taking your tertiary, on the other hand, is quite difficult. Rocks going from your second expansion will open up a high yield, but this base is quite vulnerable to the adjacent natural expansion.
There are four xel-naga towers lining the center of the map.
Comments are welcome.
