Omniums were originally built by the Omnica Corporation to develop self-improving robots called Omnics. The factories were closed down when the company was shut down for fraud. Then, thirty years ago, omniums across the world were infected by God Programs and reawakened, developing militarized Omnics with which to attack humans. Bastion was the standard unit produced by the Omniums, and other classes were produced as well, such as the occasional Titan.
