The source of the conflict came as a result of Kane's alliance with GDI leading to the Brotherhood of Nod to cooperate in the creation of the Tiberium Control Network. However, many of Kane's followers decided to rebel and began a series of attacks against the TCN construction sites as well as on GDI. Initially, they were fought off by GDI's use of Predator Tanks but this led to the Separatists in adapting their tactics by modifying their existing Flame tanks with more armor as well as enhanced with better speed to escape retaliation. Their actions proved to shift the balance of the conflict in the Separatists favor and over a dozen Tiberium Control Network sites were lost in the fighting in 2064.
