It's the year 20XX; military conflict between the League of Nations and UNITA run rampant across the globe, prompting small scale wars to break out in various regions. In order to combat UNITA's biochemical modification of humans, the League of Nations secretly developed the NRC: Insectoid Robots with frightening intelligence and a brimming consciousness, which sooner than not went rogue and became its own faction in this now-three-way war. The human world is now at stake, and a battle for survival and supremacy is being waged.(Storyline via IGDB)
