Some time is given for the initial arrangement and research of necessary technologies. Then enemy bases begin to appear around the player's structures. Initially, this will be one (main) structure and one unit of protection. Gradually, the base accumulates resources and creates child buildings (they regenerating the main building), which can create units. Having absorbed the pollution witch the player created by, the base progresses faster. This is the progress of the base, it is not tied to evolution. With the evolution of all enemy buildings and units are changing.
