Omanga has developed nuclear technology and started to use nuclear plants to generate power. As nuclear power is far more efficient than fossil energy, they have more resources to develop biochemical and mechanical technology. Omanga has expanded the use of nuclear power to an unprecedented level. Finally its first generation nuclear plant at the north exploded in an accident and released large quantities of radioactive particles into the atmosphere. This catastrophic disaster has contaminated half of the territory of Omanga and some of the neighbouring states. Most of the populations at the north moved to the south. With resources pressure, Omanga has become more aggressive and started its invasion to the border of Gafia.
