The first phase of the Mutation Disaster was an irregular outburst across the entire planet. It signified the first time the Mutation Source controlled its strength. The first symptom of the second phase was all the infected individuals acting up together. Compared to the first phase, the Mutation Source would not be limited by controlling ordinary individuals. Certain elite soldiers and weaker Supers could also become targets of its control. The most obvious change would be the fact that the infected individuals no longer acted randomly but acted as though they had a goal.
The objective behavior of the infected individuals was the first sign of the Mutation Source gaining intelligence. Compared to the chaos in the first phase, the escape of all the refugees was due to the control of the Mutation Source.
